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.
