- 17:1817:18, 29 July 2023 diff hist +655 Talk:Rainbow table →Key stretching or key strengthening doesn't protect against rainbow tables: new section Tag: New topic
7 June 2023
- 09:4109:41, 7 June 2023 diff hist −37 m Exclusive or merged sentences
- 09:3809:38, 7 June 2023 diff hist +2 m Exclusive or wrong type of italics, used markdown
- 09:3709:37, 7 June 2023 diff hist +64 Exclusive or included either A or B as language construct
5 July 2022
- 15:1515:15, 5 July 2022 diff hist +9 m Elliptic Curve Digital Signature Algorithm fixed link to IETF (using RFC-editor as indicated by IETF themselves)
27 May 2022
- 02:5702:57, 27 May 2022 diff hist +298 Talk:BLS digital signature →Attacks not listed: new section
13 July 2021
- 10:1710:17, 13 July 2021 diff hist +31 m SHA-3 →Hardware acceleration: changed final sentenced due to various grammar, spelling and logical mistakes (didn't look at validity of claims)
23 February 2021
- 10:0810:08, 23 February 2021 diff hist +551 Talk:Oblivious transfer →Oblivious transfer "importance of applications": new section
6 February 2021
- 15:0715:07, 6 February 2021 diff hist 0 m ESP32 Fixed UART description to make preview feature work - syntax only change
4 January 2021
- 00:3600:36, 4 January 2021 diff hist +13 Block cipher mode of operation cleared up that ciphertext (stealing in this case) is specific to CBC mode
- 00:2800:28, 4 January 2021 diff hist −5 Block cipher mode of operation "Simplified CFB" is not a well known term, and Googling it will just bring up this page. So I've changed it to full-block CFB which is much more common and is more descriptive.
28 March 2020
- 15:3115:31, 28 March 2020 diff hist +41 Cryptographic hash function →Verifying the integrity of messages and files: any attacker can create an HTTPS site, just having the connection secured doesn't prevent change of the hash output - the site (name) needs to be authentic / trusted Tags: Mobile edit Mobile web edit
2 March 2020
- 11:0911:09, 2 March 2020 diff hist +520 Talk:Lamport signature →Incorrect citation for Winternitz signature compression: new section
28 December 2019
- 16:4916:49, 28 December 2019 diff hist −805 Christian state Removed part about fertility rates and the role of the Patriarch on it as it seems to fall out of thin air and seems off topic here. If it is returned the text should clarify why it is there in the first place.
5 November 2019
- 00:2300:23, 5 November 2019 diff hist +101 Wim Jonk fixed sentences, changed summary block as well
- 00:1800:18, 5 November 2019 diff hist +167 Wim Jonk added current employment, easily verified by looking at the page of FC Volendam of course or the club page itself
5 August 2018
- 15:2315:23, 5 August 2018 diff hist +4,728 Cryptographic hash function →Cryptographic hash algorithms: Added actual section actually listing algorithms, created "Attacks on cryptographic hash algorithms" containing most of the previous section under the same name. Added some references to the attack section. Removed "The SHA-3 competition" section as it is too specific (just follow SHA-3 link)..
- 12:4612:46, 5 August 2018 diff hist 0 m Cryptographic hash function →Password verification: just capitalized the p of password hashing to make the page more consistent
- 12:4112:41, 5 August 2018 diff hist −304 Cryptographic hash function →As building block for other algorithms: Deleted, as it is already mentioned down below in a separate section: https://en.wikipedia.org/wiki/Cryptographic_hash_function#Use_in_building_other_cryptographic_primitives
- 12:3712:37, 5 August 2018 diff hist +76 Cryptographic hash function →Pseudorandom generation and key derivation: Removed already mentioned password hashing, introduced HMAC where it is indeed just a building block (other MAC algos exist that use a block cipher). Referenced CSPRNG for existing example.
- 12:2712:27, 5 August 2018 diff hist +39 Cryptographic hash function →Signature generation and verification: added "main article" part
- 12:2412:24, 5 August 2018 diff hist +582 Cryptographic hash function →Verifying the integrity of files or messages: Explained how storing hashes on the (org.) website help establish integrity (it's not for the files stored next to the hashes). Reversed some sentences and removed fluff (like "for example" etc.). Gave digital signatures a separate section, still relying on the previous section that explains message integrity. Tried to use "hash digest" as generic term to describe the output of the hash. Explained hash + chain of trust vs CRC error code..
- 11:2511:25, 5 August 2018 diff hist −790 Cryptographic hash function →Password verification: Strongly simplified text as this is about cryptographic hashes, not password hashes. Removed inaccuracies: salt is commonly not *just* concatenated with the password in a PBKDF and should just be considered input to a password hash, not as an input of a cryptographic hash. bcrypt doesn't use a hash function (it uses the Blowfish block cipher) so mentioning it here is wrong. The long text about Argon2 is not suitable here; it belongs on a page about Argon2.
