问题描述

我最近一直在GnuPG上工作很多,并且依赖于其加密文件的能力等。

I've been working a great deal with GnuPG lately and have come to depend on its ability to encrypt files, etc.

但是,我目前正在一些涉及通信(即聊天,电子邮件等)的项目,其中我想使用现有密钥来加密/解密文本本身,而不是容器,如文件或磁盘映像。

However, I am currently working on a couple of projects that involve communication (i.e. chat,email, etc) where I'd like to use existing keys to encrypt/decrypt text itself as opposed to a "container" such as a file or disk image.

我想我可以加密容器,将流转换为base64(或适当的东西),然后标记文本,但我猜想有一个更直接的解决方案。我确定有一些简单的东西我失踪了,但是,我错过了。

I suppose I could encrypt the container, convert the stream to base64 (or something appropriate) then mark the text as such, but I would guess there is a more straightforward solution. I'm sure there is something simple I'm missing, but, well, I'm missing it.

任何想法?

推荐答案



What about:

$ echo "hello" | gpg --symmetric --armor --passphrase "asdf"
-----BEGIN PGP MESSAGE-----
Version: GnuPG v1.4.11 (Darwin)

jA0EAwMCWfhRZo0AiwVgyRw5Q26Tf+i6OCiQOVoUNJZEfz5ekBJw6BdVpE88
=ecV3
-----END PGP MESSAGE-----

如果这是你想要的,你需要设置 gpg-agent 来处理密码短语...从命令行传入像这样是相当不安全的(因为机器上的任何程序可能会窃取它)。

If this is what you're looking for, you'll want to setup gpg-agent to handle the passphrase… Passing it in from the command line like that is fairly insecure (as any program on the machine could steal it).

如果通过现有的密钥表示现有的公钥/私钥对然后:

And if by "existing keys" you mean "existing pub/priv key pairs", then:

$ echo "hello" | gpg --encrypt --armor -r B230230D
-----BEGIN PGP MESSAGE-----
Version: GnuPG v1.4.11 (Darwin)

-----END PGP MESSAGE-----

在这两种情况下,消息都使用以下方式解密: p>

In both cases, the message is decrypted using:

$ cat encrypted_message | gpg
gpg: CAST5 encrypted data
Enter passphrase: asdf
gpg: encrypted with 1 passphrase
hello
