c-tree's advanced encryption uses a master encryption key to encrypt the following items using the AES cipher:

  1. The security resource in c-tree data and index files that use advanced encryption, and
  2. The encryption key in the transaction log file header when using advanced log encryption.

The length of the master key was increased from 128 bits to 256 bits. FairCom DB can still access files that created with the previous 128-bit master key. This keyword reverts to the original 128-bit master key usage for encryption.

Attempting to open a file created using a 256-bit master key fails with error ENCK_ERR (952) when 256-bit key support is disabled.
