Disk Groups configured to use the original implementation of AES 256 should be migrated to the current AES 256 v2 implementation. 256-bit AES encryption was introduced in OnBase 14 and renamed to AES 256 v1 in OnBase 14 SP 2.
OnBase 13 and earlier clients cannot archive or read documents stored in a 256-bit AES encrypted Disk Group. Before configuring AES 256 v2 make sure all clients and the OnBase Application Server are version 14 SP 2 or higher.
To configure an AES 256 v2 Encrypted Disk Group, the Minimum Client Version must be at least 14.0.2.584 and the Minimum Web Client Version must be at least 14.0.2.128. To configure an AES CFB Encrypted Disk Group, the Minimum Client Version and Minimum Web Client Version must both be at least 18.0.These values are set in the Utils | Version Compatibility dialog box.
