OfficeSuite has an abundance of helpful keyboard shortcuts you can use to save yourself valuable time while working.

Purchasing a Premium license gives you access to everything OfficeSuite has to offer. Follow the links below to learn more about OfficeSuite's powerful Premium features:

The sharing options in all OfficeSuite apps are optimized for maximum ease of use and accessibility. Below we've detailed them for all platforms:

Navigating between the various menus and functions in OfficeSuite is done in several ways, the main one being through the Navigation menu accessed from the icon at the top left of the screen, both on phones and tablets (the main functions available in the Navigation menu are detailed below). Another way to quickly access some of the main options is at the bottom of the screen, there you'll find quick-access buttons to our proprietary MobiDrive, Home, as well as the Chats feature. Lastly, the Create icon at the bottom right side of the page opens an animated speed dial, allowing you to swiftly create or scan documents.

The Navigation menu can be accessed from anywhere in OfficeSuite, and contains the following options:

Sign in allows you to access OfficeSuite using a Facebook, Google, Apple ID or custom email account. Signing in currently allows you to sync app settings and recent file lists (for cloud accounts only) between all of your devices.
Upgrade to Premium will redirect you to a screen where you can purchase a Premium license or start a free trial. This option will not be visible to users who already have Premium.
Activate with key allows you to activate OfficeSuite Premium using a pre-purchased activation key.
MobiDrive is OfficeSuite's built-in cloud storage service, which allows you to access your files wherever you have OfficeSuite installed.
Create document allows you to create a wide range of document types from both blank and preloaded templates:
Scan to PDF opens Quick PDF Scanner, which lets you easily digitize any paper document as a PDF using your devices' camera. For help on using Quick PDF Scanner, tap on the Help icon from within the Quick PDF Scanner main menu.
Scan to Word opens Quick PDF Scanner, which lets you easily digitize any paper document as a Word document using your devices' camera. For help on using Quick PDF Scanner, tap on the Help icon from within the Quick PDF Scanner main menu.
Scan to Excel opens Quick PDF Scanner, which lets you easily digitize any paper document as a Spreadsheet using your devices' camera. For help on using Quick PDF Scanner, tap on the Help icon from within the Quick PDF Scanner main menu.
Convert to PDF allows you to select any compatible document through the Open document interface, and instantly convert it to a PDF file at a specified location.
Fill and sign opens any compatible PDF file for quick signature and certification operations (where applicable).
You can create new Word, Excel, and PowerPoint files either as a blank document from their respective Blank icons, or by selecting from the wide range of included templates. The color-coded More buttons will reveal additional templates for each file type.
Open allows you to access documents from wide range of local and remote locations:
Internal storage allows you to open files located on your Android device. The Contextual menu next to each file or folder lets you add it to your favorites for quick access, or perform more advanced operations using the File Commander file manager.
MobiDrive provides access to OfficeSuite's built-in cloud storage service, where you can access your files wherever you have OfficeSuite installed.
Add a cloud account lets you add an unlimited number of cloud storage accounts accessible by OfficeSuite. Added cloud accounts will display as separate entries in the Open interface. Currently supported Clouds include:
Google Drive
FTP allows OfficeSuite to connect to a File Transfer Protocol server, and access or edit the contained files and folders directly. To add a server, tap on Add in the upper right. You can then specify the server address and connection settings, among others. (Note that you must have appropriate access rights in order to modify FTP server contents.)
Local network lets you add network locations that are on the same wireless network as your Android device. This includes Windows/Linux file shares, NAS devices, DLNA-capable devices, and more. The Scan button will display a list of visible network locations, while Add allows you to specify a custom network location.

OfficeSuite's Chats feature allows you to communicate with your friends and colleagues via exchange of documents and messages. Chats are a very practical and quick way of coordinating team projects and exchanging important files without the need of writing emails.

