Description copied from interface: PacketCipher

Returns the expected output size for direction and parameters.

Specified by:

getOutputSize in interface PacketCipher

Parameters:

forEncryption - encryption if true

parameters - The cipher parameters

len - the input length.

Returns:

the required minimum output length in bytes.
