(Unicode C) HMAC MD5 to Match RFC 2022 Test Vectors
Demonstrates using Chilkat in Unicode C to computer HMAC MD5 message authentication codes to match the test vectors given by RFC 2202.
#include <C_CkCrypt2W.h>
void ChilkatSample(void)
{
HCkCrypt2W crypt;
const wchar_t *mac;
// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
crypt = CkCrypt2W_Create();
// The output will be Hex, so set the EncodingMode:
CkCrypt2W_putEncodingMode(crypt,L"hex");
// Set the hash algorithm:
// Choices are: md5, sha-1, sha256, sha384, sha512, md2, haval
CkCrypt2W_putHashAlgorithm(crypt,L"md5");
// Set the HMAC key:
CkCrypt2W_SetHmacKeyEncoded(crypt,L"0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b",L"hex");
