QR Code Encoder
|
||
|
|
===============
|
||
|
|
|
||
|
|
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.

Demo
|
||
|
|
====
|
||
|
|
|
||
|
|
1. Download repo and compile with `erl -make`
|
||
|
|
2. Install Google Authenticator App on your mobile:
|
||
|
|
+ iPhone: http://itunes.apple.com/us/app/google-authenticator/id388497605?mt=8
|
||
|
|
+ Android: https://market.android.com/details?id=com.google.android.apps.authenticator
|
||
|
|
3. Run demo: `qrcode_demo:run().`
|
||
|
|
4. Open the generated `qrcode.png` file
|
||
|
|
5. Scan the qrcode into the phone.
|
||
|
|
6. Ensure server clock is correct.
|
||
|
|
7. The value of `qrcode_demo:totp()` should show the same passcode as the phone.
