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 RapidCRC Unicode and Jacksum.

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

  • whenever i try to download a bigger game I always get this message. how can I fix this?(more info in comments)
    Sounds like a fake SD card? E.g. a 16 GB card that was modded to look like a 128 GB card. You should check the card on a PC. Copy some big files onto the card and compare the checksums (CRC32, MD5, ...) of the original files with the ones on the SD card with a tool like RapidCRC (https://ov2.eu/programs/rapidcrc-unicode).
