The following ICSF functions are called by Authentication Suite Server SDK to perform the encryption and decryption of the sensitive BLOB data:

  • CSNBKRR2. Reads a named ICSF CKDS record.
  • CSNBENC. Performs a triple DES encryption (CBC mode).
  • CSNBDEC. Performs a triple DES decryption (CBC mode).
  • CSNBRNGL. Performs Random Number Generation.
  • CSNBSAE. Performs AES encryption (CBC mode).
  • CSNBSAD. Performs AES decryption (CBC mode).

You might need to authorize the use of these functions if they have been protected through the RACF class CSFSERV or any equivalent resource security mechanism.
