8 Before You Deploy PGP Viewer for ios About the Configuration File Each PGP Viewer user must have an existing account on your organization's PGP Universal Server. This is the email account that they configure on their Windows device so that they can download encrypted messages. You need to provide the information they require so they can configure this account on their Windows device. If they do not know how to configure an email account on an Windows device, you may have to assist them.. Your organization's PGP Universal Server must have the LDAP Directory Synchronization feature enabled. This feature allows your PGP Viewer user to authenticate to your organization's PGP Universal Server using the authentication credentials on the LDAP server. Each PGP Viewer user must have an existing account on your organization's LDAP server and know the password for their account. Even if your users are configuring PGP Viewer using a configuration file, they will need to know their LDAP password to authenticate to the PGP Universal Server. About the Configuration File Creating and providing a configuration file to your PGP Viewer users helps those users to configure PGP Viewer, and they do not have to enter any information during the configuration process except their LDAP account and proxy server passwords. The configuration file must be able to be opened by PGP Viewer, so it should be named as a file name similar to enroll.pgp. The fields in the PGP Viewer configuration file are: pgpstamp: The fully qualified domain name or IP address of your organization's PGP Universal Server. LDAPUserName: The user name of the PGP Viewer user on your organization's LDAP server. useproxyserver: This value is true if your PGP Viewer users connect to your organization's PGP Universal Server via a proxy server; False if they do not. proxyserverhostname: The fully qualified domain name or IP address of the proxy server.

Your PGP Viewer for ios users will have to install PGP Viewer for ios from the App Store. Refer to the PGP Viewer for ios User's Guide for detailed installation instructions. About Configuration After installation, PGP Viewer must be configured so that your users can enroll with your organization's PGP Universal Server. Your PGP Viewer users must provide the following configuration information: The PGP Universal Server they want to enroll with. Who they are.

Before You Deploy PGP Viewer for ios About Keys 11 Once this information is provided, users are enrolled and your organization's PGP Universal Server downloads the appropriate policies to the user's Windows device. There are three ways to configure PGP Viewer and enroll with a PGP Universal Server: Using a configuration file. The configuration file provides all of the information your PGP Viewer users need to enroll, except for the password to their LDAP account. Passwords should never be stored unencrypted in a configuration file. Your PGP Viewer users need to enter the password to their LDAP account to complete the process. Manually entering required information, by using a direct connection to your organization's PGP Universal Server. In this case, your PGP Viewer users must manually enter the required configuration information on their Windows device. Manually entering required information, by connecting to your organization's PGP Universal Server using a proxy server. In this case, your PGP Viewer users must manually enter the required configuration information plus the information about your organization's proxy server on their Windows device. Refer to the PGP Viewer for ios User's Guide for detailed configuration instructions. About Keys PGP Viewer for ios itself does not create PGP keys, but it uses them to decrypt encrypted messages and to verify signatures (if this feature is enabled). In the case of SKM keys, if the key does not exist on the PGP Universal Server, PGP Viewer sends a request to the PGP Universal Server to create the key for the user. PGP Viewer for ios supports all four modes in which a PGP keypair can be created: Server Key Mode (SKM). The private key is stored unencrypted on the PGP Universal Server. SKM keys for a PGP Viewer user are automatically downloaded to their Windows device when they enroll. Your users do not need to do anything else other than enroll to use their key. Guarded Key Mode (GKM). The private key is stored encrypted on the PGP Universal Server. GKM keys for a PGP Viewer user are also automatically downloaded to the user's Windows device when enrolling. The user is required to enter the passphrase to their private key in order to use it. Client Key Mode (CKM). The private key is stored encrypted on a PGP client, such as PGP Desktop. To use a CKM key with PGP Viewer, the keypair must be saved to a key file and emailed and retrieved on the Windows device. When received, the user must open the emailed attachment using PGP Viewer and provide the passphrase to the private key. The key is then imported into PGP Viewer and is ready for use. Refer to the PGP Viewer for ios User's Guide for detailed instructions about importing a CKM key. Server Client Key Mode (SCKM). The key is generated on a PGP client, such as PGP Desktop. Private encryption subkeys are stored both on the client and on the PGP Universal Server while private signing subkeys are stored only on the client. To use an SCKM key with PGP Viewer, the keypair must be saved to a key file and emailed to and retrieved on the Windows device. When received, the user must open the emailed attachment using PGP Viewer and provide the passphrase to the private key. The key is then imported into PGP Viewer and is ready for use.

