RSA Security 5 manual Format of info supplied to BGetAlgorithmInfo

AI_PKCS_OAEP_RSAPrivate

hashFuncParams.len = 0; hashFuncParams.data = NULL_PTR maskGenFuncParams.len = 0; maskGenFuncParams.data = NULL_PTR maskGenFuncUnderlyingAlgParams.len = 0; maskGenFuncUnderlyingAlgParams.data = NULL_PTR

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:

pSourceParams.len = 0; pSourceParams.data = NULL_PTR;

Format of info supplied to B_GetAlgorithmInfo:

NULL_PTR.

Crypto-C procedures to use with algorithm object:

B_DecryptInit, B_DecryptUpdate, and B_DecryptFinal. You may pass

(B_ALGORITHM_OBJ)NULL_PTR for the randomAlgorithm argument in B_DecryptUpdate and B_DecryptFinal.

Algorithm methods to include in application's algorithm chooser:

AM_RSA_CRT_DECRYPT or AM_RSA_CRT_DECRYPT_BLIND for decryption.

AM_RSA_CRT_DECRYPT_BLIND performs blinding to protect against timing attacks, whereas AM_RSA_CRT_DECRYPT does not. AM_SHA is required for the default pSource digest function. It is also required for MGF1 as underlying algorithm.

Key info types for keyObject in B_EncryptInit or B_DecryptInit:

KI_RSA_CRT, KI_PKCS_RSAPrivate, or KI_PKCS_RSAPrivateBER.

Compatible representation:

AI_PKCS_OAEP_RSAPrivateBER.
