Python，将 RSA-256 公钥加载到代码中

如何解决Python，将 RSA-256 公钥加载到代码中

我正在尝试在 Python 中加载 RSA-256 中的公钥。

encoded = <my jwt token>
import jwt
decoded = jwt.decode(encoded,public_key,algorithms=["RS256"])

这引发了以下错误：

ValueError: Could not deserialize key data.

所以我尝试以不同的方式加载公钥：

from Crypto.PublicKey import RSA
pub_key = RSA.importKey(public_key)

其中提出：

ValueError: RSA key format is not supported

此外，当我尝试将其加载到二进制文件 (b'----- ...) 时，也会引发相同的错误

更新：

设法使用 pycryptodome 创建 RSA 对象：

from Crypto.PublicKey.RSA import import_key
key = import_key(public_key)

但是在运行时：

decoded = jwt.decode(encoded,key,algorithms=["RS256"])

我得到：

TypeError: Expecting a PEM-formatted key.
