bool IsKeySet (void) const
void SetKey (const unsigned char key[16])
 Set the encryption key.
void UnsetKey (void)
 Unset the encryption key.
void Encrypt (unsigned char *input, unsigned int inputLength, unsigned char *output, unsigned int *outputLength, RakNetRandom *rnr)
 Encryption adds 6 data bytes and then pads the number of bytes to be a multiple of 16.
bool Decrypt (unsigned char *input, unsigned int inputLength, unsigned char *output, unsigned int *outputLength)
 Decryption removes bytes, as few as 6.


Detailed Description

Encrypts and decrypts data blocks.

Member Function Documentation

bool DataBlockEncryptor::Decrypt ( unsigned char *  input,
unsigned int  inputLength,
unsigned char *  output,
unsigned int *  outputLength 
)

Decryption removes bytes, as few as 6.

Output should be large enough to hold this. Output can be the same memory block as input

Parameters:
[in] input the input buffer to decrypt
[in] inputLength the size of the input buffer
[in] output the output buffer to store decrypted data
[in] outputLength the size of the output buffer
Returns:
False on bad checksum or input, true on success

void DataBlockEncryptor::Encrypt ( unsigned char *  input,
unsigned int  inputLength,
unsigned char *  output,
unsigned int *  outputLength,
RakNetRandom *  rnr 
)

Encryption adds 6 data bytes and then pads the number of bytes to be a multiple of 16.

Output should be large enough to hold this. Output can be the same memory block as input

Parameters:
[in] input the input buffer to encrypt
[in] inputLength the size of the input buffer
[in] output the output buffer to store encrypted data
[in] outputLength the size of the output buffer

bool DataBlockEncryptor::IsKeySet ( void   )  const

Returns:
true if SetKey has been called previously

void DataBlockEncryptor::SetKey ( const unsigned char  key[16]  ) 

Set the encryption key.

Parameters:
[in] key The new encryption key
