VMS Help ENCRYPT, Qualifiers, /DATA_ALGORITHM *Conan The Librarian |
{ DESCBC (default) }
/DATA_ALGORITHM= { AESmmmkkk }
{ }
Where mmm is the mode CBC, ECB, CFB, or OFB; and kkk is 128,
192, or 256 bits. Cipher Block Chaining (CBC) and Electronic Code
Book (ECB) are 16-byte block modes, meaning blocks are padded to
16 bytes if necessary during encryption. The padding is removed
during decryption. Cipher Feedback (CFB) and Output Feedback
(OFB) are 8-bit character stream mode emulation, useful in data
communications and where no padding is required.
Note that /DATA_ALGORITM=AES is a shortcut for specifying
AESCBC128.
The data algorithm is used with the randomly generated key to
perform encryption of the file's data. When specifying an AES
algorithm, specify both /KEY and /DATA=AESmmmkkk qualifiers and
use an AES created key.
