PGPro can encrypt and decrypt messages as well as manage all your OpenPGP keys. It is free, simple and lightweight. Everything stays on your device. PGPro is made in Switzerland.

Hello lucanaef,

i want to try your PGPro app to use GPG encryption on my iOS 14.1 device. Unfortunatly i failed to import my GPG private and public key. Reason was "Unsupported Key".

I have generated my keys using the following command on a debian buster system:

gpg --quick-gen-key "Name <email>" ed25519 cert 2y
gpg --quick-add-key [keyid] cv25519 encr 1y
gpg --quick-add-key [keyid] ed25519 auth 1y
gpg --quick-add-key [keyid] ed25519 sign 1y

I use the following version of GnuPG

gpg (GnuPG) 2.2.12
libgcrypt 1.8.4

Do you have an idea if i make anything wrong, or is this "state of the art" key really not supportes? If second, will/can support for this kind of key be available in the near future?

Kind regards Oliver Koch

The OpenKeychain QR code simply contains a plaintext string with the format OPENPGP4FPR:<Fingerprint>.

Here's an example of the generated QR code for Edward, an email bot from the FSF to test email encryption (as in emailselfdefense.fsf.org).

OPENPGP4FPR:F357AA1A5B1FA42CFD9FE52A9FF2194CC09A61E8.

Adding the ability to scan the QR code would be a great way to instantly add another public key without the need of manually enter an email or the fingerprint into the app. This can be done by:

1. Scanning the QR code
2. Check whether the payload is valid
3. Search signature on keyservers

The OpenKeychain app also uses this functionality to verify confirm other public keys, if the current private key is capable of confirming other keys (aka. unstripped).

I got the issue that I can’t import a key pair one after another. First the pub key and then the priv key e.g. just one of them. Preproduction with any key pair. iPhone 8 13.4.1 App Version. 2020.02

Hi, could you include in the description/documentation where the private keys are stored and how access to them is secured ? It's quite sensitive to upload a private key, without knowing where it is going ...

Great job anyway ! Thanks !

Hello,

I come across this project and would like to get started with it, but unfortunately all the Xcode project files is gitignored. Can you please share why? At the moment I wasn't able to find any reasoning neither in git history, nor on the website. It seems to be added just the second commit to the repo.

Gitignore file seems to be autogenerated and it is too broad – repo obviously does not contain swift package library, but it has spm artifacts gitignored as well. Xcode gitignore section contains both reasonable lines (like xcuserdata) and also lines I find unreasonable to gitignore (like xcodeproj).

In my opinion, whole Xcode section should be discarded and SwiftPM section too, but Swift section kept. In my projects, I usually only have this much:

# Mac OS X
.DS_Store

# Backup files
*~.nib

# Xcode
build/*
*.pbxuser
!default.pbxuser
*.mode1v3
!default.mode1v3
*.mode2v3
!default.mode2v3
*.perspectivev3
!default.perspectivev3
*.xccheckout
xcuserdata
profile
*.moved-aside
DerivedData
*.xcscmblueprint

# AppCode
.idea

Would you mind sharing xcodeproj (and xcworkspace if any) with the rest of the world please?

Thanks for making PGPro, I think it is a long missing addition to the iOS ecosystem. However I got one problem: when I receive an encrypted mail sent from Thunderbird 78.3.2 and forward it to PGPro from the built-in iOS Email app, PGPro fails to decrypt it. The error msg is simply "Decryption failed!". I can decrypt other PGP blocks and tracked down the error to the fact, that PGP blocks generated as above are missing an empty line after the line "-----BEGIN PGP MESSAGE-----". This only seems to be the case when I directly forward the "encrypted.asc" MIME attachment from the iOS EMail app to PGPro. When I somehow get the attachment into a text editor and from there copy&paste it to PGPRo, decryption works. Needless to say, the latter is extremely inconvenient on an iOS device ... :-)

Hi @lucanaef,

I've come across what seems to be, in my estimation, a low-severity security issue.

Can you provide me with your pubkey and email for further dialog on this topic?

Thanks, Jonathan

Edit: Alternatively, you can reach out to me directly via the contact info on my profile.

Hi, first: great move to create an open source app for iOS for PGP encrypten/decryption ! That was needed !

When editing a message for encryption, it is not easily possible to hide the keypad again to access the bottom controls bar. Any simple common way to hide the keypad (selecting a public key does it ... but it's not so intuitive.

This PR converts all naked strings that are used for display into NSLocalizedStrings, and generates the xcloc file for en locale. Currently no additional locale is added, but it unlocks adding future locales.

Hopefully this solves the concern of #76 and paves the way for #88

Might just be a user error as this seems to be too a basic functionality to not be working, but still. Here's my error and how to reproduce:

1. I have an encrypted e-mail in the Apple Mail app. I have clicked on the encrypted message attachment (encrypted.asc) and click on PGPro in the share screen.
2. So far so good. The encrypted content is displayed in the Decryption window, I can select my key and enter my passphrase. I click on the open envelope on the top right and:
3. The app just shuts down and when I restart all the details are gone.

Am I doing something wrong? Is there something wrong with my key? The same key works on macOS Mail using GPGTools.

Some things I've tried:

• Manually pasting encrypted contents
• Entering a wrong password (get an error message, so I'm using the right one)

Using an iPhone 12, iOS 15.0.1

Let me know if I can provide you with anything or try anything. Thank you for this!

Hi,
could not run the app in iOS v12.4.x iPhone-6.

this app or AppStore shows message (after or during install), that,
iOS v13 or above is needed.
:(

Please enable support for iOS v12.4.x / v12 (when time-permits to do so).
i'm sure, lots of users still using iPhone-6.

I have been using http://keyoxide.org/ for identify verification, and it makes use of OpenPGP profile notations for identity claims. Details can be found here: https://docs.keyoxide.org/openpgp-profiles/using-gnupg/#Adding_an_identity_claim. I was wondering if it would be possible to add support for this feature?

First off, thank you very much for this great app! I got an error after trying to send you an e-mail on [email protected] Recipient address rejected: Address does not exist so I'll just ask here: I encounter an issue, not being able to read the content of an encrypted message. In Mail I open the encrypted.asc file and send it to PGPro. In the settings I enable undor Preferences “Mail Integration” but still no luck. I can read a bit of the headers but nothing of the e-mails content is being decrypted. Any idea how to solve this?

I’m on an iPhone SE 2022, iOS 15.6.1 and the latest version of your app, 2021.4

Thank you in advance.

Would it be possible to add a way to export the file into a QR that is animated?

And then also import that data back into the app from access to photos?

When importing a private key, the app is loading and using the expired key rather than the unexpired key. The keys are listed in gpg --list-packets in this order:

cv25519 (encryption) [expired] ed25519 (signing) [expired] rsa4096 (signing) [valid] rsa4096 (encryption) [valid] rsa4096 (authentication) [valid]

Also note that importing the public keys via paste or file has the same issue. Importing the public key via key server works as expected.

Another key set works as expected, though the EC keys are valid and also listed first.
