서버 측에서 이진 파일을 암호화하고 클라이언트 측에서 C#으로 Unity에서 해독하려고합니다.CryptographicException : RijndaelManaged로 이진 파일의 암호를 해독 할 때 입력 블록 크기가 올바르지 않습니다.
코드 서버 측 :
var reader = new FileReader();
if(body.hasClass('encrypt')){
// Encrypt the file!
reader.onload = function(e){
// Use the CryptoJS library and the AES cypher to encrypt the
// contents of the file, held in e.target.result
var key = CryptoJS.enc.Utf8.parse('8080808080808080');
var iv = CryptoJS.enc.Utf8.parse('8080808080808080');
var encrypted = CryptoJS.AES.encrypt(e.target.result, key, {
iv: iv,
mode: CryptoJS.mode.CBC,
padding: CryptoJS.pad.Pkcs7
});
a.attr('href', 'data:application/octet-stream,' + encrypted);
a.attr('download', file.name + '.encrypted');
step(4);
};
// This will encode the contents of the file into a data-uri.
// It will trigger the onload handler above, with the result
reader.readAsDataURL(file);
}
클라이언트의 C#의 코드 :
var keybytes = Encoding.UTF8.GetBytes("8080808080808080");
var iv = Encoding.UTF8.GetBytes("8080808080808080");
FileStream fsCrypt = new FileStream(inputFilePath, FileMode.Open);
RijndaelManaged RMCrypto = new RijndaelManaged();
//setting parameter for decrypting
RMCrypto.Mode = CipherMode.CBC;
RMCrypto.Padding = PaddingMode.PKCS7;
RMCrypto.FeedbackSize = 128;
RMCrypto.Key = keybytes;
RMCrypto.IV = iv;
CryptoStream cs = new CryptoStream(fsCrypt,
RMCrypto.CreateDecryptor(RMCrypto.Key, RMCrypto.IV),
CryptoStreamMode.Read);
FileStream fsOut = new FileStream(outputFilePath, FileMode.Create);
int data;
while ((data = cs.ReadByte()) != -1)
fsOut.WriteByte((byte)data);
fsOut.Close();
cs.Close();
fsCrypt.Close();
내가 성공적으로 암호화 이진 파일을 가지고,하지만 난 클라이언트 측에서 그것을 해독 할 때, 나는 오류가 발생했습니다 :
