Hash Generator and Validation Tool VS Jacksum

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.

Questions and Answers

As answered by people managing Hash Generator and Validation Tool 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
10 predefined styles for reading and writing files that contain hash values
8600+ lines of manpage with descriptions, examples, and compatibility lists for the most common algorithms
