  Dear Experts Thanx for reply.I gor idea from that links.One more doubt when i decrypt the ecncrypt string using auto generate key its showing error as System.Security.Cryptography.CryptographicException: Bad Data. I give the my function private void DecryptFunctionINGData() { try { string strEncrypt = "9FEDAB741C3B085859D22FB1DDE46F32" ; // Encrypt string TripleDESCryptoServiceProvider tdes = new TripleDESCryptoServiceProvider (); tdes.Key = Encoding .UTF8.GetBytes( "NlQr7tt/AJE/i

  Dear Experts, I had one function in converted from java for generate the auto secret key purpose for encrypt and decrypt the using using AES algorithm..when i used this function in .net its showing SecretKeySpec and KeyGenerator is not defined.Even i used System.Security.Cryptography header name space also. I give the my codes.If any body know help me Private Function keygeneration() As SecretKeySpec Dim skeySpec As SecretKeySpec = Nothing Try Dim kgen As KeyGenerator = KeyGenerator.getInstance("AES"
