AI_PKCS_OAEP_RSAPublic
150 RSA BSAFE Crypto-C Library Reference Manual
Failure to properly initialize these parameters may cause errors when they are
implemented in future versions of Crypto-C. In this case, the default parameters for
pSourceParams
should be set by the caller as follows:
Format of info supplied to B_GetAlgorithmInfo:
NULL_PTR.
Crypto-C procedures to use with algorithm object:
B_EncryptInit, B_EncryptUpdate, and B_EncryptFinal.
B_EncryptFinal requires a valid random number generator as a B_ALGORITHM_OBJ in
its
randomAlgorithm
argument. PKCS #1 v2.0 does not specify the random number
generation method. It is recommended that
AI_X962Random_V0 or AI_SHA1Random be
initialized with enough seed bytes to produce 160 bits of entropy.
You may pass (
B_ALGORITHM_OBJ)NULL_PTR for the
randomAlgorithm
argument in
B_EncryptUpdate.
Algorithm methods to include in application's algorithm chooser:
AM_RSA_ENCRYPT.
AM_SHA is required for the default
pSource
digest function and also for the default MGF
underlying digest method.
Key info types for keyObject in B_EncryptInit or B_DecryptInit:
KI_RSAPublic or KI_RSAPublicBER.
hashFuncParams.len = 0;
hashFuncParams.data = NULL_PTR
maskGenFuncParams.len = 0;
maskGenFuncParams.data = NULL_PTR
maskGenFuncUnderlyingAlgParams.len = 0;
maskGenFuncUnderlyingAlgParams.data = NULL_PTR
pSourceParams.len = 0;
pSourceParams.data = NULL_PTR;
