Cloned from komone/qrcode.
Only qrcode generating module included in this repository. The demo module and identification modules were removed.
Reference used was ISO/IEC 18004, 1st Edition (2000)
This implementation is informed by my specific needs, i.e. to provide two-factor authentication for mobile phones running Google Authenticator.
- "Byte" mode only (don't need e.g. numeric mode or kanji mode).
- Encode only (no detection/decode).
- Basic supporting library functions provided (HOTP, PNG image functions) to allow full-cyle demo.
NOTE: This documentation is rather basic as this was open-sourced by specific request!
