我在crontab中运行下一个命令加密文件，我不想要键盘交互
echo "PASSPHRASE" | gpg --passphrase-fd 0 -r USER --encrypt FILENAME.TXT
但我有这个答案：
gpg: C042XXXX: There is no assurance this key belongs to the named user
pub 40XXX/C042XXXX 2012-01-11 Name LastName. (comment) <user@email.com>
Primary key fingerprint: XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX
Subkey fingerprint: XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX
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)
正如David所暗示的，这里的问题是gpg不信任你用来加密的公钥。你可以签署密钥，他解释。
另一个选择 – 特别是如果密钥可能偶尔改变 – 将坚持–trust-model总是对你的gpg命令。
