NAME

Digest::file - Calculate digests of files

SYNOPSIS

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

DESCRIPTION

This module provide 3 convenience functions to calculate the digest of files. The following functions are provided:

digest_file( $file, $algorithm, [$arg,...] )

This function will calculate and return the binary digest of the bytes of the given file. The function will croak if it fails to open or read the file.

The $algorithm is a string like "MD2", "MD5", "SHA-1", "SHA-512". Additional arguments are passed to the constructor for the implementation of the given algorithm.

digest_file_hex( $file, $algorithm, [$arg,...] )

Same as digest_file(), but return the digest in hex form.

digest_file_base64( $file, $algorithm, [$arg,...] )

Same as digest_file(), but return the digest as a base64 encoded string.