Starting a new chat is quick and easy. One way is to simply send a specific document with the 'Send' button while inside of the document. Another is via the document lists (in Home and MobiDrive), and lastly you can just tap on the icon at the bottom right side of the screen, followed by the icon and type in the name of the person you wish to begin a chat with. Alternatively, if the person is not an OfficeSuite user you can invite them via the Invite friends icon using a number of sharing options on your device.

After a Chat has been started you can begin sending files by tapping on the Select file icon at the bottom right corner of a specific chat. Doing so will allow you to navigate through your Internal Storage, MobiDrive, Google Drive and Cloud accounts, as well as in FTPs, Local Networks or your default Downloads folder to find the specific document you wish to send.

The upper right corner of the Chat screen holds several important feature for managing your contacts and chats, including:

Search - Using the Search options while in the Chats menu will show chats and documents matching the criteria.
Contextual menu - Tapping this will open a drop-down menu holding two more options, including:
Block list - Here you can view which users have been blocked and unblock them if desired.
Help - Opens this help page.

Additionally, long pressing on a specific chat in the chats list will provide you with option to Delete or Mute it.

A number of other options are available in the upper right corner of the screen once you're in a chat with someone, these include:

Search - Using the Search options while in a Chat will show documents matching the criteria.
Chat Info - Tapping this will provide additional information about the specific chat, as well as several others options to manage it, including:
Add people - Allows you to add more people in the chat. Below this options is a list of the people that are currently in the chat.
Mute Chat - Choose whether to receive notifications for the chat by toggling this option on/off. You can easily enable/disable it with a long press on the specific chat in the chats list.
Leave and delete chat - Leave the current group chat and delete it from your list of currently active chats.
Block - Block a specific user from the chat and stop receiving files and messages from them. When you block a contact they won't be told they've been blocked. If there are group chats in which the blocked contact is present it's advisable you leave those so they cannot send you messages or files.

Additionally, a tap and hold on a document sent in chat will open a drop-down menu featuring a number of further options for it, these include:

Send - Provides the option to send the document to another OfficeSuite user.
Remove from chat - Deletes the file from the current chat.
Save a copy - Will save a copy of the document in your default document downloads folder. The default downloads folder can be changed at any time from the Settings menu.
Add to favourites - Will add the documents to your Favourites list, found in the Recent files menu. Tapping on the icon again will remove the document from the Favourites list.
Show in folder - Will open the folder the document is stored in.
Properties - Will provide you with detailed information about the document, such as Location, Type, Size, as well as when it was Created and Modified. Additionally, at the bottom you can view who has access to the file and change as needed.

A PDF can be secured with several types of passwords. The contents of a secured PDF are encrypted and can be visualized and changed only if the correct password is entered. PDF security settings also include a set of permissions that are applied when a PDF has restricted access.

PDFs support two passwords as follows:

  • PDF open password – When this password is supplied the PDF is opened in restricted mode and the specified permissions are applied.
  • Full access password – This password provides full access to the PDF and allows all visualization and modification functions. Note: the functions available on a particular PDF may be restricted by other protection features, e.g. digital signatures.

If the PDFs open password field is empty, it is opened in restricted mode without requesting a password. If the full access password field is empty, the PDF open password provides full access.

PDF permissions consist of three sets of actions: printing, changing PDF contents, and extraction of text and other data. These permissions are applicable if a separate full access password is available and the PDF is opened in restricted mode.

PDF security settings include an option to disable encryption of the PDF metadata. Leaving the metadata unencrypted allows you to find the PDF by certain search engines based on the metadata contents without the needing to know the PDFs passwords.

The Protect dialog also allows you to select the encryption algorithm and key size out of the standard options supported by the PDF format.

Working with Digital Signatures

Digital signatures provide additional protection functions that are aimed to ensure the integrity and timeliness of the PDF. The physical content of the PDF that is signed cannot be changed without invalidating the signature. If signature permissions allow, a signed PDF can still be modified using an incremental update, but these modifications are clearly identifiable and the original PDF content can always be restored. PDFs signing in this way represent PDF revisions. The PDF may contain multiple consecutive revisions each protected by its own signature.

