Syntax

C#
public String Decrypt(Byte[] cipher, Byte[] key, Byte[] initializationVector)

Returns a decrypted string from a cipher byte array. (E)

Example

C#
MemoryCrypto crypto = new MemoryCrypto(); string text = null; byte[] key = {230, 191, 149, 1, 207, 136, 112, 200 , 7, 192, 109, 130, 188, 192, 27, 183 , 238, 1, 248, 74, 35, 47, 1, 144 , 90, 91, 5, 167, 87, 170, 11, 141}; byte[] iv = {94, 9, 42, 5, 218, 86, 120, 94 , 209, 208, 216, 111, 24, 4, 255, 67}; byte[] cipher; // Retrieve value. text = GetEncryptedValue(); // Convert from Base64 and decrypt to text. cipher = Convert.FromBase64String(text); crypto.CryptoType = Crypto_Type.Crypto_Rijndael; text = crypto.Decrypt(cipher, key, iv);
