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.

  • Is ultracopier still the very best in terms of open source alternative file copying/merging tool ?
    I used robocopy on a slow network to transfer many gigabyte of data; properly configured with retries and everything worked great. Don't know about your merge needs, so take a look into it and do some tests before actually running it. Source: over 1 year ago
  • Is copying the best way to transfer large amounts of files?
    If you're copying a ton of files that vary in size, using a command prompt robocopy with the multi-thread parameter can make it so you are copying multiple files simultaneously and max out the bandwidth of whatever connection you're using (usb, SATA, ethernet, etc). Source: over 1 year ago
  • Game data to new PC
    This would probably work well. Oblivion mod managers edit load order by modifying dates on the files, and I'm not sure if dragging-and-dropping would keep that info. Source: over 1 year ago
  • Migrating file servers - Robocopy syntax question
    Yes, /mir also deletes files and directories that have been deleted from the source. Here's a list of the switches. Source: almost 2 years ago
  • Robocopy Hell - Copy data without NTFS permissions
    My friend you helped me big time. I was able to test more and the U flag on /COPY was the culprit here. Which isn't a huge deal for me so using /COPY:DAT worked great. Turns out this is the default switching for /COPY anyway according to https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/robocopy. Source: almost 2 years ago
