我想將以下python代碼遷移到c#中。 入口點是方法encrypted_request從Python到C#的AES/RSA實現#
我沒有真正的線索關於python或在c#中的aes/rsa。 也許有人可以解釋不同的代碼段,如果可能的話給我一個提示如何在c#中實現。 特別是在這裏和那裏使用的神奇數字我不明白。
modulus = ('00e0b509f6259df8642dbc35662901477df22677ec152b5ff68ace615bb7'

'3ece0462db0a22b8e7')
nonce = '0CoJUm6Qyw8W8jud'
pubKey = '010001'
def encrypted_request(text):
text = json.dumps(text)
secKey = createSecretKey(16)
encText = aesEncrypt(aesEncrypt(text, nonce), secKey)
encSecKey = rsaEncrypt(secKey, pubKey, modulus)
data = {'params': encText, 'encSecKey': encSecKey}
return data
def aesEncrypt(text, secKey):
pad = 16 - len(text) % 16
text = text + chr(pad) * pad
encryptor = AES.new(secKey, 2, '0102030405060708')
ciphertext = encryptor.encrypt(text)
ciphertext = base64.b64encode(ciphertext).decode('u8')
return ciphertext
def rsaEncrypt(text, pubKey, modulus):
text = text[::-1]
rs = pow(int(binascii.hexlify(text), 16), int(pubKey, 16)) % int(modulus, 16)
return format(rs, 'x').zfill(256)
def createSecretKey(size):
return binascii.hexlify(os.urandom(size))[:16]

我目前在C#中的狀態:
private byte[] hex2Binary(string hex) {
byte[] binaryVal = new byte[hex.Length];
for (int i = 0; i < hex.Length; i++) {
string byteString = hex.Substring(i, 1);
byte b = Convert.ToByte(byteString, 16);
binaryVal[i] = b;
}
return binaryVal;
}
private string aesEncryptBase64(String plainText, string key) {
return aesEncryptBase64(plainText, hex2Binary(key));
}
private string aesEncryptBase64(String plainText, byte[] key) {
//pad = 16 - len(text) % 16
//text = text + chr(pad) * pad
int pad = 16 - plainText.Length % 16;
for (int i=0; i<pad; i++) {
plainText = plainText + ((char)pad);
}
byte[] plainBytes = null;
RijndaelManaged aes = new RijndaelManaged();
//aes.KeySize = 16;
aes.Mode = CipherMode.CBC;
aes.Key = key;
aes.IV = hex2Binary(client.neteaseFix.encryptInfo.iv);
MemoryStream ms = new MemoryStream();
CryptoStream cs = new CryptoStream(ms, aes.CreateEncryptor(), CryptoStreamMode.Write);
cs.Write(plainBytes, 0, plainBytes.Length);
cs.Close();
byte[] encryptedBytes = ms.ToArray();
return Convert.ToBase64String(encryptedBytes); //decode("u8")
}
您是否理解算法的工作原理(例如,對稱密鑰和公鑰加密之間的區別,RSA如何加密/解密數據,何時使用RSA和AES等)? – EJoshuaS
我知道AES是對稱和快速的,RSA是公開密鑰,並且質數慢。所以我會使用rsa來加密我的aes密鑰,以便將密鑰的速度和安全傳輸與rsa結合起來。 – Schnulli
