z/OS User Exits › z/OS Server User Exits—CICS › TIRDCRYX—Server Decryption Exit › Purpose

Purpose

TIRDCRYX is called by the Server Manager after it detects that the client has sent an encrypted cooperative buffer. The user is responsible for decrypting the area pointed to by DATA-BUFFER-PTR for the length BUFFER-SIZE bytes. Maximum size of the decrypted data cannot exceed DECRYPTION-MAX-SIZE.

Note: Encryption/decryption of the request and response cooperative buffers are mutually exclusive - encryption/decryption of the request buffer does not necessitate that the same be done to the response buffer and vice-versa.
