NAME

File::Digest - Calculate file checksum/digest (using various algorithms)

VERSION

This document describes version 0.009 of File::Digest (from Perl distribution File-Digest), released on 2019-09-12.

SYNOPSIS

 use File::Digest qw(digest_files);

 my $res = digest_files(
     files => ["file1", "file2"],
     algorithm => 'md5', # default md5, available also: crc32, sha1, sha256
 );

DESCRIPTION

FUNCTIONS

digest_file

Usage:

 digest_file(%args) -> [status, msg, payload, meta]

Calculate file checksum/digest (using various algorithms).

Return 400 status when algorithm is unknown/unsupported.

This function is not exported.

Arguments ('*' denotes required arguments):

  • algorithm => str (default: "md5")

  • digest_args => array[str]

  • file* => filename

    Filename ("-" means stdin).

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)

digest_files

Usage:

 digest_files(%args) -> [status, msg, payload, meta]

Calculate file checksum/digest (using various algorithms).

Dies when algorithm is unsupported/unknown.

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

  • algorithm => str (default: "md5")

  • digest_args => array[str]

  • files* => array[filename]

    Array of filenames (filename "-" means stdin).

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)
