(C#) HMAC MD5 to Match RFC 2022 Test Vectors

Demonstrates using Chilkat in C# to computer HMAC MD5 message authentication codes to match the test vectors given by RFC 2202.

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

Chilkat.Crypt2 crypt = new Chilkat.Crypt2();

// The output will be Hex, so set the EncodingMode:
crypt.EncodingMode = "hex";

// Set the hash algorithm:
// Choices are: md5, sha-1, sha256, sha384, sha512, md2, haval
crypt.HashAlgorithm = "md5";

string mac;

// Set the HMAC key:
crypt.SetHmacKeyEncoded("0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b","hex");
mac = crypt.HmacStringENC("Hi There");
Debug.WriteLine(mac);

crypt.SetHmacKeyEncoded("Jefe","ansi");
mac = crypt.HmacStringENC("what do ya want for nothing?");
Debug.WriteLine(mac);
