SYNOPSIS

        package foo;
        use Meta::Digest::MD5 qw();
        my($md5)=Meta::Digest::MD5->new();
        my($digest_file)=$md5->get_filename_digest("/etc/passwd");

DESCRIPTION

This module extends the functionality found in the Digest::MD5 standard module with code that otherwise will have to be written many times in places of Digest::MD5. The object inherits from Digest::MD5 so you can use all of that modules functionality too. I try very hard not to override existing MD5 methods.

FUNCTIONS

        get_filename_digest($)
        get_filename_hexdigest($)
        get_filename_b64digest($)
        TEST($)

FUNCTION DOCUMENTATION

get_filename_digest($)

This method adds a file name to the current Meta::Digest::MD5 object. The reason we use the object oriented methodology here (creating an object and then adding the file using the addfile method) is that it could be that this method is much more memory effective since we don't have to load the entire blob to memory at one time as we would do if we had uploaded everything and then used the "md5" method of the package.

get_filename_hexdigest($)

Same as get_filename_digest but returns the result in hex.

get_filename_b64digest($)

Same as get_filename_digest but returns the result in base 64.

TEST($)

Test suite for this module.

SUPER CLASSES

Digest::MD5(3)

BUGS

None.
