python - 使用 python gnupg，我的私钥被作为公钥读入

Question

我不确定是什么导致了这个问题。我正在使用 Python 3.6.1::Anaconda 4.4.0(64 位)和 gnupg 版本 2.3.1。

我的代码如下:

import gnupg

gpg = gnupg.GPG(binary='C:/GnuPG/bin/gpg.exe', homedir='./pgp')
pri_key = 'pri_key.pgp'
pub_key = 'pub_key.pgp'

key_data = open(pri_key, 'rb').read()
import_result = gpg.import_keys(key_data)
print(import_result.results)

gpg.list_keys(secret=True) # []
gpg.list_keys() 
'''
[{'algo': '1',
  'date': '1510176716',
  'dummy': '',
  'expires': '',
  'fingerprint': '...',
  'keyid': '...',
  'length': '2048',
  'ownertrust': '-',
  'rev': {},
  'sigs': {'Alex F <alexf@outlook.com>': []},
  'subkeys': [['...', 'e']],
  'trust': '-',
  'type': 'pub',
  'uids': ['Alex F <alexf@outlook.com>']}]
'''

我的私钥如下:

-----BEGIN PGP PRIVATE KEY BLOCK-----
Version: OpenPGP.js v2.0.0
Comment: http://openpgpjs.org

xcLYB...
-----END PGP PRIVATE KEY BLOCK-----

我也能够很好地读取公钥。

我也在这里开了一个案例https://github.com/isislovecruft/python-gnupg/issues/216 .

更新:

感谢 @fuglede 提供 GnuPG 版本 1.4.2 的提示。我可以从这里下载它https://lists.gnupg.org/pipermail/gnupg-announce/2015q4/000382.html 。

下载后我可以成功读取私钥。然而，当我尝试读取我的公钥时，它似乎没有被加载。这是带有附加输出的完整代码。

我认为现在的问题是公钥没有被读入，正如读取时Not 实际上更改\n 所证明的那样。当我尝试加密时，它显示stderr:gpg:--recipient:skipped:未找到公钥。

这只是答案的一半，但显然不适合评论。你所做的在 Python 3.6.3、python-gnupg 2.3.1 和 gpg 1.4.20 中对我来说效果很好，也在 Windows 上:

您能否提供观察到的行为所适用的 key_data 值？

更新答案以回答更新的问题:

用于GPG.encrypt 的语法已关闭。根据the documentation ，数据的加密是通过gpg.encrypt(data,recipients)执行的，其中“recipients是这些接收者的 key 指纹列表。 ”在上面的示例中，这意味着消息可以按如下方式加密:

In [54]: encrypted_data = gpg.encrypt('test', 'D2E8871D9EFFD91B1569FD48105FDBE9E1923472')

In [55]: encrypted_data.ok, str(encrypted_data)
