Talk:Cryptography

message: The article's description and categorization of cryptographic hash functions is currently incorrect. Cryptographic hash functions can be used in either symmetric or asymmetric encryption and are essentially kinds of keys. The 'symmetric' vs. 'asymmetric' distinction refers to how the keys are shared, if they're shared at all. CessnaMan1989 (talk) 17:31, 7 September 2021 (UTC)
thread_title:  Cryptographic Hash Functions 

message: A few weeks year ago, technically (how time flies!), I added the sections "Applications" and "Social issues" to this article per User:Nageh's feedback on the 2011 featured article review. Though I was able to add a lot of stuff to the Applications section (and I'm we're hardly getting started!), the various applications of cryptography is a vast topic (as evidenced, for example, by the sheer size of Category:Applications of cryptography) and so deserves its own article. Therefore, I propose that this section be expanded and then split into another article titled Applications of cryptography.
I also added the section "Social issues". However, I have no idea what to put in it, so I left it blank. (Presumably, it should have enough stuff that it would have to be a mere summary of another article titled Social issues of cryptography, but that's another story.) I would ask Nageh himself, but, alas, it seems that he left Wikipedia in 2013 due to excessive wikidrama. Duckmather (talk) 18:42, 2 January 2022 (UTC)
replies: text: What is in the applications section currently is a bit light for an article, I think, and does not seem not undue here. If you or someone else were to write more content in a separate article, then one could replace the content currently here with a summary of that article. Otherwise, I would say we should just keep expanding the section here and split it when it is actually too large to remain at the main article. Felix QW (talk) 19:19, 18 November 2023 (UTC)

thread_title:  Added sections "Applications" and "Social issues" + split request 

message: Did you guys know about this code? If not, you set up a square that has five letters in a row, then you set up five rows on it. Then you place certain letters in it that has dual sounds in it, such as C, G, Y in it to replace certain other letters in it. Here is a example:
    A B C D E
    F G H I L
    M N O P Q
    R T U V W
    X Z J K Y
From this, you tap(on a excellent sound conducting surface, like a pipe), for the letter Q, tap five times, wait for one sec.,tap three times. You repeat this, only you adjust what you are doing for each letter as you spell out your words. In this one, the letter C will be used for the letter S. This was created by shot down US POWs who ended up in the Hanoi Hilton, a Viet Nam prison camp. This was in a print issue of The Readers Digest. I can't source this at this time. Some of the issues referred to what happened in Viet Nam, during the Viet Nam War, and this cipher system was in these articles. There are variations of this system, all created to confuse the Vietnamese guards. 
How is pre ISBN, pre Internet, print media sourced for Wikipedia? Thanks. Wikipedia is the best. 😘🥰 Nuclear Sergeant (talk) 09:35, 15 July 2023 (UTC)
