不支持使用python中提供RSA密钥格式的pem文件加密json

我正在开发一个加密模块，其中请求采用加密JSON格式的参数。此加密由服务器提供的公钥完成，如下所示：

def encrypt_bank_request(request_payload):
    key = ""
    url = "http://localhost/payment/gateways/mybank.pem"
    file = urllib.request.urlopen(url)
    decoded_file = file.read().decode("utf-8")
    for line in decoded_file:
        key += line

    keyDER = base64.b64decode(key)
    keyPub = RSA.importKey(keyDER)
    cipher = Cipher_PKCS1_v1_5.new(keyPub)
    cipher_text = cipher.encrypt(request_payload.encode())
    emsg = base64.b64encode(cipher_text)
    print(emsg);

$pemKey = file_get_contents("http://localhost/payment/gateways/mybank.pem");
openssl_public_encrypt($request_payload, $encrypted, $pemKey);

但是当我执行代码时，我会在

keyPub=RSA.importKey（keyDER）

上看到以下内容：

值错误在/

不支持RSA密钥格式

我试图实现的PHP等价物如下所示：

def encrypt_bank_request(request_payload):
    key = ""
    url = "http://localhost/payment/gateways/mybank.pem"
    file = urllib.request.urlopen(url)
    decoded_file = file.read().decode("utf-8")
    for line in decoded_file:
        key += line

    keyDER = base64.b64decode(key)
    keyPub = RSA.importKey(keyDER)
    cipher = Cipher_PKCS1_v1_5.new(keyPub)
    cipher_text = cipher.encrypt(request_payload.encode())
    emsg = base64.b64encode(cipher_text)
    print(emsg);

$pemKey = file_get_contents("http://localhost/payment/gateways/mybank.pem");
openssl_public_encrypt($request_payload, $encrypted, $pemKey);

openssl\u public\u encrypt

按照建议使用公钥加密数据，并将结果存储到

$encrypted

中

我做错了什么？是否因为函数需要RSA key对象，而我提供的是字符串，在这种情况下，如何将字符串转换为RSA key对象

我指的是,，

谢谢你的建议

另外，我的钥匙如下：

您需要使用，而不是PyCrypto，并且密钥必须是base-64并带有适当的

行，或者您必须自己对base64编码的blob进行base64解码并将结果字节提供给

键字符串。您显示的缺少

行，我希望类似这样：

----BEGIN RSA PRIVATE KEY------

然后是字符串，然后是

，而且您的密钥字符串似乎已损坏。当我手动添加

行时，我尝试使用

openssl

命令

openssl rsa-in keyfile.key-noout-text

解析字符串，然后我得到一个输出，比如

，当我在线检查时，它会给出关于密钥的正确信息。您拥有的不是公钥，这是一个X.509证书。在该证书中，只有一个字段中有公钥。您需要将

行放回原处，或者base64解码您拥有的内容并提供给导入密钥。我猜你用的是pycryptodome软件包，对吧？
