ChaCha20Algorithm class
Constructors
- ChaCha20Algorithm(Uint32List key, int blockCounter, Uint32List nonce)
- Expects a key with 8*32 bit, a 32-bit block-counter and a 3x32 bit nonce
- ChaCha20Algorithm.fromState(Uint32List chaChaState)
Properties
- chaChaState ↔ Uint32List
-
The current state of this ChaCha20 iteration.
getter/setter pair
- hashCode → int
-
The hash code for this object.
no setterinherited
- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
chaCha20(
) → void - Performs the ChaCha20 algorithm
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
processBytes(
Uint8List inputBytes) → Uint8List - Returns a new Uint8List with transformed inputBytes. This can encrypt and decrypt, since they are the same for Chacha20.
-
quarterRound(
int a, int b, int c, int d) → void - Performs a quarter round of ChaCha20 according to the documentation by RFC
-
rotateLeft(
int n, int count) → int - implementation of a left rotation of an integer by count places.
-
tenQuarterRounds(
) → void - ChaCha20 consists of ten of these quarter rounds
-
toString(
) → String -
A string representation of this object.
inherited
-
transformFourInputsByChaChaQuarterRound(
Uint32List fourInputs) → Uint32List - Takes a list of four inputs and performs a ChaCha quarter round on them
Operators
-
operator ==(
Object other) → bool -
The equality operator.