In addition to integrity protection, it is also possible to determine if certain PDF revisions existed before a specified time. This is done by embedding a digital timestamp in the PDF; a special type of digital signature created by a trusted timestamp authority accessible through the network.

Validation of digital signatures and adding new signatures to a PDF requires access to the corresponding certificates and private keys which should be located on the mobile device. On Android the certificates and private keys are stored in the special Trusted Credential Storage. Android version 4.0 or later performs signatures validation and addition those done by OfficeSuite's PDF Viewer.

Displaying and Validating Digital Signatures

The Signatures dialog displays all available signatures in the order they are added in the PDF (the oldest at the top of the dialog). The signatures are presented with their most important attributes (type, status, signer, signing time, etc.). Each signature item has an overflow menu that allows you to see the signature details, open the PDF revision related to the signature or go to the corresponding signature field in the PDF if it is visible. If you choose to display a PDF revision related to a signature, the OfficeSuite PDF Viewer opens it in read-only mode with limited functions available. It does, however, allow you to save the revision as a new PDF file which can be later on opened in read-write mode with all functions enabled.

Embedded digital signatures are not validated by default as validation may take significant time. The validation may be started by pressing the Validate button in the Signatures dialog. Signature validation is a comprehensive procedure based on the standards and recommendations of IETF and ETSI. It includes the following validation steps for each signature:

  1. Validate the signing digest including decoding the digest with the signing certificate public key, calculating a new digest from the signed content and comparing the decoded and the newly derived digests.
  2. Validate the signing certificate (see details below).
  3. Validate the embedded timestamp (if any) including steps 1 and 2 for the timestamp digest and the timestamp certificate.
  4. Validate the modifications of the PDF after it was signed to ensure that they are allowed by the signature permissions.

The Signatures Details dialog displays the detailed information for the signature and the results of the above validation steps if the validation was performed.

Signing Certificate Validation

The validation of the signing certificate is the most complicated part of the signature validation process. Certificates are usually issued by Certificate Authorities and are signed with the CA private key. In order to validate the certificate signature, it is necessary to have the certificate of the CA. Often the CA is an intermediate authority and its certificate is also signed by another CA. Thus, it is necessary to build the complete certificate chain up to the root CA which has a self-signed certificate. The signing certificate including the public key is embedded in the signature data in the PDF. However, the CA certificates may or may not be available in the signature data. If the CA certificates are not available in the PDF they should be present in the Android Trusted Credential Storage (TCS). The root certificate should always be found in TCS (even if it is available in the PDF) in order to ensure that the whole chain can be trusted. Android has pre-installed many CA certificates in TCS which belong to global security providers. These certificates are trusted by default. You are allowed to add new CA certificates to TCS, but you should do this only for certificates that you really trust. It is also possible to deny some of the pre-installed CA certificates if you do not trust them (see Android help for details).

When the certificate chain is built each certificate in the chain is validated based on its attributes. The validation includes checking of certificate purpose, time validity, extensions, constraints, etc. In addition, a special check is performed of the certificate revocation status. The Certificate Authority that issued the certificate may revoke it if the certificate private key is compromised for some reason. The CAs provide the so-called Certificate Revocation Lists (CRL) or other online interfaces to check for revoked certificates. The revocation verification information may be embedded in the signature data. If it is not available or it is expired the revocation check needs to be performed online. Therefore, in general, the mobile device must have an Internet connection in order to accomplish the revocation check.

The certificate details as well as the results of the certificate validation are displayed in the Certificate Details dialog. This dialog is opened if you follow the links from the certificate chain displayed in the Signatures Details dialog. The dialog contains a Trust button which is enabled if the certificate belongs to a CA. This button allows you to add certificates extracted from the signature data in the PDF to the Trusted Credential Storage. In particular this function can be used to add the certificate chain root to TCS if it is not there but you trust it. This would be necessary to complete the signature validation without errors.

