Crypt-in is in active development, and the developer beta is live since 29 September 2026.
Current package: beta-2026-10-30, published 30 October 2026. It adds New identity to the app, the guided cure for G2. It changes the app and the updater only — the firmware is byte-for-byte the one ofbeta-2026-10-13. If your dongle already runsbeta-2026-10-13, replace the app folder:nothing to flash, no transfer. See the security advisory.
The developer beta is live since 29 September 2026. All downloads are free for beta participants, and the beta licence runs until 31 March 2027 — renewed free if the beta continues.

cryptin-beta-2026-10-30-1001.zip — SHA25648dbed35d3826ecd899ff15f5af25e8c72518fdd64f744466c45b21648e2cd43. The hashes of the six files inside the archive are published separately, on the release page: six OK lines, five is not a pass. The archive name carries the build time and the tag the publication date — both on 30 October 2026. beta-2026-10-14 stays on GitHub as history, marked superseded.
The beta is one package: Windows client, updater, flashing tool and firmware. The SDK and the Linux CLI are not in it, and have no announced date.
Every component of the firmware and of the CLI is declared in the Software Bill of Materials → — SPDX 2.3, published before the binaries ship. The Windows client, Personal v1, has no SBOM of its own yet.
The -dev build for ESP32-S3, inside the beta package. It is not signed: Secure Boot v2 is not active on beta units, so there is no signature to check. Verify it byhash instead, against SHA256SUMS.txt — see the Flash Guide.
Personal v1 — file encryption into .crin containers.
One Apache 2.0 package: Windows DLL plus the .NET 9 CLI for Linux and macOS. The CLI is part of CryptinSDK, not a separate download. HID protocol client and .crin utilities. The CLI has not shipped: it was not in the beta package, and no date has been announced.
Windows encrypted file manager. €50 one-time — available at public launch, April 2027.
Complete, and already public — the links below work today.
Published as a beta: github.com/jaffa2970/cryptin-sdk-beta since 17 October 2026 — no support, and no issues or pull requests during the beta. It is a separate release: this package still ships binaries only. The firmware is never part of it: it stays closed source, and the beta build is the unsigned -dev image.
SPDX 2.3, one document per artefact. Every component is declared and independently verifiable.
On Linux, libudev and OpenSSL stay system dependencies — DEPENDS_ON, not CONTAINS. Details and CVE guidance on the SBOM page.
Reviewing the architecture is exactly the kind of feedback that is useful now. General questions: info@lake8.dev. Vulnerabilities: security@lake8.dev, under the disclosure policy.
