读取PEM字符串时出现PyAsn1错误

我正在尝试在Python中读取PEM编码的公钥.我尝试了多个键和多个可能的解决方案.我尝试了base64解码,其他格式,等等…

我真的不知道该怎么办(因为自从昨天以来我已经遇到了这个问题).

我得到的错误：

Traceback (most recent call last):
  File "I:/path/Main.py", line 6, in <module>
    -----END RSA PUBLIC KEY-----""", format='PEM')
  File "C:\Python34\lib\site-packages\rsa-3.1.4-py3.4.egg\rsa\key.py", line 65, in load_pkcs1

我的代码：

pubkey = rsa.PublicKey.load_pkcs1(b"""-----BEGIN RSA PUBLIC KEY-----
MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBANkHLKYS2dByWQ3gKjQDvQbuWb/2Y9z4
eYuLEfgXdiP5qc5cG/5c+c/GgIl6yQY7AYeZVXiBXLaGzxiLZ5Y4fi0CAwEAAQ==
-----END RSA PUBLIC KEY-----""", format='PEM')
crypto = rsa.encrypt("Secret", pubkey)

解决方法:

我不确定我做对了.但是至少跟随加密没有错误.

import rsa
pubkey = rsa.PublicKey.load_pkcs1_openssl_pem(b"""-----BEGIN PUBLIC KEY-----
MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBANkHLKYS2dByWQ3gKjQDvQbuWb/2Y9z4
eYuLEfgXdiP5qc5cG/5c+c/GgIl6yQY7AYeZVXiBXLaGzxiLZ5Y4fi0CAwEAAQ==
-----END PUBLIC KEY-----""")
crypto = rsa.encrypt(b"Secret", pubkey)

注意：我将BEGIN RSA PUBLIC KEY更改为BEGIN PUBLIC KEY. (与END RSA PUBLIC KEY相同).我使用了load_pkcs1_openssl_pem.

更新

传递字节对象而不是str(尤其是如果您在Python 3.x中运行此对象).
