Hi Rub?n, thanks for mentioning this. I must have accidentally dropped the corresponding paragraph in the docs (http://alot.readthedocs.org/en/testing/usage/index.html#cryptography). I'm almost certain I saw this documented a while back..
Basically, you need a running gpg-agent. Then, decryption of mails should happen automatically once you open a thread. The same holds for signature verification (the status of which will be mentioned in a pseudo-header). This holds for mails that comply PGP/MIME only. "ASCII-armored" text in plaintext parts is not dealt with. If this does not work, you've found a bug that you should kindly report :) HTH, /p
