NAME

       Digest::MD5::File - Perl extension for getting MD5 sums for files and urls.

SYNOPSIS

           use Digest::MD5::File qw(dir_md5_hex file_md5_hex url_md5_hex);

           my $md5 = Digest::MD5->new;
           $md5->addpath('/path/to/file');
           my $digest = $md5->hexdigest;

           my $digest = file_md5($file);
           my $digest = file_md5_hex($file);
           my $digest = file_md5_base64($file);

           my $md5 = Digest::MD5->new;
           $md5->addurl('http://www.tmbg.com/tour.html');
           my $digest = $md5->hexdigest;

           my $digest = url_md5($url);
           my $digest = url_md5_hex($url);
           my $digest = url_md5_base64($url);

           my $md5 = Digest::MD5->new;
           $md5->adddir('/directory');
           my $digest = $md5->hexdigest;

           my $dir_hashref = dir_md5($dir);
           my $dir_hashref = dir_md5_hex($dir);
           my $dir_hashref = dir_md5_base64($dir);

DESCRIPTION

         Get MD5 sums for files of a given path or content of a given url.

EXPORT

       None by default.  You can export any file_* dir_*, or url_* function and anything
       Digest::MD5 can export.

          use Digest::MD5::File qw(md5 md5_hex md5_base64); # 3 Digest::MD5 functions
          print md5_hex('abc123'), "\n";
          print md5_base64('abc123'), "\n";

OBJECT METHODS

   addpath()
           my $md5 = Digest::MD5->new;
           $md5->addpath('/path/to/file.txt')
               or die "file.txt is not where you said: $!";

       or you can add multiple files by specifying an array ref of files:

           $md5->addpath(\@files);

   adddir()
       addpath()s each file in a directory recursively. Follows the same rules as the dir_*
       functions.

           my $md5 = Digest::MD5->new;
           $md5->adddir('/home/tmbg/')
               or die "See warning above to see why I bailed: $!";

   addurl()
           my $md5 = Digest::MD5->new;
           $md5->addurl('http://www.tmbg.com/tour.html')
               or die "They Must Be not on tour";

file_* functions

       Get the digest in variouse formats of $file.  If file does not exist or is a directory it
       croaks (See NOFATALS for more info)

           my $digest = file_md5($file) or warn "$file failed: $!";
           my $digest = file_md5_hex($file) or warn "$file failed: $!";
           my $digest = file_md5_base64($file) or warn "$file failed: $!";

dir_* functions

       Returns a hashref whose keys are files relative to the given path and the values are the
       MD5 sum of the file or and empty string if a directory.  It recurses through the entire
       depth of the directory.  Symlinks to files are just addpath()d and symlinks to directories
       are followed.

           my $dir_hashref = dir_md5($dir) or warn "$dir failed: $!";
           my $dir_hashref = dir_md5_hex($dir) or warn "$dir failed: $!";
           my $dir_hashref = dir_md5_base64($dir) or warn "$dir failed: $!";

url_* functions

       Get the digest in various formats of the content at $url (Including, if $url points to
       directory, the directory listing content).  Returns undef if url fails (IE if
       LWP::UserAgent's $res->is_success is false)

           my $digest = url_md5($url) or warn "$url failed";
           my $digest = url_md5_hex($url) or warn "$url failed";
           my $digest = url_md5_base64($url) or warn "$url failed";

SPECIAL SETTINGS

   BINMODE
       By default files are opened in binmode. If you do not want to do this you can unset it a
       variety of ways:

           use Digest::MD5::File qw(-nobin);

       or

           $Digest::MD5::File::BINMODE = 0;

       or at the function/method level by specifying its value as the second argument:

           $md5->addpath($file,0);

           my $digest = file_md5_hex($file,0);

   UTF8
       In some cases you may want to have your data utf8 encoded, you can do this the following
       ways:

           use Digest::MD5::File qw(-utf8);

       or

           $Digest::MD5::File::UTF8 = 1;

       or at the function/method level by specifying its value as the third argument for files
       and second for urls:

           $md5->addpath($file,$binmode,1);

           my $digest = file_md5_hex($file,$binmode,1);

           $md5->addurl($url,1);

           url_md5_hex($url,1);

       It use's Encode's encode_utf8() function to do the encoding. So if you do not have Encode
       (pre 5.7.3) this won't work :)

   NOFATALS
       Instead of croaking it will return undef if you set NOFATALS to true.

       You can do this two ways:

           $Digest::MD5::File::NOFATALS = 1;

       or the -nofatals flag:

           use Digest::MD5::File qw(-nofatals);

           my $digest = file_md5_hex($file) or die "$file failed";

       $! is not set so its not really helpful if you die().
