NAME

6       Digest::file - Calculate digests of files
7

SYNOPSIS

9         # Poor mans "md5sum" command
10         use Digest::file qw(digest_file_hex);
11         for (@ARGV) {
12             print digest_file_hex($_, "MD5"), "  $_\n";
13         }
14

DESCRIPTION

16       This module provide 3 convenience functions to calculate the digest of
17       files.  The following functions are provided:
18
19       digest_file( $file, $algorithm, [$arg,...] )
20           This function will calculate and return the binary digest of the
21           bytes of the given file.  The function will croak if it fails to
22           open or read the file.
23
24           The $algorithm is a string like "MD2", "MD5", "SHA-1", "SHA-512".
25           Additional arguments are passed to the constructor for the
26           implementation of the given algorithm.
27
28       digest_file_hex( $file, $algorithm, [$arg,...] )
29           Same as digest_file(), but return the digest in hex form.
30
31       digest_file_base64( $file, $algorithm, [$arg,...] )
32           Same as digest_file(), but return the digest as a base64 encoded
33           string.
