Take it as extra low priority issue, but it may be nice to have support for MIDP 1.0 devices. For make this work, only small fixes are needed:

I think the Bouncy Castle version should be OK. Only a few classes is used. And the WTK emulator (MIDP-1.0 configured) seems to be fine with that.

@jfriesse Could you review the changes in the MIDP-1.0-compatible branch please? If it's OK, I'll merge it to master. Thanks in advance.

@kwart Changes seems to be ok. If you can provide me binaries, I can test on real HW if you like.

@jfriesse The SNAPSHOT is uploaded to http://sourceforge.net/projects/totpme/files/test/, if you are able to test it, it would be helpfull. Thank you.

@kwart I've installed SNAPSHOT to MIDP-1.0 device (Nokia 6100). Results:

Application starts without problem
Key generator works
Key is properly stored and restored on new start
Other values (Time correction, HMAC algorithm, Number of digits and Time step) are correctly stored and restored on new start
Token is visible, it's updating regularly
Gauge (timer) is visible and correctly respects Time Step value
Menu items are correctly ordered (device have only 2 menu hw buttons, so it's preferable to display Exit and let Options + Key generator under Menu)

So from my point of view, application works perfectly.

Thanks again for quick resolution.

@jfriesse Thanks a lot for the tests. I've merged the branch into the master and I'll release it in 1.3.Final soon.
