Digest::file - phpMan

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.
