[emacs-berlin] Encrypted emails from emacs

[jman]

Hello,

I was looking to refresh my memory about sending PGP encrypted emails from emacs, I use mu4e but I 
think it's not very important since GnuPG integration is provided by emacs itself and every email 
client uses that.

IIUC the easiest and probably suggested way is using a few high-level functions offered by EasyPG to 
encrypt (`M-x epa-mail-decrypt`), decrypt (`M-x epa-mail-decrypt`) and sign (`M-x epa-mail-sign`) a 
message as they all seems to assume the buffer to be an email.
https://www.gnu.org/software/emacs/manual/html_mono/epa.html#Mail_002dmode-integration

However, there are also functions available from the `mml-secure.el` package to do the exact same 
thing:
`M-x mml-secure-message-encrypt-pgp` and `M-x mml-secure-message-sign-pgp`. A decrypt function seems 
to be missing.

So, can I assume that using EasyPG for an email PGP workflow is the suggested option? Why and in 
which cases one would prefer using the mml-* functions?

Mind that I want to update the mu4e documentation, so this decision will have cascading effects! :-)

thanks
