| burn-btc: create a bitcoin burn address | |
| By James C. Stroud | |
| This program requries base58 (https://pypi.python.org/pypi/base58/0.2.1). | |
| Call the program with a template burn address as the only argument:: |
| ### Last tested February 7 2014 on a Galaxy S3 (d2att) running Cyanogenmod 11 nightly, with Google Authenticator 2.49. | |
| ### Device with Google Authenticator must have root. | |
| ### Computer requires Android Developer Tools and SQLite 3. | |
| ### Connect your device in USB debugging mode. | |
| $ cd /tmp | |
| $ adb root | |
| $ adb pull /data/data/com.google.android.apps.authenticator2/databases/databases |
