Tillitis Key (TKey) is a new kind of USB security token. What makes
the TKey unique is that it allows a user to load and run applications on
the device, while still providing security. This allow for open-ended,
flexible usage. Given the right application, the TK1 can support use
flexible usage. Given the right application, the TKey can support use
cases such as SSH login, Ed25519 signing, Root of Trust, FIDO2, TOTP,
Passkey, and more.

The Tkey platform is based around a 32-bit RISC-V processor and has
128 KB of RAM. The current firmware is designed to load an app that is
up to 100 KB in size, and gives it a stack of 28 KB. A smaller app may
move itself in memory to get larger continuous memory.

hardware for its security-critical operations.
All of the Tkey software, firmware, FPGA Verilog source code, schematics
