Ratings and Reviews
Has potential, but not for people already with private keys
I think this app has potential, but it has a number of flaws that makes it unusable for my personal use.
Pros:
- The user interface is lovely. It feels modern and is pretty to look at, which is something I can’t say about many other similar apps.
- The key creation works well. It makes it easy to share the public key with the openpgp key server and provides a QR code for the fingerprint of the key.
- One can also export their public key to a file and import it elsewhere (such as through GnuPG)
- The Share Extension makes it very easy to decrypt messages: you can highlight the encrypted text, then share it to the Pignus, where it will decrypt and display the message.
Cons:
- I did not manage to import any of my own private keys. I tested this with both RSA 3072 and ED25519 keys and the application immediately crashed. This issue alone makes the application useless to people that already use PGP.
- I couldn’t import my public key from the keyserver, or as a file.
- There isn’t an ability to sign messages - you can only encrypt.
- I couldn’t find a way to revoke my key. This is very important for security and is absolutely needed.
- No obvious way to change keyserver.
- There are also no options to change the type of key, or how it’s generated. You can only use RSA3072. The generated keys also don’t expire, which maybe be for simplicity, but is a security risk.
In summary, whilst the application looks nice, it lacks basic functionality that means people already invested in PGP won’t be able to use the application. I’m hoping that some of these issues will be addressed as the app is one of the only ones of its type with a nice user interface!
doesn’t work
crashes on startup, did work for week or so then nothing.
