K9 mail integration Love it! Being able to send PGP encrypted signed mails is a great feature for mobile. The only reason people say the keys """"""""""""""""aren't secure"""""""""""""""" is a limitation of mobile hardware. Supposedly the entropy collection on mobile devices is inferior to that of traditional hardware. If you're that concerned  generate the keys on your desktop and import them like I did. Also  storing keys on your phone is considered a security risk. Small request though. SHA512 signature support?""
