The last paragraph:
needs work.
I do not know for sure but suspect that: block vs stream and symmetric key vs asymmetric key are orthogonal categorizations. If that is the case, changing three to four (in the offending paragraph) does not really fix the problem. — Preceding unsigned comment added by Dairiki ( talk • contribs) 00:13, 24 October 2002 (UTC)
Encryption and Cipher are currently too similar. They should be merged, or Cipher should be specialized to the customary (though vague) subset of private-key encryption. — Preceding unsigned comment added by Tromer ( talk • contribs) 05:26, 22 February 2004 (UTC)
While I'm a crypto-head and so probably biased, I do think there's a case for primary disambiguation here. I think any user typing in "cipher" is most likely to be looking for the encryption algorithm meaning, as opposed to a synonym for zero, or a Pokemon team of villains, or any of the other meanings. — Matt Crypto 11:33, 15 November 2006 (UTC)
In hebrew/arabic "sifar" ספרה means "numerical digit". Thus, given the the fact that Hebrew culture has always had interest in such subjects as Numerology, the source of the word may have also come from that direction. Bilbobugginz ( talk) 05:15, 14 July 2008 (UTC)
Encipherment does not contain enough information to stand on its own. It should be merged into this article.

Hello, hope I'm doing this right, am new at it. Just writing to suggest something. Ciphers are often said to be either transposition, or substitution, or both; but there's also one appearing in Dorothy Sayers mystery novel, "The Nine Tailors," that, strictly speaking, is neither, for it embeds the plaintext message - without substitution, and without rearrangement - within a cover message (the key being a "change ringing" method for church bells). Can't stay to pursue this, but anyone's welcome to take it up. Boinkles ( talk) 17:52, 24 August 2009 (UTC)
The article describes "codes" in the cryptographic sense as operating on the level of meaning, e.g. words; versus "ciphers", which operate on the level of characters, groups of characters, or bits. It then gives telegraph code as an example of a code. But our article on telegraph codes points to Morse code, which operates on the level of characters, as the most common one. Is something meant by "telegraph code" here other than the kind that telegraph code describes? -- Delirium ( talk) 01:25, 5 September 2009 (UTC)

Under "Modern ciphers," it is written "Figure it out. 1554-275 0 13-64799 0-0". Assuming I have no background in cryptology and have come to Wikipedia out of curiosity on this subject, where would I begin in my work to solve what is apparently meant to be an example of a cipher?

And we generate 1 initial list of minimum size of constant digits. Then we copy that list and create 20 more lists which have larger size of digits (the list two has labels which are one more digital longer than list 1, list 3 has labels which are one digit longer than list 2 etc)
Remember. Your list must be random "Uranus is my favorite planet." could be labeled as "0" and "#" could be labeled as "1". Labeling mustn't follow any logical order.
Then sometimes we introduce noise of certain digital length.
So the key could be:
34, 24, 68, 45, 13, 42 (with 68 and 42 as random insertions which have length 68 digits and 42 digits.)
34, 24, 68, 45, 13, 42 means select the labeling from the list 34 then from the list 24, add random noise for 68 digits etc.
But I didn't mention you how to "compress read" the initial text in order it fits your lists.
That method generates insanely huge files - but some prefer it.
You have to combine it with other cipher methods and make a system for list shuffling. — Preceding unsigned comment added by 2A02:2149:8464:BA00:BCE5:B794:8895:1FC4 ( talk) 15:12, 15 February 2018 (UTC)
War cipher has basic phrases and topography. Time codes and basic actions.
for example the military E-mail: "&+d" could be phrase deciphered as a huge text
In the section Types/Modern, we have symmetric key algorithms (Private-key cryptography). It looks like the links on those have gotten disambiguated or w/e to now point to the same page. Seems kinda dumb to me to have two links to the page right next to each other. Also looks like the next line has the same issue. 2600:6C55:7D00:AE4:908E:FAA4:BF3E:3601 ( talk) 23:36, 10 December 2021 (UTC)
