Crypto

I heard about GPG several years ago and finally decided to try it. I ran into some problems, but I figured out a solution that I posted on StackExchange.

What annoyed me though, the output didn’t seem like it would work in a blog. Well, I figured that out too.

Here’s an example test message called test.txt:

start

	start

		testing

		test

	end

end

In Linux, we can encrypt this like…

gpg -ac --pinentry-mode=loopback test.txt

This creates a file called test.txt.asc that looks like this…

Can you post this anywhere? Maybe, maybe not. At least for now, it works with LinkedIn posts. Social networks might change the formatting slightly enough to corrupt your message. But worth trying, just for fun.

Copy-paste this into a file on your PC. Then run gpg --pinentry-mode=loopback test.txt.asc and use the password: asdf

Does it work with WordPress? Yes and no. Apparently, if you use blockquote, WordPress changes the dashes, so use the code tag instead and it works. (Or just remember to use five dashes, etc.) Paste the encrypted text into whatever.gpg (filename doesn’t matter.)

Example:

[]# gpg --pinentry-mode=loopback whatever.blah

gpg: WARNING: no command supplied.  Trying to guess what you mean ...

gpg: AES encrypted data

gpg: encrypted with 1 passphrase

gpg: whatever.blah: unknown suffix

Enter new filename [test.txt]:

[]# cat test.txt

start

	start

		testing

		test

	end

end
