iPGMail is an app that implements the OpenPGP standard (RFC 4880, RFC 6637) and allows the user to create and manage both public and private (RSA, DSA, ECDSA) PGP keys and send and receive PGP encrypted messages.
PGP Keys and Messages can be passed to iPGMail several ways:
* From the iOS Mail.app - The iOS mail application will pass PGP attachments to iPGMail directly, eliminating the need to do an awkward copy-and-paste. NOTE: PGP messages that are part of the main body of an email will still have to be copy-and-pasted, only properly tagged attachments can be passed automatically.
* Directly from the system clipboard. Copy-and-paste the PGP message text from any file, webpage, or message, and it can be imported and decrypted by the app.
* iTunes File Sharing - Connect your device to a computer and open up iTunes, in the "Apps" section, you can scroll down and select iPGMail under the File Sharing section and transfer files to and from the app to your computer. Make sure device is unlocked before transferring files!
* AirDrop - Transfer key files from your Mac OS/X system (10.10 or later) to your iPhone/iPad (iOS 7+) using AirDrop feature.
* DropBox - You can link iPGMail to a dropbox account and transfer files to and from your dropbox file space. This means you can encrypt and protect your dropbox files or share files with others through your existing dropbox Public interface.
* Keybase.IO - You can import public keys from http://keybase.io by using the "+" button on the public key listing and then searching for users registered in keybase.io.
iPGMail now allows you to easily reply to encrypted text-based messages and includes the original text with "> " prefixed to the lines. This allows for more email like conversational exchanges, all with strong OpenPGP cryptographic protection.
iPGMail supports PGP key generation (RSA) directly in the app and stores them securely using the iOS keychain for the application. Using your own private PGP keys, you can encrypt and/or digitally sign any messages. Optionally, your public key can be attached to any message you send from the app so that the recipient can then import it into their own keychain, either on the phone or on any computer with PGP support.
iPGMail will import your private keys so you can reuse your existing PGP identity and keys on your iPhone or iPad. Both public and private keys can be imported through the interfaces listed above.
iPGMail allows the user to search public SKS PGP keyservers to find registered public keys for other people with whom the user can then send email that is digitally signed and/or encrypted encoded in OpenPGP ASCII Armor.
This app is ideal for securing your files or for sending secure email messages to specific parties without worrying about it being viewed by anyone other than the designated recipient.
The OpenPGP standard is described here:
- updated support libraries and frameworks
- Improved crash log reporting to be more reliable. Please enable crash reporting in the settings if you are having problems!
Ratings and Reviews
Easily THE Most Advanced Cryptographic System In App Store
Phillip Zimmerman (Google the Name) put PGP together and allowed people to communicate with other people (on the internet) freely without the fear of reprisals, retaliation, prison and jail, torture, persecution, and other government sponsored “goodies” - rightfully or wrongfully!
This open coded app allows the public military level encryption. It is so powerful, once governments see its use, they/we concentrate on secondary surveillance techniques (reading the hard drives of sending or receiving computers) totally abandoning attempts to decode the message.
I worked in SIGINT (Signal Intelligence) and I use this for personal emails.
Works well, UI is a bit dated
Given the limitations of integrating security features into stock iOS apps, this works surprisingly well. It allows easy search of keyservers, import of existing public/private keys, and does most of the heavy lifting required to get a PGAp encrypted/signed email out the door.
The UI feels a bit dated, but I’m more interested in the functionality, which it delivers.
Well worth the money.
Pretty Good App ;)
Works overall. Has one minor bug where it won't prompt for the private key password until you switch away from the app to another app and then switch back. Only a pain during setup. Once your private keys are imported, tap them and enable Touch ID so you never have to enter password again.
With Family Sharing set up, up to six family members can use this app.
