Remarks

Because the IV (Initialization Vector) has the same distribution as the resulting ciphertext, the IV is randomly generated and prepended to the ciphertext.

Constructors

SymmetricCryptographer(SymmetricAlgorithm, byte[])

Initalize a new instance of the SymmetricCryptographer class with an algorithm type and a key.

public SymmetricCryptographer(SymmetricAlgorithm algorithm, byte[] key)

Parameters

algorithm SymmetricAlgorithm

The qualified assembly name of a SymmetricAlgorithm.

key byte[]

The key for the algorithm.

Methods

Decrypt(byte[])

Decrypts bytes with the initialized algorithm and key.

public byte[] Decrypt(byte[] encryptedText)

Parameters

encryptedText byte[]

The text which you wish to decrypt.

Returns

byte[]

The resulting plaintext.

DisposeManaged()

Disposes the managed resources. Override this method to add custom clean up of managed resources.

protected override void DisposeManaged()

Encrypt(byte[])

Encrypts bytes with the initialized algorithm and key.

public byte[] Encrypt(byte[] plaintext)

Parameters

plaintext byte[]

The plaintext in which you wish to encrypt.

Returns

byte[]

The resulting ciphertext.

ZeroOutBytes(byte[])

Fills bytes zeros.

public static void ZeroOutBytes(byte[] bytes)

Parameters

bytes byte[]

The byte array to fill.
