Updated the app’s PGP component and related dependencies.

- Organize Contacts with tags, making it easier to manage friends, teams, and groups. - When encrypting, add recipients from a tag in one step, then review and adjust the final recipient list before creating the message. - Contact details now make key history easier to review. - Requires iOS, iPadOS, macOS, or visionOS 26.5 or later.

This version completes the planned App Data Protection work for this stage. More local app data, including Contacts and everyday preferences, is now kept in encrypted storage that opens only after you unlock CypherAir.

This update continues our work toward broader on-device app data protection, with the protection framework still being actively refined and expanded. It also improves the Biometrics Only app access experience when authentication is locked by the system, providing clearer guidance and a smoother retry flow. On macOS, this release improves privacy screen behavior around system authentication prompts for a more stable unlock experience.

This update adds Apple arm64e support, improves authentication, strengthens private-key recovery, and begins rolling out stronger protection for CypherAir app data. Before updating, please back up your private keys and any important CypherAir data. This version includes automatic migration changes for local protection data. In rare cases, migration may not complete as expected and could cause problems. - Adds Apple arm64e support on compatible Apple devices. - Begins rolling out stronger protection for app data. This work is still in progress and will continue in future updates. - Improves Face ID, Touch ID, and Optic ID authentication when unlocking CypherAir or changing security modes. - Makes private-key recovery more resilient if a security change or key update is interrupted. - Reduces cases where system authentication appears repeatedly. Some cases may still remain, and we will continue improving this. - Improves security boundaries and recovery behavior across the app.

This update adds a new contact certificate signature tool. You can now verify certificate signatures, check User ID bindings, and generate User ID certification signatures directly from a contact’s detail page. CypherAir remains open source and is now licensed under the GNU General Public License v3.0 or later (GPL-3.0-or-later) or the Mozilla Public License 2.0 (MPL-2.0). We also fixed a UI issue where stale content could remain after importing binary signature files, and improved localization and overall polish in several areas.

This update brings official native support to Apple Vision Pro and improves signature details, revocation tools, contact handling, and reliability across CypherAir. CypherAir now officially supports visionOS, bringing a native Apple Vision Pro experience to the app. Verification and decryption now show more detailed signature results, including multiple signatures and clearer warnings for unknown, expired, or invalid signers. Added Selective Revocation, so you can export a revocation signature for a single subkey or a single User ID without modifying the key stored in CypherAir. Re-importing a contact certificate with the same fingerprint now updates identities, subkeys, and revocation status more reliably, and revocation certificate export works more consistently for imported and existing keys. Improved the Guided Tutorial launch experience on macOS.

This update improves contact certificate updates, revocation certificate generation and export, and detached file verification. - Re-importing a contact certificate with the same fingerprint now updates identities, subkeys, and revocation status more reliably. - Improved revocation certificate generation and export, including for imported keys and existing keys that need revocation data to be created on demand. - Fixed an issue where cancelling detached file verification could cause it to hang.

This update brings improvements to the Guided Tutorial and a reliability fix for key deletion. Clearer tutorial guidance and a smoother sandbox walkthrough. Better onboarding handoff into the tutorial experience. Fixed a rare issue where temporary pending key data might not be fully removed when deleting a key.

Add Guided Tutorial

This update improves the experience for armored text files: - You can now import encrypted.asc directly in Decrypt > Text - You can now import signed.asc directly in Verify > Cleartext - Opening text-based encrypted messages is now smoother and more intuitive
