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 ouput 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.
