I am using MS_ENH_RSA_AES_PROV provider with PROV_RSA_AES provider type. I have selected CALG_AES_128 block cipher algorithm with CRYPT_MODE_CFB cipher mode. I would like to set KP_MODE_BITS key parameter to 128, but calling CryptSetKeyParam() by passing value greater than 64 always returns with NTE_BAD_DATA (0x80090005L).
How can I set CFB-128 using CryptoAPI? Thanks.
