Apologies for the newbie question...
Looking at the main docs, it suggests there is support for OpenPGP but I can't see where. I did come across https://github.com/niklasfemerstrand/rc_openpgpjs but that appears dead.
Has it recently been integrated into RC as I can't see it listed as a plugin nor in the PHP browser...
I'm running RC 1.4.3 so if I need to upgrade, I can look into that.
Thanks.
Roundcube supports OpenPGP when using Mailvelope https://mailvelope.com/en/help
Thanks SKaero.
In fact, I just found out that the enigma plugin supports PGP and after some reading, I have more or less configured it and have it working.
But Mailvelope is an interesting alternative. I guess it just means that configuratio is done on your local browser as opposed to the server end.
I'll experiment between them and make up my mind.