Time Validation of Digital Signatures

Some elements of the digital signatures (e.g. the certificates and the certificates revocation verification information) are valid within a specified time range. Therefore, the validity of the whole digital signature depends on the moment of time for which the validity is checked. The OfficeSuite PDF Viewer follows the ETSI recommendations for determining the validity check time. In general, the validation of the signatures is made related to the current time. In this case the certificates verification information stored in the PDF is irrelevant and fresh verification information is obtained from the certificate issuer.

However, if the PDF contains timestamp signatures or timestamps embedded in other types of signatures, these timestamps provide secure time anchors which allow the PDF Viewer to perform the validation earlier. In this case the PDF Viewer tries to use the verification information stored in the PDF in case it is protected by a timestamp. In more detail, the validation procedure is as follows:

  1. The "latest" PDF timestamp and all later signatures are validated at the current time with verification information collected at the current time. If the PDF does not contain timestamps all signatures are validated at the current time.
  2. The "inner" PDF signatures (including "inner" timestamps) are validated at the time of the previous valid PDF timestamp that encompasses the necessary verification information. If the verification information is not available or is invalid the validation is done at the current time as described above.

PDF timestamps protect the elements with restricted time validity from expiration. In order to provide such protection a particular timestamp should also be valid. The Certificate Details dialog informs you if the corresponding certificate has the necessary verification information stored in the PDF and is protected by a valid timestamp. Protection of the time-dependent signature elements with timestamps allows long-term validity of the PDF digital signatures.

Managing Signature Profiles

Creating and adding new digital signatures to a PDF requires setting of several parameters including selecting a client certificate with a private key, setting permissions, providing a timestamp server URL, etc. Often the same parameters are used when creating multiple signatures. In order to make the signing faster and simpler the OfficeSuite PDF Viewer allows you to create in advance signature profiles with the most frequently used combinations of parameters. A signature profile may be then applied to create a new signature without needing to enter all parameters.

The Signature Profiles dialog is opened by the Profiles item of the Protect menu. The dialog lists the available profiles grouped by signature type ("Certify", "Sign" and "Timestamp") and allows you to edit, copy, rename or delete existing profiles as well as add new profiles of the corresponding type. The profiles are uniquely identified by type and name. The parameters of the profiles from the different types match the parameters available when adding a signature from the corresponding type (excluding the parameters that are dependent on the particular PDF and may not be predefined in a profile).

Adding Signatures to a PDF

The OfficeSuite PDF Viewer provides three items in the Protect menu (CertifySign and Timestamp) to add the corresponding signature type to the current PDF. When any of these items is selected a dialog is opened which allows you to select a pre-defined signature profile of the selected type. Press the Show details button to see the detailed parameter values and change them if necessary.

The detailed parameters for the different signature type are described below. Not all parameters are available for each signature type.

  • Certificate (required for Certify and Sign types). Used to select a client certificate with private key to sign the PDF content digest.
  • Digest algorithm (required). Used to select the digest algorithm that will be used to calculate the PDF content digest.
  • Reason (optional). Used to provide the reason for signing the PDF.
  • Signer's name (optional). Used to provide the name of the person or entity signing the PDF.
  • Location (optional). Used to provide the location of signing.
  • Contact information (optional). Used to provide contact information of the person or entity signing the PDF.
  • Add timestamp and Timestamp server URL (required for Timestamp type). Used to add a timestamp to the signature. The timestamp server with the specified URL should conform to IETF standard RFC 3161 Timestamp Protocol (TSP).
  • Add verification info (optional). Used to add the certificate revocation verification information to the signature data.
  • Allowed changes after signing (required for Certify type). Used to select what changes are allowed in the certified PDF.
  • Lock PDF after signing (optional). Used to specify that the PDF will be locked after signing, i.e. no further modifications will be allowed.
  • Lock fields after signing (optional). Used to specify action for locking of PDF form fields in the signed PDF. The available options are "None" (no fields will be locked), "All" (all fields will be locked), "Include" (only selected fields will be locked) and "Exclude" (all except the selected fields will be locked).
  • Selected fields (optional). Used to select the fields the will be included to or excluded from locking if "Include" or "Exclude" action is selected in the previous parameter.

