Question

java代码：

public String encrypt (String str,String key) throws EncryptException {

    try{
        javax.crypto.spec.SecretKeySpec keyspec = new javax.crypto.spec.SecretKeySpec(key.getBytes(), "AES");
        javax.crypto.Cipher c = javax.crypto.Cipher.getInstance("AES");
        c.init(javax.crypto.Cipher.ENCRYPT_MODE, keyspec);
        byte[] src = str.getBytes("UTF-8");
        byte[] encrypt = c.doFinal(src);
        return new sun.misc.BASE64Encoder().encode(encrypt).replaceAll("\r|\n", "");
    }catch(Exception e){
        throw new EncryptException("Encrypt failed.",e);
    }
}

python代码：

def get_enctypted(self, param_req):
    BS = AES.block_size
    pad = lambda s: s + (BS - len(s) % BS) * chr(BS - len(s) % BS)
    param_json = json.dumps(param_req)
    IV = Random.new().read(AES.block_size)
    cipher = AES.new(self.get_key(), AES.MODE_ECB, IV)
    encrypted = cipher.encrypt(pad(param_json))
    encrypted_base64 = base64.b64encode(IV + encrypted)
    return encrypted_base64

当我使用相同的键和字符串运行代码时，我得到两个不同的结果，有人知道为什么吗？

看看这一行 - IV = Random.new().read(AES.block_size)。您使用random值，因此结果当然不能相同。

python和java用AES加密，但结果不一样
