Detailed Description

Implemenation of encryption for UDP trafic

Member Function Documentation

Encrypt() [1/2]

void Photon.SocketServer.Security.Encryptor.Encrypt ( byte[]  data, int  len, byte[]  output, ref int  offset  )

inline

Encrypts data. puts them into output buffer and prepends with IV

Parameters

data
len
output
offset

Returns

Thread safe. Can be used for inplace encryption

Encrypt() [2/2]

void Photon.SocketServer.Security.Encryptor.Encrypt ( byte[]  data, int  srcOffset, int  len, byte[]  output, ref int  outputOffset  )

inline

Encrypts data. puts them into output buffer and prepends with IV

Parameters

data	incoming data
srcOffset	offset from the begining
len	length of data
output	buffer where to put result
outputOffset	offset in result buffer

Returns

Thread safe. Can be used for inplace encryption

EncryptedDataSize()

static int Photon.SocketServer.Security.Encryptor.EncryptedDataSize ( int  dataLen )

inlinestatic

EncryptedDataSizeWithIV()

static int Photon.SocketServer.Security.Encryptor.EncryptedDataSizeWithIV ( int  dataLen )

inlinestatic

FinishHMAC()

byte [] Photon.SocketServer.Security.Encryptor.FinishHMAC ( byte[]  data, int  offset, int  count  )

inline

Finishes current HMAC. can be used for HMAC calculation if all data are in same buffer

Parameters

data	buffer with data
offset	offset in buffer
count	count byte to use from buffer

Returns

calculated HASH

FinishHMACThreadSafe()

byte [] Photon.SocketServer.Security.Encryptor.FinishHMACThreadSafe ( byte[]  data, int  offset, int  count  )
