Question

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＆＃34; /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＆＃34; /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＆＃34; /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（＆＃34;无法反序列化关键数据。＆＃34;）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！

Answer 1

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
