Hi  Try below Code. /// /// Encrypts a given password and returns the encrypted data /// as a base64 string. /// /// An unencrypted string that needs /// to be secured. /// A base64 encoded string that represents the encrypted /// binary data. /// /// This solution is not really secure as we are /// keeping strings in memory. If runtime protection is essential /// should be used. /// If /// is a null reference. public string Encrypt(string plainText) { if (plainText == null) throw new ArgumentNullException(plainText); //encrypt data var data = Encoding.Unicode.GetBytes(plainText); byte[] encrypted = ProtectedData.Protect(data null Scope); //return as base64 string return Convert.ToBase64String(encrypted); } /// /// Decrypts a given string. /// /// A base64 encoded string that was created /// through the or /// extension methods. /// The decrypted string. /// Keep in mind that the decrypted string remains in memory /// and makes your application vulnerable per se. If runtime protection /// is essential should be used. /// If /// is a null reference. public string Decrypt(string cipher) { if (cipher == null) throw new ArgumentNullException(cipher); //parse base64 string byte[] data = Convert.FromBase64String(cipher); //decrypt data byte[] decrypted = ProtectedData.Unprotect(data null Scope); return Encoding.Unicode.GetString(decrypted); } Reference: http://stackoverflow.com/questions/1678555/password-encryption-decryption-code-in-net Regards Kunal.
