GNUPG指纹未识别为加密的有效收件人

Question

密钥的GNUPG指纹未被确定为加密的有效收件人。根据此doc https：//pythonhosted.org/python-python-gython-gnupg/ #encryptig 我们可以使用指纹。但是它不起作用。

>>> import gnupg
>>> gpg = gnupg.GPG(gnupghome="/home/user/.gnupg")
>>> key_data = open('/home/user/path/to/public_key.pgp').read()
>>> import_result = gpg.import_keys(key_data)
>>> test_status = gpg.encrypt('test', import_result.fingerprints[0])
>>> test_status.status
'invalid recipient'
>>> 

Answer 1

如果要从命令行尝试相同的过程，则在尝试将消息加密到收件人（gpg -ea -ea -r＆lt＆lt; enterprint＆gt;）时，会看到以下错误

It is NOT certain that the key belongs to the person named
in the user ID.  If you *really* know what you are doing,
you may answer the next question with yes.

Use this key anyway? (y/N)

。在将其用作收件人之前“信任”密钥。您可以使用trust_keys方法来执行此操作：

>>> import_result = gpg.import_keys(key_data)
>>> gpg.trust_keys(import_result.fingerprints[0], 'TRUST_ULTIMATE')
<gnupg.TrustResult object at 0x7f2ab0b22e30>
>>> test_status = gpg.encrypt('test', import_result.fingerprints[0])
>>> test_status.status
'encryption ok'

另外，您可以设置ewnder_trust参数：

>>> import_result = gpg.import_keys(key_data)
>>> test_status = gpg.encrypt('test', import_result.fingerprints[0], always_trust=True)
>>> test_status.status
'encryption ok'

ewndery_trust option 在文档中。
