读取PEM字符串时发生PyAsn1错误

Question

我试图在Python中读取PEM编码的公钥。我试过多个键和多种可能的解决方案。我尝试过base64解码，其他格式，等等。。。在

我真的不知道该怎么办了（因为从昨天开始我就有这个问题了）。在

我得到了一个错误：

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

Answer 1

我不确定我做得对。但至少在加密之后没有错误。在

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：我用BEGIN PUBLIC KEY更改了BEGIN RSA PUBLIC KEY。（与END RSA PUBLIC KEY相同）。我用了load_pkcs1_openssl_pem。在

更新

传递一个bytes对象，而不是str（尤其是在python3.x中运行此对象时）。在
