NAME File::Digest - Calculate digests of files VERSION This document describes version 0.011 of File::Digest (from Perl distribution File-Digest), released on 2019-11-29. SYNOPSIS use File::Digest qw(digest_files); my $res = digest_files( files => ["file1", "file2"], algorithm => 'md5', # default md5, available also: crc32, sha1, sha256 ); DESCRIPTION This module provides some convenience when you want to use Digest against files. FUNCTIONS digest_file Usage: digest_file(%args) -> [status, msg, payload, meta] Calculate digest of file. 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 digests of files. 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) HOMEPAGE Please visit the project's homepage at .
