SICStreamCipher class

Implementation of SIC mode of operation as a StreamCipher. This implementation uses the IV as the initial nonce value and keeps incrementing it by 1 for every block. The counter may overflow and rotate, and that would cause a two-time-pad error, but this is so unlikely to happen for usual block sizes that we don't check for that event. It is the responsibility of the caller to make sure the counter does not overflow.

Properties

algorithmName → String

Get this algorithm's standard name.

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

underlyingCipher → BlockCipher

final

Methods

init(bool forEncryption, covariant ParametersWithIV<CipherParameters?> params) → void

Init the cipher 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 byte array.

inherited

processBytes(Uint8List? inp, int inpOff, int len, Uint8List? out, int outOff) → void

Process len bytes of data given by inp and starting at offset inpOff. The resulting cipher text is put in out beginning at position outOff.

override

reset() → void

Reset the cipher to its original state.

override

returnByte(int inp) → int

Process one byte of data given by inp and return its encrypted value.

override

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.

inherited

Static Properties

factoryConfig → FactoryConfig

Intended for internal use.
