CipherStreamBytes Method

public static byte[] Bytes(
	byte[] input,
	byte[] key,
	byte[] iv,
	int counter,
	CipherStreamAlgorithm streamAlg
)

Public Shared Function Bytes ( 
	input As Byte(),
	key As Byte(),
	iv As Byte(),
	counter As Integer,
	streamAlg As CipherStreamAlgorithm
) As Byte()

Parameters

input  Byte

Input data to be encrypted

key  Byte

Key

iv  Byte

Initialization Vector (IV, nonce) or null for Arcfour

counter  Int32

Counter value for ChaCha20 only, otherwise ignored. Use 0 for default.

streamAlg  CipherStreamAlgorithm

Stream cipher algorithm

Return Value

• Arcfour: any length key; specify null for IV.
• Salsa20: key must be exactly 16 or 32 bytes and IV exactly 8 bytes long.
• ChaCha20: key must be exactly 16 or 32 bytes and IV exactly 8, 12, or 16 bytes long. Counter is ignored if IV is 16 bytes.
