Example HMAC Using HMACSHA256
hmac( "msg", "secret", "HMACSHA256" );
Result: fe4f9c418f683f034f6af90d1dd5b86ac0355dd96332c59cc74598d0736107f6
Additional Examples
message = "this is a test";
key = "ABC123";
// Using the required fields only
result = HMAC( message, key );
writeDump( result ); // 776770430C93778AD6F91B43A4A30B69
// Using the optional algorithm parameter (HmacSHA1)
algorithm = "HmacSHA1";
result = HMAC( message, key, algorithm );
writeDump( result ); // 049E53BAE339C4A05587D7BBBA2857548E8FC327
// Using the optional algorithm parameter (HmacSHA256)
algorithm = "HmacSHA256";
result = HMAC( message, key, algorithm );
writeDump( result ); // 0503949602EDE3FF61C84F4CE51C99EEA2961CAA144AEE552F7D120AD6A60D7D
// Using the optional encoding parameter (UTF-8)
encoding = "UTF-8";
result = HMAC( message, key, algorithm, encoding );
writeDump( result );
