class Gibberish::HMAC
Easy to use HMAC
## Example
Gibberish::HMAC256('key', 'data') #=> 5031fe3d989c6d1537a013fa6e739da23463fdaec3b70137d828e36ace221bd0 Gibberish::HMAC1('key', 'data') # SHA1 #=> 104152c5bfdca07bc633eebd46199f0255c9f49d Gibberish::HMAC224('key', 'data') # SHA224 #=> 19424d4210e50d7a4521b5f0d54b4b0cff3060deddccfd894fda5b3b Gibberish::HMAC384('key', 'data') # SHA384 #=> c5f97ad9fd1020c174d7dc02cf83c4c1bf15ee20ec555b690ad58e62da8a00ee 44ccdb65cb8c80acfd127ebee568958a Gibberish::HMAC512('key', 'data') # SHA512 #=> 3c5953a18f7303ec653ba170ae334fafa08e3846f2efe317b87efce82376253c b52a8c31ddcde5a3a2eee183c2b34cb91f85e64ddbc325f7692b199473579c58
## OpenSSL CLI Interop
echo -n "stuff" | openssl dgst -sha256 -hmac 'password'
is the same as
Gibberish::HMAC256('password', 'stuff')
