2020-12-21 Manual autocrypt

I got encrypted mail, yay! I noticed that the sender had helpfully used autocrypt, because there was a header:

Autocrypt: addr=somebody@example.com; keydata=
 ABC...
 DEF...

How to extract this? I don’t know. I know that with Delta Chat, this would have just worked. I noticed that Emacs has a package implementing autocrypt, but I don’t actually want to setup an account and I don’t understand all the extras it does (gossip‽) – so I wanted to do it manually.

=> autocrypt

I saved the keydata in a file and decoded it, ignoring the whitespace at the beginning of each line:

base64 --ignore-garbage --decode test.txt > test.key

And imported it:

gpg --import test.key

Phew! 😅
