Message Authentication Codes

MAC
Mac mac(Key key, String algorithm);
Returns an interface for producing message authentication codes.
Usage Example
KeyStore keystore = keystore("classpath:/keystore.p12", "password".toCharArray(), "PKCS12");
Key key = secretKey(keystore, "hmac", "password".toCharArray());
​
Mac alice = mac(key, "HmacSHA1");
Mac bob = mac(key, "HmacSHA1");
​
byte[] message = "Hello there".getBytes(UTF_8);
byte[] aliceMac = alice.get(message);
byte[] bobMac = bob.get(message);
assertArrayEquals(aliceMac, bobMac);
Encoding MAC
EncodingMac mac(
    Key key, 
    String algorithm, 
    Encoding encoding, 
    Charset charset
);
Returns an interface for producing encoded message authentication codes. The character set refers to the plain text message string encoding.
Usage Example
KeyStore keystore = keystore("classpath:/keystore.p12", "password", "PKCS12");
Key key = secretKey(keystore, "hmac", "password");
​
EncodingMac alice = mac(key, "HmacSHA1", BASE64, UTF_8);
EncodingMac bob = mac(key, "HmacSHA1", BASE64, UTF_8);
​
String message = "Hello there";
String aliceMac = alice.get(message);
String bobMac = bob.get(message);
assertEquals(aliceMac, bobMac);
