간단하게 웹 페이지 하나 만들 일이 생겼는데,
자바 스크립트 좀 훔쳐 볼랬더니 js 파일이 암호화 되어 있다.
하나 하나 만들기 무진장 빡세다 ;;
혹시나 해서 찾아 보니 이런게 있군하~ ㅋㅋ

private static Byte[] ConvertStringToByteArray(String s)
{
return (new UnicodeEncoding()).GetBytes(s);
}
## 암호화
private void encodingFunction()
{
FileStream fs = new FileStream("filename.cfg", FileMode.Create, FileAccess.Write);
String strinput = "암호화할 문자열";
Byte[] bytearrayinput = ConvertStringToByteArray(strinput);
//DES instance with random key
DESCryptoServiceProvider des = new DESCryptoServiceProvider();
//create DES Encryptor from this instance
ICryptoTransform desencrypt = des.CreateEncryptor(ConvertStringToByteArray("1111"), ConvertStringToByteArray("2222"));
//Create Crypto Stream that transforms file stream using des encryption
CryptoStream cryptostream = new CryptoStream(fs, desencrypt, CryptoStreamMode.Write);
//write out DES encrypted file
cryptostream.Write(bytearrayinput, 0, bytearrayinput.Length);
cryptostream.Close();
fs.Close();
}
## 복호화
private void decodingFunction()
{
DESCryptoServiceProvider des = new DESCryptoServiceProvider();
//create file stream to read encrypted file back
FileStream fsread = new FileStream("filename.cfg", FileMode.Open, FileAccess.Read);
//create DES Decryptor from our des instance
ICryptoTransform desdecrypt = des.CreateDecryptor(ConvertStringToByteArray("1111"), ConvertStringToByteArray("2222"));
//create crypto stream set to read and do a des decryption transform on incoming bytes
CryptoStream cryptostreamDecr = new CryptoStream(fsread, desdecrypt, CryptoStreamMode.Read);
//print out the contents of the decrypted file
StreamReader sr = new StreamReader(cryptostreamDecr, new UnicodeEncoding());
while (!sr.EndOfStream)
{
cmbPrefix.Items.Add(sr.ReadLine());
}
fsread.Close();
}
