(CSSM_CC_HANDLE CCHandle,
const CSSM_DATA *CipherBufs,
uint32 CipherBufCount,
CSSM_DATA_PTR ClearBufs,

LIBRARY

Common Security Services Manager library (cdsa$incssm300_shr.exe)

PARAMETERS

Privilege (input)
  

The privilege to be applied during the cryptographic operation.

See CSSM_DecryptData() for other parameters.

DESCRIPTION

This function is similar to CSSM_DecryptData(). It also accepts a USEE tag as a privilege request parameter. CSSM checks that either its privilege set or the application's privilege set (if the application is signed) includes the tag. If the tag is found and the service provider privilege set indicates that it is supported, the tag is forwarded to the service provider.

RETURN VALUE

A CSSM_RETURN value indicating success or specifying a particular error condition. The value CSSM_OK indicates success. All other values represent an error condition.

ERRORS

Errors are described in the CDSA Technical Standard.

CSSMERR_CSP_BLOCK_SIZE_MISMATCH
CSSMERR_CSP_OUTPUT_LENGTH_ERROR
