PGP Encryption using Console application.

Question

Added the below code. But getting exception as security.Cryptography.CryptographicException: 'Specified initialization vector (IV) does not match the block size for this algorithm.'

 

 Please suggest.

{

{

Program obj = new Program();

obj.DecryptFile("C:\\Pragya\\Bank of Montreal\\LOCKBOX\\LOCKBOXCA201805310001_not processed.zip_522733.exe", "C:\\Pragya\\Bank of Montreal\\LOCKBOX\\pragya.txt");

//Console.WriteLine("Hello World");

//Console.Read();

}

private void EncryptFile(string inputFile, string outputFile)

{

try

{

string password = @"Password@12345"; // Your Key Here

UnicodeEncoding UE = new UnicodeEncoding();

byte[] key = UE.GetBytes(password);

string cryptFile = outputFile;

FileStream fsCrypt = new FileStream(cryptFile, FileMode.Create);

RijndaelManaged RMCrypto = new RijndaelManaged();

CryptoStream cs = new CryptoStream(fsCrypt, RMCrypto.CreateEncryptor(key, key), CryptoStreamMode.Write);

FileStream fsIn = new FileStream(inputFile, FileMode.Open);

int data;

while ((data = fsIn.ReadByte()) != -1)

cs.WriteByte((byte)data);

fsIn.Close();

cs.Close();

fsCrypt.Close();

}

{

Console.Write("In Catch");

Console.Read();
