Some scripts used when handling messages on http://enigmaworldcodegroup.freeforums.net

Here are some scripts that I use when handling messages on http://enigmaworldcodegroup.freeforums.net The scripts can handle both finding a key for a existing text and pick a key for a new message. They key format given is pasted in to meinEnigmas serial api.

It is two scripts for the two procedures M3 and M4(triton). Included are also keysheet for the past and future

Disclaimer: It has bugs so don't blindly accept the output, verify that it looks resonable. This is specially important for odd cases or when you getting keys for days other than today.

Usage:
================================================================
# On it's own it will prep the start of a new message
./GenKeyM3.sh
