public abstract class Mac extends Object:
Object
└ Mac
Abstract base class for keyed message authentication codes. The primary public HMAC API is exposed through `Hmac`, which binds the MAC to a concrete hash algorithm such as `SHA256()` or `SHA3_512()`. 
import klyn.cryptography

mac as Mac = Hmac(SHA256())
mac.init("secret")
print(mac.doFinal("hello").hex)
Fields
Modifier and Type Member Description
public readonly algorithm
algorithm as String
 Canonical MAC algorithm name.
public readonly hashAlgorithm
hashAlgorithm as String
 Canonical digest algorithm name used by this MAC.

Methods
Modifier and Type Member Description
public doFinal
doFinal(text as String = null) as Digest throws CryptoException:
 Computes the MAC for the buffered text and an optional final chunk.
public static getInstance
getInstance(algorithm as String) as Mac throws CryptoException:
 Compatibility factory for dynamic algorithm selection.
public init
init(key as String, keyEncoding as String = "utf8") as Void:
 Loads the secret key used to compute the MAC.
public reset
reset() as Void:
 Clears the buffered text accumulated with `update`.
public override toString
toString() as String:
 No summary.
public update
update(text as String) as Mac:
 Appends text to the in-memory MAC buffer.
public verify
verify(text as String, expected as String, expectedEncoding as String = "hex") as Boolean throws CryptoException:
 Verifies a MAC value against the provided message.
