NAME

       GnuPG::Tie::Encrypt - Tied filehandle interface to encryption with the GNU Privacy Guard.

       GnuPG::Tie::Decrypt - Tied filehandle interface to decryption with the GNU Privacy Guard.

SYNOPSIS

	   use GnuPG::Tie::Encrypt;
	   use GnuPG::Tie::Decrypt;

	   tie *CIPHER, 'GnuPG::Tie::Encrypt', armor => 1, recipient => 'User';
	   print CIPHER <<EOF;
       This is a secret
       EOF
	   local $/ = undef;
	   my $ciphertext = <CIPHER>;
	   close CIPHER;
	   untie *CIPHER;

	   tie *PLAINTEXT, 'GnuPG::Tie::Decrypt', passphrase => 'secret';
	   print PLAINTEXT $ciphertext;
	   my $plaintext = <PLAINTEXT>;

	   # $plaintext should now contains 'This is a secret'
	   close PLAINTEXT;
	   untie *PLAINTEXT;

DESCRIPTION

       GnuPG::Tie::Encrypt and GnuPG::Tie::Decrypt provides a tied  file handle interface to encryption/decryption facilities of the GNU Privacy
       guard.

       With GnuPG::Tie::Encrypt everyting you write to the file handle will be encrypted. You can read the ciphertext from the same file handle.

       With GnuPG::Tie::Decrypt you may read the plaintext equivalent of a ciphertext. This is one can have been written to file handle.

       All options given to the tie constructor will be passed on to the underlying GnuPG object. You can use a mix of options to output directly
       to a file or to read directly from a file, only remember than once you start reading from the file handle you can't write to it anymore.

NAME

       Tie::RefHash - use references as hash keys

SYNOPSIS

	   require 5.004;
	   use Tie::RefHash;
	   tie HASHVARIABLE, 'Tie::RefHash', LIST;
	   tie HASHVARIABLE, 'Tie::RefHash::Nestable', LIST;

	   untie HASHVARIABLE;

DESCRIPTION

       This module provides the ability to use references as hash keys if you first "tie" the hash variable to this module.  Normally, only the
       keys of the tied hash itself are preserved as references; to use references as keys in hashes-of-hashes, use Tie::RefHash::Nestable,
       included as part of Tie::RefHash.

       It is implemented using the standard perl TIEHASH interface.  Please see the "tie" entry in perlfunc(1) and perltie(1) for more
       information.

       The Nestable version works by looking for hash references being stored and converting them to tied hashes so that they too can have
       references as keys.  This will happen without warning whenever you store a reference to one of your own hashes in the tied hash.

EXAMPLE

	   use Tie::RefHash;
	   tie %h, 'Tie::RefHash';
	   $a = [];
	   $b = {};
	   $c = *main;
	   $d = "gunk";
	   $e = sub { 'foo' };
	   %h = ($a => 1, $b => 2, $c => 3, $d => 4, $e => 5);
	   $a->[0] = 'foo';
	   $b->{foo} = 'bar';
	   for (keys %h) {
	      print ref($_), "
";
	   }

	   tie %h, 'Tie::RefHash::Nestable';
	   $h{$a}->{$b} = 1;
	   for (keys %h, keys %{$h{$a}}) {
	      print ref($_), "
";
	   }

THREAD SUPPORT

       Tie::RefHash fully supports threading using the "CLONE" method.

STORABLE SUPPORT

       Storable hooks are provided for semantically correct serialization and cloning of tied refhashes.

RELIC SUPPORT

       This version of Tie::RefHash seems to no longer work with 5.004. This has not been throughly investigated. Patches welcome ;-)