Ensure Long-term Validity of the Digital Signatures

As described in the Time validation of digital signatures section certain elements of a digital signature have restricted time validity. If they expire the whole signature will be invalidated. To avoid this, all necessary verification information should be included in the signature data and it should be protected by a timestamp. The following actions should be accomplished when adding a new signature:

  1. The complete chain of the signing certificate should be added to the PDF. This is done automatically by the OfficeSuite PDF Viewer.
  2. The certificate revocation verification information for all certificates should be added to the PDF. In order to do this you should check the Add verification info parameter. Note that this action can increase significantly the signature data and the signed PDF respectively.
  3. Add an embedded timestamp to the signature or a separate timestamp signature immediately after the signing.

The above procedure ensures the validity of the added signature until the protective timestamp is valid.

Adding Certificates and Private Keys to the Trusted Credential Storage

The Trusted Credential Storage (TCS) is an Android secure store for CA certificates and client certificates with private keys. The options for TCS management can be found in the Android Security Settings under the Credential Storage heading (the exact location and option names may vary depending on the Android version). The Trusted Credential Storage contains many pre-installed certificates which belong to global security providers. The new certificates are installed using the Install from internal storage option. When this option is selected a file browser window is opened which allows you to choose the files containing the certificates to be installed. (Some Android versions may require that the files are located in the root of the device internal storage or external SD card.) The following types of certificates can be added to TCS:

  • Certificates of Certificate Authorities. The acceptable files have .crt or .cer extension and should be internally marked as CA certificates.
  • Client certificates with private keys. The acceptable files have .pkx or .p12 extension and should contain a private key in addition to the client certificate. The files may optionally contain CA certificates which will be also installed.

The installed CA certificates can be reviewed using the Trusted credentials option of the Android Security Settings. Note that the client certificates are not shown in the Trusted Credentials view. However if the installation is successful they will be available in the corresponding signature dialogs of the OfficeSuite PDF Viewer.

Note: When you try to add a new certificate to the Trusted Credential Storage the Android system may ask you to set a secure screen lock (e.g. pattern, PIN or password) if such a lock is not already set. This is necessary to ensure that your certificates have enough protection if your device is lost or physically accessed without your permission.

Troubleshooting the Digital Signatures Handling

Validation of the digital signatures and addition of new signatures involve complicated procedures which may fail due to different reasons. If you experience errors during signature validation or addition, please make sure that the following conditions are met:

  • The mobile device has an Internet connection.
  • The correct date and time are set.
  • The necessary CA certificates are available in the Android Trusted Credential Storage.
  • The timestamp server URL (when trying to add a timestamp) is valid.
  • The PDF permissions allow the corresponding operation.

As an interface that relies heavily on touch input, the navigation instructions provided in this section are invaluable to getting the most out of OfficeSuite.

All OfficeSuite modules take after Office software applications on desktop PC's in their interface and presentation, consisting of multiple tabs which house different options depending on the document you've opened. Some options are found in multiple tabs, to minimize the need to switch between tabs.

Selecting text is done by double-tapping on the text field, and then dragging the bounding boxes to select the text you wish to manipulate. To select text in Viewer mode of the Document Editor, simply press-and-hold on the relevant text field.

Contextual menus will appear for many items once they have been selected, with different options depending on the type of document. These options include:

Cut the selected text for pasting.
Copy the selected text for pasting.
Paste cut or copied text.
Lookup the text using a downloaded MobiSystems dictionary or reference.
Web Lookup the selected text on the Internet.

Pinch gestures are supported throughout all modules to change the zoom level.

As of Android 7.0, you can now Drag-and-drop elements between OfficeSuite modules that are open in split-screen mode.
