Public Member Functions
bool	ComputeHash (byte *buffer, ref int bufferLength, int capacity)
	Compute the Buffer hash and append it to the buffer itself. Parameters buffer Data to compute the hash bufferLength Length of the data to hash capacity Buffer total capacity Returns True if the hash was properly computed, false otherwise
bool	DecryptData (byte *buffer, ref int bufferLength, int capacity)
	Decrypt data in place and update it's length. Parameters buffer Data to decrypt bufferLength Length of the data to decrypt capacity Buffer total capacity Returns True if the decryption was completed, false otherwise
void	Dispose ()
	Dispose of the DataEncryptor.
bool	EncryptData (byte *buffer, ref int bufferLength, int capacity)
	Encrypts the data in the provided buffer.
byte[]	GenerateKey ()
	Generate the key used used by the encryption implementation. Returns Key used to setup the encryption implementation
void	Setup (byte[] key)
	Setup the encryption implementation with the right key.
bool	ValidateKey (byte[] key)
	Check if the given key is valid. Returns True if fulfills all requirements for a valida key
bool	VerifyHash (byte *buffer, ref int bufferLength, int capacity)
	Verify the buffer hash that was appended to the buffer. Parameters buffer Buffer to check the hash bufferLength Length of the data to hash capacity Buffer total capacity Returns True if the hash was properly verified, false otherwise

Detailed Description

Responsible for encrypting and decrypting data buffers.

Member Function Documentation

EncryptData()

bool EncryptData	(	byte *	buffer,
		ref int	bufferLength,
		int	capacity )

Encrypts the data in the provided buffer.

Parameters

buffer	The buffer containing the data to be encrypted.
bufferLength	The length of the data in the buffer.
capacity	The total capacity of the buffer.

Returns

Returns true if the encryption was successful, false otherwise.

Exceptions

InvalidOperationException	Thrown when the encryption provider is not initialized.
ArgumentException	Thrown when the original buffer cannot hold the encrypted data.
