Tillitis

Tillitis is a Swedish publisher that concentrates on minimalist, hardware-based cryptographic tools built around its open-source TKey USB security device; by combining a small programmable RISC-V secure element with firmware that can be reflashed in seconds, the company offers developers and privacy-minded users a tangible root of trust for everyday workflows. The TKey SSH Agent replaces conventional software key rings by generating and storing SSH credentials inside the dongle, eliminating the risk of leaked private keys while still supporting agent forwarding and pin-protected log-ins on Windows, macOS, or Linux. TKeySign extends this concept to document integrity, letting engineers, lawyers, and open-source maintainers create detached Ed25519 signatures that can be verified by anyone who knows the corresponding public key, thereby simplifying release signing or audit trails without relying on cloud CAs. Finally, TKeyVerification provides a lightweight utility to confirm that a specific TKey is genuine and to bind its unique identity to a user or service, a step often required when onboarding team members to sensitive repositories or when provisioning sealed-hardware build farms. All three utilities are command-line driven, integrate cleanly with existing Git, SSH, and CI pipelines, and are released under permissive licenses that encourage auditing and community contribution. Tillitis software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always install the latest upstream builds, and can be queued for batch deployment across multiple machines.
