gpg 加密和解密
我正在尝试加密和解密字符串。 现在我已经做到了：
mis@fasan:~$ echo "hallo" | gpg --symmetric --pgp8 --cipher-algo AES256 > /tmp/1
Enter passphrase:
Repeat passphrase:
mis@fasan:~$
mis@fasan:~$ cat /tmp/1 | gpg --decrypt
gpg: AES256 encrypted data
Enter passphrase:
gpg: encrypted with 1 passphrase
hallo
mis@fasan:~$
它就像我想要的那样工作。现在我已经用文件中的密码进行了尝试，但它不起作用：
mis@fasan:~$ echo "hallo" | gpg --symmetric --pgp8 --cipher-algo AES256 --passphrase-fd 0 < /home/mis/testgpg > /tmp/1
Reading passphrase from file descriptor 0
mis@fasan:~$
mis@fasan:~$ cat /tmp/1 | gpg --decrypt
gpg: AES256 encrypted data
gpg: encrypted with 1 passphrase
非常有趣的是，他要求提供密码。如果我写错了，我会收到一条错误消息，但如果我写了正确的密码，我不会得到我的密码字符串。 我的目标是达到这个：
mis@fasan:~$ echo "hallo" | gpg --symmetric --pgp8 --cipher-algo AES256 --passphrase-fd 0 < /home/mis/testgpg > /tmp/1
Reading passphrase from file descriptor 0
mis@fasan:~$
mis@fasan:~$ cat /tmp/1 | gpg --decrypt --passphrase-fd 0 < /home/mis/testgpg
Reading passphrase from file descriptor 0
gpg: decrypt_message failed: eof
mis@fasan:~$
但这也行不通。有谁知道我做错了什么？
I am trying to crypt and decrypt Strings.
Now I have done this:
mis@fasan:~$ echo "hallo" | gpg --symmetric --pgp8 --cipher-algo AES256 > /tmp/1
Enter passphrase:
Repeat passphrase:
mis@fasan:~$
mis@fasan:~$ cat /tmp/1 | gpg --decrypt
gpg: AES256 encrypted data
Enter passphrase:
gpg: encrypted with 1 passphrase
hallo
mis@fasan:~$
It works just like I want it to work. Now I have tried it with a passphrase out of a file, but it didn't work:
mis@fasan:~$ echo "hallo" | gpg --symmetric --pgp8 --cipher-algo AES256 --passphrase-fd 0 < /home/mis/testgpg > /tmp/1
Reading passphrase from file descriptor 0
mis@fasan:~$
mis@fasan:~$ cat /tmp/1 | gpg --decrypt
gpg: AES256 encrypted data
gpg: encrypted with 1 passphrase
It is very interesting, that he asks for the passphrase. If I write a wrong one, I get an error message, but if I write the right passphrase, I do not get my cryptet String.
My target is to reach this:
mis@fasan:~$ echo "hallo" | gpg --symmetric --pgp8 --cipher-algo AES256 --passphrase-fd 0 < /home/mis/testgpg > /tmp/1
Reading passphrase from file descriptor 0
mis@fasan:~$
mis@fasan:~$ cat /tmp/1 | gpg --decrypt --passphrase-fd 0 < /home/mis/testgpg
Reading passphrase from file descriptor 0
gpg: decrypt_message failed: eof
mis@fasan:~$
But this doesn't work either. Does anyone know, what I am doing wrong?

您尝试通过同一文件描述符推送要加密的测试 (
echo "hallo" |) 和密码短语 () （0，这是标准输入）。这些重定向中只有一种可以成功，那就是密码短语。对这两个任务使用不同的文件或文件描述符。例如，使用文件描述符 #3 作为密码：
You are trying to push both the test to encrypt (
echo "hallo" |) and the pass phrase (< /home/mis/testgpg) through the same file descriptor (0, which is stdin). Only one of those redirection can succeed and it is the pass phrase. Use a different file or file descriptor for the two tasks.E.g., using file descriptor #3 for the pass phrase:
