FlipdogSolutions Crypto Plugin

Flipdog Solutions, LLC

About this app

The Flipdog Encryption Plugin was built to add onto existing Flipdog Solutions applications to give them enhanced security. The current version supports the existing email application MailDroid and gives it support for S/MIME and openPGP. With openPGP, it supports Inline PGP and PGP/MIME under openPGP.

NOTE: This is a plugin library for existing Flipdog applications and will be of no use without the main application installed.

Current features are focused on MailDroid, but it will soon expand to include other Flipdog Solution apps and will improve over time. Currently, you can send email, write email and read email with PGP, and PGP/MIME as well as sMIME.

*Features*
1. Import private and public certificates for S/MIME (.crt, .cert, .cer, .pem, and .der files)
2. Import private and public keys for PGP (.asc files, PubRing.gpg, SecRing.gpg)
3. Ability to set a pass-phrase timeout
4. Certificates built into the Android Certificate Store will be recognized
5. Use self-signed certificates
6. HKP lookup and Import PGP keys
7. Set your own servers for lookup
8. View and Import from PGP server

*Permissions Explained*
1. The built in file browser needs access to read certificate files or pgp keys from your SD card in order to import them into the app.
2. The internet permission is required for S/MIME to check against the certificate authority and for the HKP implementation to look for PGP keys.
3. Logging ability is needed to send debug logs to us for support, logging is on demand and not run automatically

Ratings and reviews

S/MIME certificate cannot be imported in any format, so this app's core feature doesn't work. Might be an issue with modern android versions. This app hasn't been updated since 2015. It's a shame.

Once worked great. Not usable on Android 11 due to missing storage permission implementation as others wrote. Please update the app so I can use encryption with Maildroid again!

Not working on android 11 due to lack of new storage permission support.
