DecryptDataP(3)DecryptDataP(3)NAMEDecryptDataP - Decrypt data with privilege (CDSA)
SYNOPSIS
# include <cdsa/cssm.h>
CSSM_RETURN CSSMAPI CSSM_DecryptDataP (CSSM_CC_HANDLE CCHandle, const
CSSM_DATA *CipherBufs, uint32 CipherBufCount, CSSM_DATA_PTR ClearBufs,
uint32 ClearBufCount, uint32 *bytesDecrypted, CSSM_DATA_PTR RemData,
CSSM_PRIVILEGE Privilege)
LIBRARY
Common Security Services Manager library (libcssm.so)
PARAMETERS
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 priv‐
ilege 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 repre‐
sent an error condition.
ERRORS
Errors are described in the CDSA technical standard. See
CDSA_intro(3). CSSMERR_CSP_BLOCK_SIZE_MISMATCH CSSMERR_CSP_OUT‐
PUT_LENGTH_ERROR
