Crypt-in is currently in active development. Developer beta launches 30 September 2026.
Developer beta launches 30 September 2026. All downloads are free for beta participants, and the beta licence runs until 31 March 2027 — renewed free if the beta continues.
Firmware, Windows client, and Linux CLI (coming September 2026) will all be available at the developer beta launch.
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.
Signed binary for ESP32-S3. Always verify the signature before flashing — 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. CLI arrives 30 September 2026 — fallback 30 October.
Windows encrypted file manager. €50 one-time — available at public launch, April 2027.
Complete, and already public — the links below work today.
The SDK repository opens at developer beta launch:github.com/lake8dev/cryptin-sdk. It does not exist yet — the link is intentionally not clickable. The firmware is never part of it: it stays closed source and ships as a signed binary.
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 before the beta is exactly the kind of feedback that is useful now. General questions: info@lake8.dev. Vulnerabilities: security@lake8.dev, under the disclosure policy.
