Available Encryption Algorithms

The security administrator is responsible for determining the type of encryption to use for a specific tape job data class. The encryption algorithms are associated with a specific key by specifying the Algorithm attribute in the parmlib. CA Tape Encryption supports a variety of encryption algorithms:

• When available, ICSF, CPACF, and the available cryptographic hardware provide the commonly-used standard encryption algorithms that CA Tape Encryption uses.
• CA Tape Encryption uses industry-standard encryption algorithms, including DES, TDES, and AES.
• If the RSA algorithm for public or private key cryptography is available on cryptographic hardware, CA Tape Encryption uses this algorithm when creating B2B tapes. If this algorithm is not available, CA Tape Encryption uses its own implementation of the RSA public domain algorithm.

Note: For detailed information about parameter specifications for these algorithms, see the Configuration Guide.
