tenduke::crypto::MessageDigestVerifier Class Reference

#include <MessageDigestVerifier.h>

Detailed Description

Verifies a message by computing digest for the message and comparing the computed signature to the provided signature.

The digest could be a cryptographic hash function, message authentication code (MAC), or a signature.

NOTE: Instances are not thread safe.

NOTE: Most implementations throw tenduke::crypto::CryptoException if construction fails.
