Открытые методы

Метод	Описание
AddPayload ( byte buffer ) : void
AddPayload ( byte buffer, int offset, int count ) : void
BeginHandshake ( IConnection socket, AsyncCallback callback, object state ) : IAsyncResult	Begins the message stream encryption handshaking process
BeginHandshake ( IConnection socket, byte initialBuffer, int offset, int count, AsyncCallback callback, object state ) : IAsyncResult	Begins the message stream encryption handshaking process, beginning with some data already received from the socket.
Decrypt ( byte data, int offset, int length ) : void	Decrypts some data (should only be called after onEncryptorReady)
Encrypt ( byte data, int offset, int length ) : void	Encrypts some data (should only be called after onEncryptorReady)
EncryptedSocket ( EncryptionTypes allowedEncryption ) : System
EndHandshake ( IAsyncResult result ) : void

Защищенные методы

Метод	Описание
Combine ( ) : byte[]	Concatenates several byte buffers
CreateCryptors ( string encryptionSalt, string decryptionSalt ) : void	Instantiate the cryptors with the keys: Hash(encryptionSalt, S, SKEY) for the encryptor and Hash(encryptionSalt, S, SKEY) for the decryptor. (encryptionSalt should be "keyA" if you're A, "keyB" if you're B, and reverse for decryptionSalt)
DeLen ( byte data ) : int	Converts a 2-byte big endian integer into an int (reverses operation of Len())
DoDecrypt ( byte data ) : byte[]	Decrypts some data with the RC4 encryptor used in handshaking
DoDecrypt ( byte data, int offset, int length ) : void	Decrypts some data with the RC4 decryptor used in handshaking
DoEncrypt ( byte data ) : byte[]
DoEncrypt ( byte data, int offset, int length ) : void	Encrypts some data with the RC4 encryptor used in handshaking
DoneReceiveY ( ) : void
DoneSynchronize ( ) : void
FillSynchronizeBytes ( bool succeeded, int count, object state ) : void
GeneratePad ( ) : byte[]	Returns a 0 to 512 byte 0-filled pad.
Hash ( ) : byte[]	Hash some data with SHA1
Len ( byte data ) : byte[]	Returns a 2-byte buffer with the length of data
Ready ( ) : void	Signal that the cryptor is now in a state ready to encrypt and decrypt payload data
ReceiveMessage ( byte buffer, int length, AsyncCallback callback ) : void
ReceiveY ( ) : void	Receive the first 768 bits of the transmission from the remote client, which is Y in the protocol (Either "1 A->B: Diffie Hellman Ya, PadA" or "2 B->A: Diffie Hellman Yb, PadB")
SelectCrypto ( byte remoteCryptoBytes, bool replace ) : int	Sets CryptoSelect and initializes the stream encryptor and decryptor based on the selected method.
SendMessage ( byte toSend ) : void
SendY ( ) : void	Send Y to the remote client, with a random padding that is 0 to 512 bytes long (Either "1 A->B: Diffie Hellman Ya, PadA" or "2 B->A: Diffie Hellman Yb, PadB")
SetMinCryptoAllowed ( EncryptionTypes allowedEncryption ) : void
Synchronize ( byte syncData, int syncStopPoint ) : void	Read data from the socket until the byte string in syncData is read, or until syncStopPoint is reached (in that case, there is an EncryptionError). (Either "3 A->B: HASH('req1', S)" or "4 B->A: ENCRYPT(VC)")

Приватные методы

Метод	Описание
DoneReceive ( bool succeeded, int count, object state ) : void
DoneSend ( bool succeeded, int count, object state ) : void
GenerateX ( ) : void	Generate a 160 bit random number for X
GenerateY ( ) : void	Calculate 2^X mod P
RandomNumber ( int max ) : int
