读取PEM字符串时出现PyAsn1错误

Question

我试着用Python读取PEM编码的公钥。我尝试过多个密钥和多种可能的解决方案。我试过base64解码它，其他格式，等等.

我真的不知道该怎么办了(因为我从昨天起就有这个问题了)。

我所犯的错误：

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)

我不确定我做得对。但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:我用BEGIN PUBLIC KEY更改了BEGIN PUBLIC KEY。(END RSA PUBLIC KEY也一样)。我用了load_pkcs1_openssl_pem。

更新

传递一个bytes对象而不是str (特别是在Python3.x中运行这个对象时)。
