edit · history · watch · refresh Stock post message.svg To-do list for MD5:

  • Summarise results of Berson
  • Complete the (non-pseudocode) description of the MD5 algorithm
  • Add information about md5x one step to double md5 hashes
Priority 3

Acronym MD[edit]

Acronym MD The following text was added to the lead by NetBlues on 12 January 2017 (diff):

The MD5 hash function receives its acronym MD from its structure using Merkle–Damgård_construction.

Computer people are well known for enjoying humor and there well may be a backronym explanation for what "MD" means, but given MD4 (which has the same unsourced claim diff) and RFC 1321 a good source for that assertion is needed. The text should be removed from here and MD4 if no reference is available. Johnuniq (talk) 23:46, 13 February 2017 (UTC)

The acronym MD actually refers to the term Message Digest, rather than Merkle–Damgård_construction. While Merkle–Damgård_construction is used in MD5, I could not substantiate that it was used in any previous iterations of MD* algorithms, leading me to now believe that there is no correlation between the names, and the acronyms for each are a coincidence. My original assertion is withdrawn. NetBlues (talk) 15:27, 20 September 2017 (UTC)

External links modified[edit]

Hello fellow Wikipedians,

I have just modified one external link on MD5. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

When you have finished reviewing my changes, you may follow the instructions on the template below to fix any issues with the URLs.

As of February 2018, "External links modified" talk page sections are no longer generated or monitored by InternetArchiveBot. No special action is required regarding these talk page notices, other than regular verification using the archive tool instructions below. Editors have permission to delete these "External links modified" talk page sections if they want to de-clutter talk pages, but see the RfC before doing mass systematic removals. This message is updated dynamically through the template {{sourcecheck}} (last update: 15 July 2018).

  • If you have discovered URLs which were erroneously considered dead by the bot, you can report them with this tool.
  • If you found an error with any archives or the URLs themselves, you can fix them with this tool.


Cheers.—InternetArchiveBot (Report bug) 14:43, 10 January 2018 (UTC)

Figure wrong[edit]

The figure uses the part of the message Mi.

But in the code and the RFC it is Mg with g either i, (5i + 1) mod 16, (3i + 5) mod 16 or (7i) mod 16.

Additionally the rotation of inside the figure should be si an not s only

I cannot correct the wrong Mi in figure but maybe someone else can.--158.64.4.213 (talk) 10:10, 15 March 2019 (UTC)
