Jacksum supports 489 algorithms, including the most common cryptographic and non-cryptographic hash functions. Jacksum also supports the "Rocksoft (tm) Model CRC Algorithm" to customize your CRC.

Jacksum can perform a verification of hashes against a set of known hashes, and it can detect matching, non-matching, missing, and new files.

Jacksum takes advantage of modern multi-processor/multi-core environments, and saves time by hashing multiple files in parallel, and by computing hashes with multiple algorithms in parallel.

Output can occur in predefined standard formats (BSD-, GNU/Linux-, or Solaris style, SFV or FCIV) or in a user-defined format which is highly customizable, including many encodings for representing hash values, including binary, decimal, octal, hexadecimal with lowercase or uppercase letters, Base16, Base32 with and without padding, Base32hex with and without padding, Base64 with and without padding, Base64url with and without padding, BubbleBabble, and z-base-32.

Input data can come from files, standard input stream (stdin), or provided directly by command line arguments.

Jacksum supports many charsets for reading and writing files properly, and it comes with full support for all common Unicode aware charsets such as UTF-8, UTF-16, UTF-16BE, UTF-16LE, UTF-32, UTF-32BE, UTF-32LE, GB18030, etc.

With Jacksum you can also find the algorithm used to calculate a checksum, CRC, hash or find files that match a given hash value.

DocFetcher Reviews

  1. Pros, Cons

    I love DocFetcher! I discovered this gem of a program when Windows stopped supporting string searches in word processors other than Word.

    ๐Ÿ Competitors: the generic string search available in Windows, Agent Ransack, Locate32, Everything by Voidtools
    ๐Ÿ‘ Pros:    Beautiful intuitive interface. easy to use, once you set up the index.
    ๐Ÿ‘Ž Cons:    If you have a large collection of files to index, you will eventually be unable to search all your documents at the same time. you have to set up separate indexes and search each one separately. available in a variety of versions, up to 64 bit.|The help files are good. however, learning how to set up an index can be frustrating.

  • Tool to parse, index, and search local documents? - Windows
    I use https://docfetcher.sourceforge.net/en/index.html to index and search large repos of docs. I use Papermerge for my digital file cabinet though. DocFetcher is good for searching an existing repository of files. Source: about 1 year ago
  • Docfetcher is a cross-platform free and open source desktop search application
    As they state, it is crap-free, free forever, cross-platform, portable, private (local only), and indexes only what you need. You can also set minimum and maximum file sizes to index. See https://docfetcher.sourceforge.net/en/index.html. Source: over 1 year ago
  • Career Advice for a fresh graduate who wants to enter Structural Engineering field
    What I'd recommend is setting up a digital and/or physical technical library. Download any useful documents, books, standards etc. and store them in a clear, concise folder structure. Then create an index of the library with a tool like DocFetcher. (Think of it as Google for your technical library) This should make it fast and easy to find the relevant information when you need it. Source: over 1 year ago

  • How do you organize yourself?
    I use Outlook for e-mail and calendars. I use Evernote to store my notes. I also have a folder in Dropbox called "docs" where I store TXT (and others like DOCX and PDF etc) files for tasks/projects like the cisco firmware update example. I use DocFetcher (https://docfetcher.sourceforge.net/en/index.html) to perform search on the stored notes in TXT / DOCX / PDF / etc. Source: over 1 year ago
