Methods

combineLists(Uint8List a, Uint8List b) Uint8List
deriveKey(Uint8List? inp, int inpOff, Uint8List out, int outOff) int
Derive key from given input and put it in out at offset outOff.
override
expandNext() → void
Performs the expand part of the key derivation function, using currentT as input and output buffer.
extract(Uint8List? salt, Uint8List ikm) KeyParameter
Performs the extract part of the key derivation function.
init(covariant HkdfParameters params) → void
Init the derivator 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
toString() String
A string representation of this object.
