[HOE] Decryption

[toadpooka@juno.com]

My players recently came into possession of 3 data slugs that contain
heavily encrypted NA military data.  Now they're trying to find someone
or something in Junkyard that can decode them enough to find out what's
on there (the players fear that the slugs contain the locations of
unexploded City-Busters).  They want to hide the data from everyone they
can (the only groups deemed "worthy" so far are Ike and the Chamber)
until they figure this out.
My question is: does anyone have any ideas about how to do this in-game? 
Would the decryption equipment be hardware (junker-built AI or Brains
machine) or software (data slugs).
I generally do want them to succeed at getting this stuff, but it
shouldn't be too simple to actually do...
