我对密码学完全陌生。我想从服务器端生成RSA密钥对并将其发送到所有客户端(浏览器)。但在此之前，我只需在python中加密数据并发送到索引.html文件，并尝试用JavaScript解密。问题是当我通过random_generator = Random.new().read
key = RSA.generate(1024, random_generator)
print key.exportKey() #
public_key = key.publickey()
print public_key.exportKey() #
msg = "hello"
enc_data = public_key.encrypt(msg, 32)
print '----ENCRYPTED DATA----'
enc = enc_data[0]
然后发送加密数据enc，它会给我这个错误：
^{pr2}$
我试着把它变成enc = base64.b64encode(enc_data[0])
而且发送时没有出错。但是JS decrypt方法没有得到任何结果var enc_from_python = $('#input').val();
console.log("ENCRYPTED data:", enc_from_python);
var decrypt = new JSEncrypt();
decrypt.setPrivateKey($('#privkey').val());
var uncrypted = decrypt.decrypt(enc_from_python);
console.log(">>>",uncrypted); //
这两个代码本身都能很好地完成enc/dec。我还尝试用从python接收到的密钥对来enc/dec JS中的数据，效果很好。我想问题是来自Pycrypto的编码数据的unicode编码格式不匹配。有谁能告诉我我在这里遗漏了什么吗。在
