Interface PacketEncryption

All Known Implementing Classes:

AESEncryption

public interface PacketEncryption

An interface for encrypting packets. The outputLength should always be the same as the inputLength. This is because that's what the Minecraft vanilla protocol does.

Method Summary

Modifier and Type	Method	Description
void	decrypt(byte[] input, int inputOffset, int inputLength, byte[] output, int outputOffset)	Decrypts the given data.
void	encrypt(byte[] input, int inputOffset, int inputLength, byte[] output, int outputOffset)	Encrypts the given data.
