References #466

Adds operation for extracting hash values from text blocks. Searches text for hashes based on length.
Options for:

  • Searching for hashes of all lengths. Potential hash lengths taken from "Analyse Hashes" operation.
  • Displaying total hashes found.

If it makes more sense to select hash types by name from a dropdown rather than by character length, I can change that.

I'm loving the number of people who are still around 5 years later. Apologies it took so long to get to this!

Please could you add some unit tests. This would help ensure we are extracting the correct hashes in the future!

No problem! I've added some unit tests.

const regex = new RegExp(`(\\b|^)[a-f0-9]{${hashCharacterLength}}(\\b|$)`, "g");
const searchResults = search(input, regex, null, false);

hashCount += searchResults.split("\n").length - 1;

This area crashed for me when I tested it out. I've made some changes to hopefully resolve the issues I saw. Could you verify it works for you as well?
