CSSM_DecryptDataUpdate z/OS Open Cryptographic Services Facility Application Programming SC24-5899-01 |
|
PurposeThis function updates the staged decrypt function. The CSSM_QuerySize function can be used to estimate the output buffer size required for each update call. There may be algorithm-specific and token-specific rules restricting the lengths of data in CSSM_DecryptDataUpdate calls. When working with U.S. exportable versions of the OCSF, the caller may be required to possess specific exemptions or privileges in order to allow this call to complete successfully. Format
ParametersInput
Output
Return ValueCSSM_OK if the function was successful. CSSM_FAIL if an error occurred. Use CSSM_GetError to determine the exact error. NotesThe output can be obtained either by filling the caller-supplied buffer or using the application's memory allocation functions to allocate space, which the application must later free. If the output buffer pointer is NULL, an error code CSSM_CSP_INVALID_DATA_POINTER is returned. In-place decryption can be done by supplying the same input and output buffers.
