It is only after the encrypted data is sent in the querystring that it fails. if (plainText == null || plainText.Length <= 0) throw new ArgumentNullException("plainText"); byte[] encrypted; // Create an RijndaelManaged object // with the specified key and IV. have a peek at this web-site

byte[] keyBytes = password.GetBytes(keySize / 8); // Create uninitialized Rijndael encryption object. Insults are not welcome. If you encoded it with Base64, you must convert it back to binary with Base64.

Not the answer you're looking for? Rolling your own security code is almost always a bad idea.

Allowed values are: "MD5" and /// "SHA1". ICryptoTransform decryptor = rijAlg.CreateDecryptor(rijAlg.Key, rijAlg.IV); byte[] decryptedText = decryptor.TransformFinalBlock(cipherText, 0, cipherText.Length); string decrpyted = ASCIIEncoding.UTF8.GetString(decryptedText); // Create the streams used for decryption. These are my methods: private void transferFile(FileInfo file, long position, long readBytes) { // transfer on socket stream Stream stream = new FileStream(file.FullName, FileMode.Open); if (position > 0) { stream.Seek(position, SeekOrigin.Begin); After Base64 encryption (which results in a 4/3 expansion of the output) 751 bytes of plaintext puts you just under 1024 bytes of encrypted data.
