Digest::file(3)
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.
