我试图将公钥发送到使用python构建的服务器,并且在调用load_pem_public_key时遇到以下错误
key = serialization.load_pem_public_key(pem_data,后端= default_backend()) 文件 " /usr/local/lib/python3.5/dist-packages/cryptography/hazmat/primitives/serialization.py" ;, 第24行,在load_pem_public_key中 return backend.load_pem_public_key(data)File" /usr/local/lib/python3.5/dist-packages/cryptography/hazmat/backends/openssl/backend.py", 第1040行,在load_pem_public_key中 self._handle_key_loading_error()File" /usr/local/lib/python3.5/dist-packages/cryptography/hazmat/backends/openssl/backend.py", 第1291行,在_handle_key_loading_error中 提出ValueError("无法反序列化关键数据。")ValueError:无法反序列化关键数据。
我的功能就像:
pem_data = request.args.get('public_key').encode()
key = serialization.load_pem_public_key(pem_data,backend=default_backend())
pem_data看起来像(PEM格式)

感谢您的帮助!
答案 0 :(得分:0)
这似乎无效。我无法使用openssl
加载它。
它包含空格。
详细信息:
$ cat pubkey.pem
