Data::Printer::Filter:UsereContributed Perl DoData::Printer::Filter::Digest(3)

NAME
       Data::Printer::Filter::Digest - pretty-printing MD5, SHA	and many other
       digests

SYNOPSIS
       In your ".dataprinter" file:

	   filters = Digest

       You may also setup the look and feel with the following options:

	   filter_digest.show_class_name = 0
	   filter_digest.show_reset	 = 1

	   # you can even customize your themes:
	   colors.digest = #27ac3c

       That's it!

DESCRIPTION
       This is a filter	plugin for Data::Printer. It filters through several
       message digest objects and displays their current value in hexadecimal
       format as a string.

   Parsed Modules
       Any module that inherits	from Digest::base. The following ones are
       actively	supported:

       o   Digest::Adler32

       o   Digest::MD2

       o   Digest::MD4

       o   Digest::MD5

       o   Digest::SHA

       o   Digest::SHA1

       o   Digest::Whirlpool

       If you have any suggestions for more modules or better output, please
       let us know.

   Extra Options
       Aside from the display color, there are a few other options to be
       customized via the "filter_digest" option key:

       show_class_name

       If set to true (the default) the	class name will	be displayed right
       next to the hexadecimal digest.

       show_reset

       If set to true (the default), the filter	will add a "[reset]" tag after
       dumping an empty	digest object. See the rationale below.

   Note	on dumping Digest::* objects
       The digest operation is effectively a destructive, read-once operation.
       Once it has been	performed, most	Digest::* objects are automatically
       reset and can be	used to	calculate another digest value.

       This behaviour -	or, rather, forgetting about this behaviour - is a
       common source of	issues when working with Digests.

       This Data::Printer filter will not destroy your object. Instead,	we
       work on a cloned	version	to display the hexdigest, leaving your
       original	object untouched.

       As another debugging convenience	for developers,	since the empty	object
       will produce a digest even after	being used, this filter	adds by
       default a "[reset]" tag to indicate that	the object is empty, in	a
       'reset' state - i.e. its	hexdigest is the same as the hexdigest of a
       new, empty object of that same class.
