CBCBlockCipherMac class

standard CBC Block Cipher MAC - if no padding is specified the default of pad of zeroes is used.

Constructors

CBCBlockCipherMac(BlockCipher cipher, int macSizeInBits, Padding? padding)

create a standard MAC based on a block cipher with the size of the MAC been given in bits. This class uses CBC mode as the basis for the MAC generation.

CBCBlockCipherMac.fromCipher(BlockCipher cipher)

create a standard MAC based on a CBC block cipher. This will produce an authentication code half the length of the block size of the cipher.

CBCBlockCipherMac.fromCipherAndMacSize(BlockCipher cipher, int macSizeInBits)

create a standard MAC based on a block cipher with the size of the MAC been given in bits. This class uses CBC mode as the basis for the MAC generation.

CBCBlockCipherMac.fromCipherAndPadding(BlockCipher cipher, Padding? padding)

create a standard MAC based on a CBC block cipher. This will produce an authentication code half the length of the block size of the cipher.

Properties

algorithmName → String

Get this algorithm's standard name.

no setter, override

hashCode → int

The hash code for this object.

no setter, inherited

macSize → int

Get this MAC's output size.

Methods

doFinal(Uint8List out, int outOff) → int

Store the MAC of previously given data in buffer out starting at offset outOff. This method returns the size of the digest.

override

init(CipherParameters params) → void

Init the MAC with its initialization params. The type of CipherParameters depends on the algorithm being used (see the documentation of each implementation to find out more).

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

process(Uint8List data) → Uint8List

Process a whole block of data at once, returning the result in a new byte array.

inherited

reset() → void

Reset the mac generator.

override

toString() → String

A string representation of this object.

inherited

update(Uint8List inp, int inOff, int len) → void

Add len bytes of data contained in inp, starting at position inpOff to the MAC'ed input.

override

updateByte(int inp) → void

Add one byte of data to the MAC input.

override

Operators

operator ==(Object other) → bool

The equality operator.
