Comment:
{{{
18:13 < mvngu> rbeezer: The output of brute_force() is all the 312
possible
dicipherments.
18:14 < mvngu> rbeezer: It uses a list of list for an indexing scheme
that's
meant for readability.
18:14 < rbeezer> but I'm not getting the keys that achieves them
18:14 < rbeezer> the L list is a list of empty lists??
18:14 < mvngu> rbeezer: Let me upload my recent patches....
18:14 < rbeezer> aah, that'd help ;-) ;-)
18:18 < mvngu> rbeezer: Uploaded patches.
18:18 < mvngu> rbeezer: Note the ticket dependency.
18:19 < rbeezer> thanks - do they include whatever prompted you to take
the
ticket back to "needs work"
18:19 < mvngu> rbeezer: yes
18:19 < rbeezer> In other words, should I attempt a full review in the
next 6
hours, or no?
18:19 < mvngu> rbeezer: I fixed some documentation typos, add an example
on the
decimation cipher.
18:20 < mvngu> rbeezer: And yes, I think it's ready for a full review.
18:20 < mvngu> rbeezer: Thank you very much for spending time on these
crypto
stuff!
