你好，我使用 gpg 来解密 Linux 中的文件，我使用 gpg

shell_exec("gpg --batch --passphrase-file $passphrase_file -d $encrypted_file");

来解密该文件，但我收到以下错误。

gpg: gpg-agent is not available in this session
gpg: can't query passphrase in batch mode
gpg: Invalid passphrase; please try again ...
gpg: can't query passphrase in batch mode
gpg: Invalid passphrase; please try again ...
gpg: can't query passphrase in batch mode

此错误使得逗号看起来不喜欢使用 shell_exec 运行（类似于 sudo/ssh 在使用 shell_exec 运行时警告需要 tyy）::

gpg: gpg-agent is not available in this session

如果直接从 shell 提示符运行它会发生什么？

另外，请确保您不在安全模式下：

shell_exec()（反引号的功能等效）
当 PHP 在安全模式下运行时，此功能被禁用。

使用 phpinfo()

检查该功能是否未禁用：

$ grep 'disable_functions' /etc/php.ini

< strong>编辑：

另外，尝试使用 putenv 将 GNUPGHOME 指向您的 .gnupg 文件夹。

可能是 php 脚本以 httpd 用户身份运行，而 gpg 需要您的站点的“user”用户。

This error makes it appear that the commaand doesnt like to be run using shell_exec (similar to how sudo/ssh warns about needing a tyy when run with shell_exec)::

gpg: gpg-agent is not available in this session

What happens if u run it directly from the shell prompt?

Also, make sure your not in safe mode:

shell_exec() (functional equivalent of backticks)
This function is disabled when PHP is running in safe mode.

Check with phpinfo()

check that the function is not disabled:

$ grep 'disable_functions' /etc/php.ini

Edit:

Also, try using putenv to point GNUPGHOME to your .gnupg folder.

It could be that the php script is being run as the httpd user and the gpg is expecting the 'user' user for your site.

我遇到了从 cron 调用 gpg 的类似问题。
从命令行或 shell 脚本运行时，该命令工作正常。从 cron 运行命令失败，并出现与您遇到的相同错误。
我发现两个资源是很好的 gpg cheetsheet
以及这个答案serverfault

在生成 gpg 密钥后我能够让它工作。

gpg --gen-key

然后用以下方法加密：

gpg -e -r [email protected] backup_file.tgz

I ran into a similar problem calling gpg from cron.
The command works fine when run from the command line or from a shell script. Running the command from cron fails with the same errors you're getting.
Two resources I found were a good gpg cheetsheet
And this answer on serverfault

I was able to get it to work after generating a gpg key.

gpg --gen-key

And then encrypt with:

gpg -e -r [email protected] backup_file.tgz

为了使用相关密码文件解密 gpg 加密文件并通过应用上下文运行它，请使用以下公式：

gpg --no-tty --no-use-agent --yes --passphrase-file <pass-phrase-file>
    --output <decrypted-file-path> --decrypt <encrypted-file-path>

示例：

$ cd /home/app/gpg_example

$ ls -la
-rwxr-xr-x 3 user root 1000 Jan  1 00:00 secret_passphrase.txt
-rwxr-xr-x 3 user root 7000 Jan  1 00:00 encrypted-file.tar.gpg

$ gpg --no-tty --no-use-agent --yes --passphrase-file secret_passphrase.txt
--output decrypted-file.tar --decrypt encrypted-file.tar.gpg

$ ls -la
-rwxr-xr-x 3 user root 1000 Jan  1 00:00 secret_passphrase.txt
-rwxr-xr-x 3 user root 7000 Jan  1 00:00 encrypted-file.tar.gpg
-rwxr-xr-x 3 user root 6970 Jan  1 00:00 decrypted-file.tar # <= that's decrypted file.

In order to decrypt gpg encrypted files using relevant passphrase file and running it through an applicative context, use the following formula:

gpg --no-tty --no-use-agent --yes --passphrase-file <pass-phrase-file>
    --output <decrypted-file-path> --decrypt <encrypted-file-path>

example:

$ cd /home/app/gpg_example

$ ls -la
-rwxr-xr-x 3 user root 1000 Jan  1 00:00 secret_passphrase.txt
-rwxr-xr-x 3 user root 7000 Jan  1 00:00 encrypted-file.tar.gpg

$ gpg --no-tty --no-use-agent --yes --passphrase-file secret_passphrase.txt
--output decrypted-file.tar --decrypt encrypted-file.tar.gpg

$ ls -la
-rwxr-xr-x 3 user root 1000 Jan  1 00:00 secret_passphrase.txt
-rwxr-xr-x 3 user root 7000 Jan  1 00:00 encrypted-file.tar.gpg
-rwxr-xr-x 3 user root 6970 Jan  1 00:00 decrypted-file.tar # <= that's decrypted file.
