Hmac

Creates an algorithmic hash of an object

Method Signature

Hmac(input=[any], key=[any], algorithm=[string], encoding=[string], numIterations=[integer])

Arguments

Argument	Type	Required	Description	Default
input	any	true	The item to be hashed
key	any	true
algorithm	string	false	The supported {@link java.security.MessageDigest} algorithm (case-insensitive)	HmacMD5
encoding	string	false	Applicable to strings ( default "utf-8" )	utf-8
numIterations	integer	false		1

Examples

Example HMAC Using HMACSHA256

Run Example

hmac( "msg", "secret", "HMACSHA256" );

Result: fe4f9c418f683f034f6af90d1dd5b86ac0355dd96332c59cc74598d0736107f6

Additional Examples

Run Example

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 );
 // 0503949602EDE3FF61C84F4CE51C99EEA2961CAA144AEE552F7D120AD6A60D7D
