我想使用C#加密字符串并使用Python对其进行解密。加密/解密部分按预期工作(即,我能够解密最初加密的字符串)。然而,Python返回的字符串在开始时有2个额外的字节,每个字符之间用空格分隔。在Python中解密使用.NET加密的字符串
**Original string** (before encryption -- encrypted using C#) = "Something you want to keep private with AES"
**Decrypted string** (using Python) = "��S o m e t h i n g y o u w a n t t o k e e p p r i v a t e w i t h A E S"
为什么我在字符串的开头得到这两个额外的字节?为什么解密字符串中的所有空格?任何想法为什么?
谢谢!
加密用C#
public static string Encrypt<T>(string value, string password, string salt)
where T : SymmetricAlgorithm, new()
{
DeriveBytes rgb = new Rfc2898DeriveBytes(password, Encoding.Unicode.GetBytes(salt));
SymmetricAlgorithm algorithm = new T();
byte[] rgbKey = rgb.GetBytes(algorithm.KeySize >> 3);
byte[] rgbIV = rgb.GetBytes(algorithm.BlockSize >> 3);
ICryptoTransform transform = algorithm.CreateEncryptor(rgbKey, rgbIV);
using (MemoryStream buffer = new MemoryStream())
{
using (CryptoStream stream = new CryptoStream(buffer, transform, CryptoStreamMode.Write))
{
using (StreamWriter writer = new StreamWriter(stream, Encoding.Unicode))
{
writer.Write(value);
}
}
return Convert.ToBase64String(buffer.ToArray());
}
}
string plain = "Something you want to keep private with AES";
string encrypted = CipherUtility.Encrypt<AesManaged>(plain, "password", "salt");
解密与Python + pycrypto
import base64, sys
import Crypto.Cipher.AES
password = base64.b64decode('PSCIQGfoZidjEuWtJAdn1JGYzKDonk9YblI0uv96O8s=') # See rgbKey
salt = base64.b64decode('ehjtnMiGhNhoxRuUzfBOXw==') # See rgbIV
aes = Crypto.Cipher.AES.new(password, Crypto.Cipher.AES.MODE_CBC, salt)
text = base64.b64decode('QpHn/fnraLswwI2Znt1xTaBzRtDqO4V5QI78jLOlVsbvaIs0yXMUlqJhQtK+su2hYn28G2vNyLkj0zLOs+RIjElCSqJv1aK/Yu8uY07oAeStqRt4u/DVUzoWlxdrlF0u')
print aes.decrypt(text)
