# Digest::file(3p)

Calculate digests of files

## 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.
