Time's up for the 1K challenge and the project is still in progress. The compiled object code is nowhere near 1K, even the hex file is only 800 bytes, so size is not an inhibitor for this project. Some glitches in writing to EEPROM still exist, but they will unravel over the weekend.

The project will be finished within a week, because that's when I'll be presenting part of it at the disobey.fi conference. There will be details on the password manager that started this project in the first place too when I post links to slides after the conference on the 15th of January.
