See the following links:
 
Simple String Encryption and Decryption with Source Code[^]
Encrypt and Decrypt a String[^]
 
For Decrypt
byte[] encData_byte = new byte[string.Length];
 
encData_byte = System.Text.Encoding.UTF8.GetBytes(Textbox3.Text);
 
string encodedData = Convert.ToBase64String(encData_byte);
 
result= encodedData;
 
for Encrypt:
System.Text.UTF8Encoding encoder = new System.Text.UTF8Encoding();
 
System.Text.Decoder utf8Decode = encoder.GetDecoder();
 
byte[] todecode_byte = Convert.FromBase64String(string);
 
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);
 
string result = new String(decoded_char);
