 In asp.net for encryption and decryption follow these  steps: 
 
 
Step1:  Create a class and make 2 function in this class . one for encrypting the string and another for decrypting that string. 
 
Step2: In class firstly include this NameSpace. 
 
 using System.Text; 
 
 
Step3: Now Create a Function for encrypting the string 
 
  public string Encryptdata(string password) 
    { 
        string strmsg = string.Empty; 
        byte[] encode = new 
        byte[password.Length]; 
        encode = Encoding.UTF8.GetBytes(password); 
        strmsg = Convert.ToBase64String(encode); 
        return strmsg; 
    } 
 
Step4: Now Create a Function for decrypting the string  
 
    public string Decryptdata(string encryptpwd) 
    { 
        string decryptpwd = string.Empty; 
 
        UTF8Encoding encodepwd = new UTF8Encoding(); 
        System.Text.Decoder utf8Decode = encodepwd.GetDecoder(); 
        byte[] todecode_byte = Convert.FromBase64String(encryptpwd); 
        int charCount = utf8Decode.GetCharCount(todecode_byte, 0, todecode_byte.Length); 
        char[] decoded_char = new char[charCount]; 
        utf8Decode.GetChars(todecode_byte, 0, todecode_byte.Length, decoded_char, 0); 
        decryptpwd = new String(decoded_char); 
        return decryptpwd; 
 
    } 
 
 
Step5: Now on your aspx.cs page: 
 
Now for encrpting a string: 
 
 
 
string str="Pradeep Lodhi"; 
 
 
string encrptedstr=Encryptdata(str); 
 
 
 
for decrypting : 
 
 
string decryptstr=Decryptdata(str);</div>
</div>
</div>
