Thanks for the information Jeffrey,
I am having difficulty with the verification, though. Having created
the digest using HashFilter(), I attempted to use
HashVerificationFilter() to verify the generated digest. The code is
below. The output I get from the verification process is "00", which I
guess is "Verification Failed" in Hexadecimal.
Is the digest (i.e sOut in my case) supposed to be the only input to
HashVerificationFilter()? Has anybody been able to successfully verify
a digest?
member_ptr<MessageAuthenticationCode> mac;
std::string decodedKey;
StringSource(hexKey, true, new HexDecoder(new
StringSink(decodedKey)));
mac.reset(new HMAC<SHA1>((const byte *)decodedKey.data(),
decodedKey.size()));
string str("This is a test"); string sOut,sOut2;
StringSource(str, true, new HashFilter(*mac, new HexEncoder(new
StringSink(sOut))));
StringSource(sOut, true, new HashVerificationFilter(*mac, new
HexEncoder(new StringSink(sOut2))));
Thanks!!
