### 3/5 — Encryption Error keeps showing

*2026-08-27*

When I first got the app, everything worked smooth during my tests.. 

Recently I tried to encrypt a message to a contact that I have encrypted to before and now it keeps saying error unsupported symmetric Id 10

But again it was working with the same contact a few days ago...

Not sure what changed but it doesn't work anymore

**Developer response:** Thanks for the detail, especially the exact error text. It pointed straight at the cause.

This isn't something you did, and it isn't your message. It's that contact's key. "Unsupported symmetric Id 10" means their encryption key now lists Twofish as one of its settings, and this build only accepts AES there, so it stops instead of guessing. It worked a few days ago because their key has changed since then, most likely a key update or refresh on their end.

This is a bug on my side, and I've made a change that should let PGPony encrypt to that contact again in the next update. If you'd like to fully test it against that exact key before or after it ships, email me at NorseHorse@norsehor.se and I'll get you a build and confirm it works.

Thanks again for reporting it so clearly.

### 5/5 — Yubikey Support

*2026-08-29*

I’ve been waiting forever for an iOS PGP app with Yubikey support. I finally found PGPony and I really like it for so much more than Yubikey. The design is nice and clean, well thought out. Bonus on top is native keygen support for newer ECC keys.
