decrypt multiple OpenPGP files in a directory
提问by user1815498
I have several hundred gpg encrypted files in a directory, of the format filename.xyz.gpg where "xyz" is some arbitrary extension. I need to decrypt all of the files to generate filename.xyz decrypted in such a way that I don't have to manually enter the password for each file.
我在一个目录中有数百个 gpg 加密文件，格式为 filename.xyz.gpg，其中“xyz”是一些任意扩展名。我需要解密所有文件以生成解密的 filename.xyz，这样我就不必为每个文件手动输入密码。
I have tried the following for directory "Testing":
我已经尝试了以下目录“测试”：
for file in 'ls Testing'; do (echo <password>|gpg --passphrase-fd 0 -d $file
--output $file.decrypted);
I just wind up with a command prompt >, and nothing happens.
我只是以命令提示符 > 结束，然后什么也没有发生。
What is the matter with my syntax? Is there some more efficient way to do this without a bash shell loop?
我的语法有什么问题？在没有 bash shell 循环的情况下，有没有更有效的方法来做到这一点？

As it is said in the manual you need to add --batchoption:
正如手册中所说，您需要添加--batch选项：
--passphrase-fd n
Read the passphrase from file descriptor n. Only the first line will be read from file descriptor n. If you use 0 for n, the passphrase will be read from
STDIN. This can only be used if only one passphrase is supplied. Note that this passphrase is only used if the option --batch has also been given. This is
different from gpg.
--passphrase string
Use string as the passphrase. This can only be used if only one passphrase is supplied. Obviously, this is of very questionable security on a multi-user sys‐
tem. Don't use this option if you can avoid it. Note that this passphrase is only used if the option --batch has also been given. This is different from
gpg.
You can have either of these two forms:
您可以使用以下两种形式之一：
echo "passphrase" | gpg --passphrase-fd 0 --batch -d --output "decrypted.file" "file.gpg"
Or simpler:
或者更简单：
gpg --passphrase "passphrase" --batch -d --output "decrypted.file" "file.gpg"
You can try a script like this to extract your files:
您可以尝试使用这样的脚本来提取文件：
#!/bin/bash
read -rsp "Enter passphrase: " PASSPHRASE
for FILE in *.*.gpg; do
echo "Extracting $FILE to ${FILE%.gpg}."
echo "$PASSPHRASE" | gpg --passphrase-fd 0 --batch -d --output "${FILE%.gpg}" "$FILE"
done

gpgcan decrypt multiple files so you shouldn't need to write a loop.
gpg可以解密多个文件，因此您不需要编写循环。
Try the following. You will need to enter your password once.
请尝试以下操作。您需要输入一次密码。
gpg --passphrase-fd 0 --decrypt-files *.gpg

I had success with gpg --decrypt-files * but not *.gpg
我在 gpg --decrypt-files * 上取得了成功，但 *.gpg 没有成功

It worked with below commands for me:
它适用于我的以下命令：
For single file:
gpg --decrypt --input C:\PGPFiles\[encryptedfilename.pgp] --passphrase [yourpassphrase]
对于单个文件：
gpg --decrypt --input C:\PGPFiles\[encryptedfilename.pgp] --passphrase [yourpassphrase]
For multiple files:
gpg --decrypt --input C:\PGPFiles\* --passphrase [yourpassphrase]
对于多个文件：
gpg --decrypt --input C:\PGPFiles\* --passphrase [yourpassphrase]
