For Encrypt AND Decrypt Password

NAMESPACE Required:-

using System.Security.Cryptography;

using System.Text;

using System.IO;

FOR Encrypt:-

   private string Encrypt(string clearText)

    {

        string EncryptionKey = "MAKV2SPBNI99212";

        byte[] clearBytes = Encoding.Unicode.GetBytes(clearText);

        using (Aes encryptor = Aes.Create())

        {

            Rfc2898DeriveBytes pdb = new Rfc2898DeriveBytes(EncryptionKey, new byte[] { 0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76 });

            encryptor.Key = pdb.GetBytes(32);

            encryptor.IV = pdb.GetBytes(16);

            using (MemoryStream ms = new MemoryStream())

            {

                using (CryptoStream cs = new CryptoStream(ms, encryptor.CreateEncryptor(), CryptoStreamMode.Write))

                {

                    cs.Write(clearBytes, 0, clearBytes.Length);

                    cs.Close();

                }

                clearText = Convert.ToBase64String(ms.ToArray());

            }

        }

        return clearText;

    }

FOR ​

Decrypt

​:-

​

    private string 

​​

Decrypt(string cipherText)

    {

        string EncryptionKey = "MAKV2SPBNI99212";

        byte[] cipherBytes = Convert.FromBase64String(cipherText);

        using (Aes encryptor = Aes.Create())

        {

            Rfc2898DeriveBytes pdb = new Rfc2898DeriveBytes(EncryptionKey, new byte[] { 0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76 });

            encryptor.Key = pdb.GetBytes(32);

            encryptor.IV = pdb.GetBytes(16);

            using (MemoryStream ms = new MemoryStream())

            {

                using (CryptoStream cs = new CryptoStream(ms, encryptor.CreateDecryptor(), CryptoStreamMode.Write))

                {

                    cs.Write(cipherBytes, 0, cipherBytes.Length);

                    cs.Close();

                }

                cipherText = Encoding.Unicode.GetString(ms.ToArray());

            }
