Key Points

There are two fundamental categories of cryptographic algorithms:

•

Symmetric or secret key

IBM supports the Data Encryption Algorithm for symmetric encryption. The

export of DES is restricted outside the United States and Canada or the

banking industry.

Therefore, IBM also provides Commercial Data Masking Facility (CDMF) as

an exportable limited DES implementation.

•

Asymmetic or public key

IBM supports the Rivest Shamir Adleman (RSA) Public Key Algorithm for

asymmetric encryption.
