Member Function Documentation

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

Encryption adds up to 15 bytes. 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
