Methods
doFinal (Uint8List out , int outOff → int
Finish the operation either appending or verifying the MAC at the end of
the data.
override
getOutputSize (int length → int
inherited
init (bool forEncryption , 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).
noSuchMethod (Invocation invocation → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
prepare (KeyParameter keyParam → void
Prepare for a stream of data. This method is called during
initialization and reset.
process (Uint8List data → Uint8List
Process a whole block of blockSize bytes stored in data at once, returning the result in a
byte array.
inherited
processAADBytes (Uint8List inp , int inpOff , int len → void
Processes the additional authentication data
processBlock (Uint8List inp , int inpOff , Uint8List out , int outOff → int
Process a whole block of data given by inp and starting at offset
inpOff.
override
processBytes (Uint8List inp , int inpOff , int len , Uint8List out , int outOff → int
Process len bytes from inp starting at offset inpOff and output the
result to out at offset outOff.
inherited
reset ()
→ void
Reset the cipher to its original state.
toString ()
→ String
A string representation of this object.
inherited
validateMac ()
→ void
When decrypting, validates the generated authentication tag with the one
in the input stream. When not equal throws InvalidCipherTextException .
This method should be called from the doFinal method.
inherited
Static Properties
factoryConfig → FactoryConfig
Intended for internal use.
