Version 6.2.1 fixes Face ID prompting for signing and decrypting with hardware keys, plus stability improvements.

Version 6.2.0 brings RSA support to hardware security keys. If you carry a YubiKey 5 NFC or a Token2, you can now use an RSA key on it the same way ECC keys already worked: Sign messages on the card Encrypt and sign, including encrypting a copy to yourself Decrypt messages sent to your card's RSA key Change a key's expiration date right on the card It all happens over NFC with a PIN and a tap, and everything interoperates with GnuPG. This rounds out hardware key support so RSA users get the same first-class treatment as everyone else, alongside PGPony's existing OpenPGP v6 (RFC 9580) compatibility. Also in this release: The Decrypt screen's key list is now a searchable picker. It still finds the right key for a message on its own, defaults to the key you use most, and pins your hardware keys to the top. A clearer, larger Paste button when you import a key. Thanks for using PGPony.

When you create your first key during setup, you can now choose between Ed25519 (v4) and the newer OpenPGP v6 format. If you're not sure which to pick, go with v4 for the widest compatibility. iCloud Keychain sync now picks up keys from your other devices without making you relaunch the app. Sync stays off until you turn it on in Settings, so your keys only follow you across devices if you want them to. Also fixed an issue where saving a key that was already synced could fail.

Full OpenPGP v6 support lands in this release. Complete v6 (RFC 9580) workflow: generate v6 keys, encrypt, decrypt, sign, verify, and now revoke them, all interoperable with Sequoia PGP and GnuPG. Generate v6 revocation certificates when a key is compromised, retired, or superseded. Customize the Comment header embedded in your armored PGP output, write your own, keep the default, or turn it off, from Settings. Import GnuPG v4 keys (EdDSA) directly, with passphrase-protected keys supported for signing and decrypting. Scan v6 and v4 keys by QR code, and import keys found through keyserver search. Encrypt files in app and sign with any key; passphrase-protected keys now prompt for the passphrase when signing. Fixes and polish, including a more reliable Share Public Key sheet. Thanks for using PGPony. As always, everything is free.

Version 6.0 brings hardware security keys to PGPony. ▸ Hardware security keys: tap an NFC OpenPGP card like a YubiKey or Token2 to sign and decrypt with a private key that never leaves the card ▸ Add a hardware key to your keyring with a single tap that links it to your public key ▸ Sign on the card three ways: detached signatures, clear-signed messages, and encrypt-and-sign ▸ Messages you decrypt on your card now show the signature banner naming the signer ▸ Change your hardware key PIN right in the app ▸ New Card Details view: manufacturer, serial number, the algorithm in each key slot, creation dates, and remaining PIN attempts ▸ Decrypt hardware-key messages from the Share Sheet, with a hand-off to the app to finish the card tap ▸ Bigger, clearer Paste buttons on Encrypt and Decrypt ▸ Better PIN entry for cards that use letters and symbols, not just numbers Everything is still free. No accounts, no tracking, no data collection. Questions or feedback? NorseHorse@norsehor.se

This update introduces a refreshed app icon. Everything you rely on — secure key generation, encryption, and GnuPG compatibility — works exactly as before. Thanks for using PGPony!

Version 5.0 is the biggest PGPony update yet, focused on signing, verifying, key discovery, and revocation. Signing and verifying New "Sign" mode on the Encrypt tab produces clear-signed messages that anyone with your public key can verify, no encryption needed. Perfect for posts, emails, or files where you want to prove authorship without hiding the contents. Every decrypted message now shows a signature banner with four states: verified by a known signer (green), invalid (red), unknown signer (yellow), or unsigned (grey). Clear-signed messages pasted into Decrypt auto-detect and verify. Tap any yellow "unknown signer" banner to search keys.openpgp.org for the signer's public key, review their identity, and import in one step. The banner refreshes to green without re-decrypting. "Sign as" picker on the Encrypt screen lets you choose which key pair signs outgoing messages when you have more than one. Native Ed25519 signing path verified bit-perfect against GnuPG. Both v4 and v6 signatures supported. Finding keys Looking up a recipient by email now tries Web Key Directory at their own domain first, then falls back to keys.openpgp.org. Keys served from the recipient's own infrastructure are preferred over third-party keyservers. Lookup by fingerprint accepts full v4, full v6, and long key ID formats. Key lifecycle Generate a revocation certificate for any of your key pairs from the Danger Zone in Key Details. Importing the cert in any PGP tool marks the key as revoked. Per-key private key export with full GnuPG compatibility for Cv25519 encryption subkeys. Subkey graph for every key, with proper capability tracking (sign / encrypt / certify / authenticate). First v5.0 launch runs a one-time migration showing brief progress. Languages PGPony now ships in English, German, Spanish, French, Japanese, and Brazilian Portuguese. Switch languages anytime from Settings. Fixes and polish Uploading public keys to keys.openpgp.org now uses the correct request format. First-visit tooltips dismiss permanently on the first interaction instead of reappearing. The App Store review prompt now waits until you've had several successful encryptions or decryptions, and never appears during onboarding, after errors, or after invalid signature verifications. Reliability improvements to clear-signed verification and message decryption. PGPony's privacy model is unchanged: your private keys live in iOS Keychain on this device and never leave it.
