sorry my above post formatting looks odd refer this clean code Please click checkbox This is correct answer if you find it helpful! 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); } 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); }

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 ); } 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 ); }
