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.

As answered by people managing Jacksum and Md5Checker.

What makes your product unique?

Jacksum's answer

Jacksum (JAva ChecKSUM) is a free, open source, cross-platform, feature-rich, multi-threaded command line utility that makes hash functions available to you. It covers many types of use cases where hash values are needed:

  • Calculating of hash values of almost any input
  • Finding OK/failed/missing/new files (verify file/data integrity)
  • Finding files by their fingerprints for positive matching
  • Finding files that do not match certain fingerprints for negative matching
  • Finding all duplicates of a file by its hash value
  • Finding the algorithm(s) that generated a certain hash value

In order to achieve the goals above Jacksum supports you with

  • 489 standard hash functions
  • Customizable CRCs from 1 to 64 bit width
  • 60+ options to control Jacksum's behavior on the command line
  • 14 standard encodings for representing hash values
  • 10 predefined styles for reading and writing files that contain hash values

  • File Integrity and checksums
    You can use Teracopy to copy folders / files with verification after copy. It produces checksums of the source and destination files that can optionally get saved to disk. You can also use Teracopy to validate these saved checksums. Another (freeware) utility that you can use to produce / verify checksums on individual folders / files is Md5Checker.

  • No files after sync on iPod 📱 i need help !?
    Test everything by eliminating all the possible reasons. First, test SD card with something like h2testw program without the adapter. Second, test CF-SD adapter with the same card via CF card reader. Third, sync only small portion of tracks, like 50-100, and check if sync was successful. Fourth, select one of the tracks in iPod_Control\Music hidden folder on iPod and compare it to the original in your library with... Source: about 1 year ago
  • I officially need help emulating the Sega CD
    If you've done everything according to the wiki (bios file names are case sensitive and should only need to go inside the \BIOS\ folder), take a look at the official core documentation here you can find the checksum values for the correct Bios and use an app like MD5Checker to verify.

  • Does this not exists? Checksum program...
    I’m sure there are dozen more of apps but some of the few I use: Md5Checker, Teracopy (which also copies with verification) and checkpoint. Source: almost 2 years ago
  • Error -6
    Here is possible that your download was corrupted. Download Md5Checker from http://getmd5checker.com/. Check iso file with it. Md5 checksum should be: c64cdf16381323980ec6a3f37b8b8087. If different you have bad file. If is the same then boot in windows safe mode + disable antivirus (defender) + run setup as admin. Source: about 2 years ago
