NAME

Digest::file - Calculate digests of files

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

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 asdigest_file(), but return the digest in hex form.
digest_file_base64( $file, $algorithm, [$arg,...] ): Same asdigest_file(), but return the digest as a base64 encoded string.