13 May 2018
- 14:0714:07, 13 May 2018 diff hist +38 m Quadratic residue →Cryptography: Included link to computational hardness problem in wikipedia itself as it wasn't explained
24 February 2018
- 14:0214:02, 24 February 2018 diff hist −1 m Helmand Province →Transport and economy: formatting of sentence, repeat of earlier info btw
- 14:0114:01, 24 February 2018 diff hist −1 m Helmand Province changed sub flower to sunflower - that's all folks Tag: Visual edit
8 May 2016
- 18:0018:00, 8 May 2016 diff hist −218 User:Owlstead ←Blanked the page current
29 November 2015
- 15:3215:32, 29 November 2015 diff hist +685 Talk:Elvis operator →Kotlin does have an Elvis operator: new section
17 October 2015
- 14:2914:29, 17 October 2015 diff hist +728 Elvis operator Put languages in "Usage" similar to https://en.wikipedia.org/wiki/%3F: (ternary operator ? x : y) and added Kotlin example / reference
9 October 2015
- 11:5611:56, 9 October 2015 diff hist +110 42 (number) →Television and film: added reference to Finding Nemo
18 September 2015
- 14:0714:07, 18 September 2015 diff hist +879 Talk:Fermat number →Moving Generalized Fermat Numbers to a separate article: new section
28 June 2015
- 16:2616:26, 28 June 2015 diff hist +647 VIA Technologies →VIA PadLock: added the other security functionality offered by VIA on select processors
26 May 2015
- 18:0018:00, 26 May 2015 diff hist −394 Pseudorandom number generator Undid revision 659025958 by 31.55.127.252 (talk) - Although Random.java is indeed in Java, so is SecureRandom which is a hash based SPRNG by default. Java does not *rely* on Random.java
18 April 2015
- 10:5810:58, 18 April 2015 diff hist +20 Pseudorandom number generator It has not been proven as such that a backdoor actually exists - but it's pretty likely
- 10:4910:49, 18 April 2015 diff hist −228 Pseudorandom number generator Removed link without any reference from the text, this seems more like a ad than anything else (even if the site linked to is not using any ads itself)
- 10:4610:46, 18 April 2015 diff hist −394 Pseudorandom number generator Removed Java reference. Java doesn't rely on Random as PRNG, not for ages *if ever*. For PRNG you have to use SecureRandom instances, not Random instances.
29 May 2014
- 16:4916:49, 29 May 2014 diff hist −104 Onyx Undid revision 610665397 by Owlstead (talk) - but using same picture for agate and onyx is confusing
- 16:4516:45, 29 May 2014 diff hist +104 Onyx added inline comment (I hope)
3 January 2013
- 15:3115:31, 3 January 2013 diff hist +104 WS-Security padding oracle attack
- 15:2415:24, 3 January 2013 diff hist +915 Padding oracle attack added more general description, added link on padding oracle attack on OAEP padding mode for (e.g.) RSA
- 14:5714:57, 3 January 2013 diff hist +55 WS-Security →added more info for padding oracle attacks
- 14:5414:54, 3 January 2013 diff hist +452 WS-Security →Issues
28 December 2012
- 15:1315:13, 28 December 2012 diff hist +275 Padding (cryptography) →Added explanation when zero padding may be applied
- 15:0315:03, 28 December 2012 diff hist +644 Padding (cryptography) →Added part about padding oracle attacks for symmetric ciphers
- 14:4614:46, 28 December 2012 diff hist +109 Padding (cryptography) →Grammar and general make-up, changed PKCS#1 v2.0 to v1.5 as this refers to a padding mode *within* the PKCS#1 v1.5 to v2.1 specifications
- 14:3714:37, 28 December 2012 diff hist +43 m Padding (cryptography) →Gramatical changes, added hash to PKCS#5 and PKCS#7
- 14:3314:33, 28 December 2012 diff hist −412 Padding (cryptography) →Removed opinion "dated" for the Merkle-Damgård construction; removed unsubstantiated, unreadable description of extension attacks, added link to wiki instead
- 14:2114:21, 28 December 2012 diff hist +91 Padding (cryptography) →Removed unnecessary paragraph, added definition of bit padding and byte padding.
- 14:1314:13, 28 December 2012 diff hist −1 m Padding (cryptography) →decapitalized "symmetric-key encryption algorithms
- 14:1114:11, 28 December 2012 diff hist −307 Padding (cryptography) →Generalized the paragraph and removed unnecessary (and incorrect) examples of bit padding and PKCS#5 padding and PKCS#7 padding. Removed unsubstantiated ref. to timing attacks.
