RSA Signing / Verification

XP_CRYPTOAPI provides the following RSA XPís for signing using the RSA public key algorithm: XP_RSA_MD2_SIGN, XP_RSA_MD4_SIGN, XP_RSA_MD5_SIGN, XP_RSA_SHA1_SIGN and XP_DSA_SIGN. The various XPís allow you to specify which hash algorithm is used. The corresponding verification XPís are XP_RSA_MD2_VERIFY, XP_RSA_MD4_VERIFY, XP_RSA_MD5_VERIFY and XP_RSA_SHA1_VERIFY.

DSA Signing / Verification

Unlike RSA, using the DSA signature, the DSS dictates that a SHA1 hash is used to sign the message. This means that there is only one XP for DSA in XP_CRYPTOAPI. It is called XP_DSA_SIGN. The corresponding verification XP is XP_DSA_VERIFY.
