In .net you can easily encrypt/decrypt string.
The following code describes how to do:
/// <summary>
/// To encrypt the input password
/// </summary>
/// <param
name="txtPassword"></param>
/// <returns>It returns encrypted code</returns>
public string EncryptPassword(string
txtString)
{
byte[]
passBytes = System.Text.Encoding.Unicode.GetBytes(txtString);
string
encryptPassword = Convert.ToBase64String(passBytes);
return
encryptPassword;
}
/// <summary>
/// To Decrypt password
/// </summary>
/// <param name="encryptedPassword"></param>
/// <returns>It returns plain password</returns>
public string DecryptPassword(string
encryptedString)
{
byte[]
passByteData = Convert.FromBase64String(encryptedString);
string
originalPassword = System.Text.Encoding.Unicode.GetString(passByteData);
return
originalPassword;
}
You can do it in another way:
/// <summary>
///
/// </summary>
/// <param
name="password"></param>
/// <returns>It returns encyped string</returns>
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;
}
/// <summary>
///
/// </summary>
/// <param
name="encryptpwd"></param>
/// <returns>It returns text string</returns>
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;
}
