Member Function Documentation

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

Decrypt removes bytes, as few as 6. Output should be large enough to hold this. Output can be the same memory block as input

Parameters:
input the input buffer to decrypt
inputLength the size of the input buffer
output the output buffer to store decrypted data
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
 

Encrypt adds up to 15 bytes. Output should be large enough to hold this. Output can be the same memory block as input

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

bool DataBlockEncryptor::IsKeySet void   )  const
 

Test if encryption/decryption key are set

Returns:
true if SetKey has been called previously

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

Set the encryption key

Parameters:
key The new encryption key

void DataBlockEncryptor::UnsetKey void   ) 
 

Unset the encryption key
