HMAC with SHA256

See more Encryption Examples

Demonstrates how to compute a HMAC SHA256 keyed-hash message authentication code. Unicode C++

#include <CkCrypt2W.h>

void ChilkatSample(void)
    {
    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    CkCrypt2W crypt;

    // The output will be Hex, so set the EncodingMode:
    crypt.put_EncodingMode(L"hex");

    // Set the hash algorithm:
    // Choices are: md5, sha-1, sha256, sha384, sha512, md2, haval
    crypt.put_HashAlgorithm(L"sha256");
    crypt.put_MacAlgorithm(L"hmac");

    const wchar_t *mac = 0;

    // Set the HMAC key:
    crypt.SetMacKeyEncoded(L"The_API_Secret",L"ascii");
    mac = crypt.macStringENC(L"The quick brown fox jumps over the lazy dog");
    wprintf(L"%s\n",mac);
    }
