Talk:Cryptogram

Untitled

Printed receipts from e.g. Waitrose (British supermarket) include a something labelled "cryptogram" which is a sequence of letters and numbers. It's clearly not a puzzle but perhaps some kind of credit card validation hash; does anybody have any ideas? 86.153.9.80 (talk) 17:26, 26 January 2008 (UTC)

Cryptograph Secret Key

I find this entire section inapproriate for an article about puzzles. The topic is more relevant to the science of cryptography, and I believe it's already covered there sufficiently. I would like to remove the section from the article, unless someone objects.

There are some non-relevant details in the introductory paragraph as well. The article really seems to need a cleanup.

I would agree. In fact Cryptographic_hash_function seems to cover it. -jim 10:14, 8 March 2015 (UTC)

"History" of cryptograms

Cryptograms were ... created ... in the Spartan military in fifth century B.C. This code consisted of a staff around which a strip of paper was wrapped without overlapping. A message was written on the paper, which was then unwrapped and sent on its way. The message could only be correctly decoded with the right diameter of stick.

That's not a substitution cipher. The whole section is more a history of cryptography than of cryptograms. The whole article is kind of crap. --68.40.186.209 (talk) 05:41, 5 October 2008 (UTC)

Zodiac killer

The Zodiac killer did not send cryptograms, he sent one polyalphabetic substitution cipher and 3 apparent hoaxes, and I don't see what a serial killer has to do with a wiki about a game. Skintigh (talk) 18:25, 30 May 2012 (UTC)

The sentence I changed needs reworking by someone who knows more about the topic - was it that only one of the four was translated or the specific one translated that was of no help. Jackiespeel (talk) 21:37, 24 June 2014 (UTC)
