Dekey Version 1.xx by Mikero
see readmeGeneral and fixes
Dekey checks the integrity of .bisign, .bikey, and .biprivatekey files.
It does not crack them open as such, merely checks their validity.
Dekey is most useful in doing a full folder scan looking for version ONE bisigns versus the shinier version 2's. A bonus for sysops
dekey [-P] whatever.bisign | bikey | privatekey
-P don't pause
0: no errors (includes version2 bisigns)
1: version 1 (old) bisign
