FreeOTP Extractor

A quick and dirty tool to take the backup XML file from FreeOTP and convert the tokens stored within to QR codes/OTP urls.

Released under the Apache 2.0 license -- please note that several files are taken from different sources, so their individual copyright notices must be maintained.

Usage

target/freeotp-extractor-1.0-SNAPSHOT.jar <backup xml (in sp folder)>

URLs will be output to the command line, and QR codes will be saved to a images/ folder in the current directory. This could be made configurable but I stopped once I got far enough to get my tokens back.

Known Issues

There are many -- please fix them if you care

• output directory is not configurable
• HOTP tokens are not supported (the tURI method in Token was using Android classes, so it was very quickly rewritten. i do not use HOTP tokens so I didn't take the time to fix them.)
• Very limited error handling. Be ready for stacktraces.
• File names may contain invalid characters on Windows
