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.
