Overview

Package arc4 provides multiple implementations of RC4-based socket encryption methods. WARNING: RC4 is widely deemed as UNSAFE by cryptography specialists. We only are providing this package for backward compatibility with existing implementations.

Types

type ARC4

type ARC4 struct {
	S []byte
	// contains filtered or unexported fields
}

func New

func New(key []byte) *ARC4

func (*ARC4) Decrypt

func (this *ARC4) Decrypt(data []byte)

func (*ARC4) Encrypt

func (this *ARC4) Encrypt(data []byte)

func (*ARC4) Next

func (this *ARC4) Next() uint8

type AuthCipher

type AuthCipher struct {
	ServerEncryptionKey []byte
	ServerDecryptionKey []byte
	// contains filtered or unexported fields
}

AuthCipher creates two ARC4 states for sending and recieving. They are created from pre-generated seeds, computed along with the session key.

func (*AuthCipher) Decrypt

func (c *AuthCipher) Decrypt(data, tag []byte) error

func (*AuthCipher) Encrypt

func (c *AuthCipher) Encrypt(data, tag []byte) error

func (*AuthCipher) Init

func (c *AuthCipher) Init(server bool, sessionKey []byte) error

type CipherTBC

type CipherTBC struct {
	// contains filtered or unexported fields
}

CipherTBC implements Vanilla encryption but with an HMAC key.

func (*CipherTBC) Decrypt

func (v *CipherTBC) Decrypt(data, tag []byte) error

func (*CipherTBC) Encrypt

func (v *CipherTBC) Encrypt(data, tag []byte) error

func (*CipherTBC) Init

func (v *CipherTBC) Init(server bool, sessionKey []byte) error

type CipherVanilla

type CipherVanilla struct {
	// contains filtered or unexported fields
}

CipherVanilla implements Vanilla-style encryption (Not ARC4, what even is this?) some kind of basic xor counter cipher

func (*CipherVanilla) Decrypt

func (v *CipherVanilla) Decrypt(data, tag []byte) error

func (*CipherVanilla) Encrypt

func (v *CipherVanilla) Encrypt(data, tag []byte) error

func (*CipherVanilla) Init

func (v *CipherVanilla) Init(server bool, sessionKey []byte) error
