Cryptography Service Provider (CSP) API

The HP Praesidium worldwide exportable and HP Praesidium Strong Encryption CSPs

support all functions and algorithms described in this section (only with larger available key

sizes). In addition, both CSPs support the DES algorithm. See the CSP manpage for speciﬁc

details.
