There's no public key encryption for Android yet, but that's an important feature for many of us. APG tries to fill that void, with new features quickly being added. Hopefully APG will grow into a fully functional OpenGPG implementation of GPG or PGP calibre.

NOTE: requires Android 1.5+

Hey, upload your APK to FDroid or Github, not just Google Drive.

I don't want to get Google account. http://impurist.com/contact.php?m=39386

we use Thunderbird with GPG4WIN and K9 with APG on mobile. We often have the issue that on mobile the mails are not decrypted and the mail is just shown as attachement. We assume it is because of some MIME issues. Also the attachments are not encrypted by K9/APG.

Suggestion: Why not start a crowd funding so you get some budget to program a feature rich version?

Best regards, Jens

Please add password protection to your app.

If I lost my phone, someone can open APG can see public/private keys!

I second "GoogleIsShit"'s comment. Please make the apk available on FDroid. I am glad you are developing this.

Thank you.

PS @GoogleIsShit: Can you not make a special key just for your phone that you can nullify once you phone is stolen?
