## Description
|
||||
|
||||
Password manager for (almost) any QMK keyboards.
|
||||
Supports cryptographic algorithms:
|
||||
Password manager for (almost) any QMK-compatible keyboards.
|
||||
It is lightweight version of `RED_CRYPTO` lib.
|
||||
|
||||
There are two versions:
|
||||
- hard-coded passwords in `keymap.c`, change branch to [`hard_coded_storage`](https://github.com/redlineo/red_crypto/tree/hard_coded_storage) or releases (YOU ARE HERE)
|
||||
- storing passwords in EEPROM with adding and editing via `RED_MENU`, change branch to [`eeprom_storage`](https://github.com/redlineo/red_crypto/tree/eeprom_storage) or releases
|
||||
|
||||
### Supports cryptographic algorithms
|
||||
|
||||
- [x] Kuznechik (Russian GOST cipher)
|
||||
- [x] SHA256 (for hashing key)
|
||||
- [ ] Streebog (for hashing key, Russian GOST hash algorithm)
|
||||
- [ ] AES256
|
||||
|
||||
## Features and plans
|
||||
### Features and plans
|
||||
|
||||
- [x] add read all ASCII-printable symbols for key
|
||||
- [x] add Kuznechik lib for non 128 bit MCU
|
||||
- [x] use SHA256 for hashing key to set key length to 32 bytes
|
||||
- [x] expand stored passwords length from 16 byte to 64
|
||||
- [x] expand number of stored passwords (manual adding new keys)
|
||||
- [ ] write new passwords to EEPROM without flashing firmware
|
||||
- [ ] add CBC mode for Kuznechik, it will increase security
|
||||
