Hey, so I need a list of Spanish surnames and place names etc., but when I look
online, google tells me that there are plenty of baby names to chose from, or
I can download a gazetteer as a set of scanned images from an old book.
So, do any participants from Spain or South/central America have a list of
Spanish names in plain text format? I would appreciate it, as it would go a
long way towards helping me to conquer the world.5th October 2022 at 8:41 pm #85326BreakTheCipherParticipant

I just found a neat way to crib a Hill cipher. If you find the inverse of a matrix composed of ciphertext vectors,
and multiply that by a matrix of plaintext, you get a transpose of the key, or something like that. I managed to
get it working for an 8×8 Hill cipher. Here is a link to a paper about Hill ciphers and about the technique:
p.s. I found the Spanish word I was looking for.11th December 2022 at 2:21 pm #87524HeirToTheSpareParticipant
Hey Harry/Madness/Anyone who seems like an expert on ciphers.
I need help. What is the best way to get better at ciphers? Are there certain useful/helpful websites for a beginner-slash-intermediate person to read and learn from (regarding ciphers, cryptanalysis, etc.)? Books? Ahh! I don’t really know how to enunciate my struggles.
I just don’t really understand how we’re supposed know how to crack the later challenges. Is it a coding thing? How much do we have to know about ciphers to do so? Like – HOOW?11th December 2022 at 5:48 pm #87533madnessParticipant
@Heir, I put (almost) everything I knew 2 years ago into a very long document. It can be found in the BOSS library or
in the training materials, I forget which. And a good book is Gaines, Cryptanalysis. Only $14 on Amazon. Don’t know the price in metric.
[Gaines’ book is out of copyright and now available as a pdf in the library. Just click on the cover! Harry]