12 Before You Deploy PGP Viewer for ios About Keys Refer to the PGP Universal Server Administrator's Guide for more information about PGP key modes. Refer to the PGP Viewer for ios User's Guide for the procedure for downloading keys onto an Windows device for use with PGP Viewer.

3 Deploying PGP Viewer for ios PGP Viewer for ios is currently available only through the Apple App Store. Your PGP Viewer for ios users must install the app using the Apple App Store.

4 Assisting Your PGP Viewer for ios Users There are a number of things that PGP Corporation recommends you do to help support your PGP Viewer for ios users: Provide your PGP Viewer users with a written statement about appropriate uses for PGP Viewer. Include a summary of your official corporate security policies and how they can use PGP Viewer to conform to those policies. You might want to include, for example, whether or not they are allowed to include decrypted text in replies to messages that the received encrypted and whether they can use corporate email on their Windows device if they do not use PGP Viewer. Make sure they get a copy of the PGP Viewer for ios User's Guide. Strongly encourage them to read the user's guide before installing PGP Viewer on their Windows devices. Tell them about the other resources that are available to them, including the on-device help and any assistance your organization provides. Give them a phone number to call or an email address to write to in case they experience problems. Set up a system so that each user can report a successful installation.

5 The End-User Experience You can help ensure a successful end-user experience with PGP Viewer for ios by preparing your end users for the installation, configuration, and usage of PGP Viewer. If you decide to provide your PGP Viewer users with a document created by your organization, you may want to include some or all of the points listed here. In This Chapter During the Installation Process...17 During the Configuration Process...17 During Normal Usage...18 During the Installation Process The following items may impact your PGP Viewer users during installation: Your PGP Viewer for ios users must get the PGP Viewer installer from the appropriate app store. If they are not very familiar with the app store and/or how to install Windows apps, they may need assistance. During the Configuration Process The following items may impact your PGP Viewer users during the configuration process: If their account on your organization's PGP Universal Server is not correctly set up, then your PGP Viewer users will be able to install PGP Viewer for ios correctly, but they will not be able to configure it correctly or get it to work. Make sure: Each PGP Viewer user has a managed account on your organization's PGP Universal Server. Your organization's PGP Universal Server has the LDAP Directory Synchronization feature enabled. Each PGP Viewer user has an account on the LDAP directory and knows his or her authentication credentials. If access to your organization's PGP Universal Server is through a proxy server, notify your PGP Viewer users that must manually configure the proxy server information and inform them that they need to enter this information during configuration.

18 The End-User Experience During Normal Usage Notify those PGP Viewer users who will have to download their key to their Windows device manually that they need to do this. This applies to PGP Viewer users whose PGP key is Client Key Mode (CKM) or Server Client Key Mode (SCKM). During Normal Usage The following items may impact your PGP Viewer for ios users during normal usage: Encrypted messages they receive will not be readable. Depending on the format of the message, they may see attachments, encrypted text, or attachments and encrypted text where they are expecting the body of the message. They need to know that this is the type of message that is opened by PGP Viewer. Encrypted messages are not opened directly by PGP Viewer; instead, your PGP Viewer users must open the encrypted message first and then take the appropriate action to read the text based on the format of the encrypted message. PGP Viewer functionality may change from time to time if the policies change that apply to a user.
