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.
