Encryption / Decryption in C#

Introduction:

As as web Developer some times you need encryption and Decryption in c#. for this purpose a quick code snap is given below.

Solution:

C# Encryption Function:

public static string Encrypt(string textToEncrypt, int key)

    {

        StringBuilder inSb = new StringBuilder(textToEncrypt);

        StringBuilder outSb = new StringBuilder(textToEncrypt.Length);

        char c;

        for (int i = 0; i < textToEncrypt.Length; i++)

        {

            c = inSb[i];

      

            if (c <= 32)

            {

           

            }

            else

            {

                c = (char)((c - key));     

            }

            outSb.Append(c);

        }

        return outSb.ToString();

    }

C# Decryption Function:

public static string Decrypt(string textToEncrypt, int key)

    {

        StringBuilder inSb = new StringBuilder(textToEncrypt);

        StringBuilder outSb = new StringBuilder(textToEncrypt.Length);

        char c;

        for (int i = 0; i < textToEncrypt.Length; i++)

        {

            c = inSb[i];     

            if (c <= 32)

            {

         

            }

            else

            {

                c = (char)((c + key));   

            }

            outSb.Append(c);

        }

        return outSb.ToString();

    }

Key points for use:

• Provide same key in both function for Encryption and Decryption.
