PGPKit

PGPKit is PGP for people who want it to work.

Send an encrypted message to anyone who uses GnuPG, Thunderbird, Proton Mail or OpenKeychain. Read what they send back. Check that a message really came from who it says. Every operation happens on your phone — there is no account, no server, and no analytics.

INTEROP YOU CAN COUNT ON

PGPKit is tested against four independent OpenPGP implementations — GnuPG, Sequoia, RNP (the engine inside Thunderbird) and GopenPGP (the engine inside Proton). Keys it creates are standard OpenPGP v4, readable everywhere.

PASTE ANYTHING

Copy an encrypted message from any mail app and tap Paste, or open an .asc file. PGPKit repairs the damage mail apps do — stray quote marks, broken line endings, extra spaces — and works out whether it is a message, a signature or a key.

ERRORS THAT MAKE SENSE

Instead of "decryption failed", PGPKit tells you what happened and what to do: the message was encrypted to a different key, the passphrase is wrong, the file was damaged in transit.

YOUR KEYS NEVER GET LOST

Creating a key walks you straight into a backup, protected by a passphrase you choose, and verified by opening it again before you save it. The backup is a standard OpenPGP file that GnuPG can open too.

FINGERPRINT OR FACE INSTEAD OF TYPING

Choose to remember a key's unlock and your fingerprint or face opens it in an instant. The unlocked key is protected by an Android Keystore key that only a biometric match can release — never synced, never backed up.

PRIVATE BY DESIGN

• Keys are encrypted by the Android Keystore and excluded from Google backups

• No account, no analytics, no ads, no crash reporting

• No version line or device details in anything you send; the one-line “Made with PGPKit” note switches off in Privacy & Data

• Works offline
