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.

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
dataat once, returning the result in a byte array.inherited -
processBytes(
Uint8List? inp, int inpOff, int len, Uint8List? out, int outOff) → void -
Process
lenbytes of data given byinpand starting at offsetinpOff. The resulting cipher text is put inoutbeginning at positionoutOff.override -
reset(
) → void -
Reset the cipher to its original state.
override
-
returnByte(
int inp) → int -
Process one byte of data given by
inpand return its encrypted value.override -
toString(
) → String -
A string representation of this object.

Operators
-
operator ==(
Object other) → bool -
The equality operator.
