App::xsum - Compute and check file checksums/digests (using various algorithms)
This document describes version 0.002 of App::xsum (from Perl distribution App-xsum), released on 2019-08-21.
See xsum.
Usage:
xsum(%args) -> [status, msg, payload, meta]
Compute and check file checksums/digests (using various algorithms).
xsum is a small handy utility that can be used as an alternative/replacement for the individual per-algorithm Unix utilities like md5sum, sha1sum, sha224sum, and so on. It's basically the same as said Unix utilities but you can use a single command instead.
xsum
md5sum
sha1sum
sha224sum
The backend of xsum is a Perl module File::Digest which in turn delegates to the individual per-algorithm backend like Digest::MD5, Digest::SHA, and so on. Most of the backend modules are written in C/XS so you don't suffer significant performance decrease.
This function is not exported.
Arguments ('*' denotes required arguments):
algorithm => str (default: "md5")
check => bool
Read checksum from files and check them.
files* => array[filename]
tag => bool
Create a BSD-style checksum.
Returns an enveloped result (an array).
First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.
Return value: (any)
