use Crypt::GPG;
  my $gpg = new Crypt::GPG;

$gpg->gpgbin('/usr/bin/gpg');      # The GnuPG executable.
  $gpg->secretkey('0x2B59D29E');     # Set ID of default secret key.

=head1 DESCRIPTION

The Crypt::GPG module provides access to the functionality of the
GnuPG (www.gnupg.org) encryption tool through an object oriented
interface.

It provides methods for encryption, decryption, signing, signature
verification, key generation, key certification, export and
import. Key-server access is on the todo list.

This release of the module may create compatibility issues with
previous versions. If you find any such problems, or any bugs or
documentation errors, please do report them to
crypt-gpg at neomailbox.com.

=head1 CONSTRUCTOR

=over 2

=item B<new()>

Creates and returns a new Crypt::GPG object.

=back

=head1 DATA METHODS

=over 2

=item B<gpgbin($path)>

Sets the B<GPGBIN> instance variable which gives the path to the GnuPG
binary.

=item B<gpgopts($opts)>

Sets the B<GPGOPTS> instance variable which may be used to pass
additional options to the GnuPG binary. For proper functioning of this
module, it is advisable to always include '--lock-multiple' in the
GPGOPTS string.

=item B<delay($seconds)>

Sets the B<DELAY> instance variable. This is no longer necessary (nor
used) in the current version of the module, but remains so existing
scripts don't break.

=item B<secretkey($keyid)>

Sets the B<SECRETKEY> instance variable which may be a KeyID or a
username. This is the ID of the default key to use for signing.

=item B<passphrase($passphrase)>

Sets the B<PASSPHRASE> instance variable, required for signing and
decryption.

=item B<text($boolean)>

Sets the B<TEXT> instance variable. If set true, GnuPG will use
network-compatible line endings for proper cross-platform
compatibility and the plaintext will gain a newline at the end, if it
does not already have one.

=item B<armor($boolean)>

Sets the B<ARMOR> instance variable, controlling the ASCII armoring of
output. The default is to use ascii-armoring. The module has not been
tested with this option turned off, and most likely will not work if
you switch this off.

=item B<detach($boolean)>

Sets the B<DETACH> instance variable. If set true, the sign method
will produce detached signature certificates, else it won't. The
default is to produce detached signatures.

=item B<encryptsafe($boolean)>

Sets the B<ENCRYPTSAFE> instance variable. If set true, encryption
will fail if trying to encrypt to a key which is not trusted. This is
the default. Turn this off if you want to encrypt to untrusted keys.

=item B<version($versionstring)>

Sets the B<VERSION> instance variable which can be used to change the
Version: string on the GnuPG output to whatever you like.

=item B<comment($commentstring)>

Sets the B<COMMENT> instance variable which can be used to change the
Comment: string on the GnuPG output to whatever you like.

=item B<nofork($flag)>

Sets the B<NOFORK> instance variable which if set to a true value will
cause keygen() not to fork a separate process for key generation.

=item B<debug($boolean)>

Sets the B<DEBUG> instance variable which causes the raw output of
Crypt::GPG's interaction with the GnuPG binary to be dumped to
STDOUT. By default, debugging is off.

=back

=head1 OBJECT METHODS

=over 2

=item B<sign(@message)>

Signs B<@message> with the secret key specified with B<secretkey()>
and returns the result as a string.

=item B<decrypt(\@message, [\@signature])>

This is just an alias for B<verify()>

=item B<verify(\@message, [\@signature])>

Decrypts and/or verifies the message in B<@message>, optionally using
the detached signature in B<@signature>, and returns a list whose
first element is plaintext message as a string. If the message was
signed, a Crypt::GPG::Signature object is returned as the second
element of the list.

The Crypt::GPG::Signature object can be queried with the following
methods:

$sig->validity();    # 'GOOD', 'BAD', or 'UNKNOWN'
   $sig->keyid();       # ID of signing key
   $sig->time();        # Time the signature was made
   $sig->trusted();     # Signature trust level

=item B<msginfo(@ciphertext)>

Returns a list of the recipient key IDs that B<@ciphertext> is
encrypted to.

=item B<encrypt($plaintext, $keylist, [-sign] )>

Encrypts B<$plaintext> with the public keys of the recipients listed
in B<$keylist> and returns the result in a string, or B<undef> if
there was an error while processing. Returns undef if any of the keys
are not found.

Either $plaintext or $keylist may be specified as either an arrayref
or a simple scalar.

If $plaintext is a an arrayref, it will be join()ed without
newlines.

If you want to encrypt to multiple recipients, you must use the
arrayref version of $keylist. A scalar $keylist works for only a
single key ID.

If the -sign option is provided, the message will be signed before
encryption. The secret key and passphrase must be set for signing to
work. They can be set with the secretkey() and passphrase() methods.

=item B<addkey($key, $pretend, @keyids)>

Adds the keys given in B<$key> to the user's key ring and returns a
list of Crypt::GPG::Key objects corresponding to the keys that were
added. $key may be a string or an array reference.

If B<$pretend> is true, it pretends to add the key and creates the key
object, but doesn't actually perform the key addition.

Optionally, a list of key IDs may be specified. If a list of key IDs
is specified, only keys that match those IDs will be imported. The
rest will be ignored.

=item B<export($key)>

Exports the key specified by the Crypt::GPG::Key object B<$key> and
returns the result as a string.

=item B<keygen($name, $email, $keytype, $keysize, $expire, $passphrase)>

Creates a new keypair with the parameters specified. The only
supported B<$keytype> currently is 'ELG-E'. B<$keysize> can be any of
1024, 2048, 3072 or 4096. Returns undef if there was an error,
otherwise returns a filehandle that reports the progress of the key
generation process similar to the way GnuPG does. The key generation
is not complete till you read an EOF from the returned filehandle.

=item B<certify($keyid, $local, @uids)>

Certifies to the authenticity of UIDs of the key with ID $keyid. If
$local is true, the certification will be non-exportable. The @uids
parameter should contain the list of UIDs to certify (the first UID of
a key is 0).

=item B<keydb(@keyids)>

Returns an array of Crypt::GPG::Key objects corresponding to the Key
IDs listed in B<@keyids>. This method used to be called B<keyinfo> and
that is still an alias to this method.

=item B<parsekeys(@keylist)>

Parses a raw GnuPG formatted key listing in B<@keylist> and returns an
array of Crypt::GPG::Key objects.

=item B<keypass($key, $oldpass, $newpass)>

Change the passphrase for a key. Returns true if the passphrase change
succeeded, false if not, or undef if there was an error.

=item B<delkey($keyid)>

Deletes the key specified by the Crypt::GPG::Key object B<$key> from
the user's key ring. Returns undef if there was an error, or 1 if the
key was successfully deleted.

=item B<disablekey($keyid)>

Disables the key specified by the Crypt::GPG::Key object B<$key>.

=item B<enablekey($keyid)>

Enables the key specified by the Crypt::GPG::Key object B<$key>.

Error checking needs work.

=item *

Some key manipulation functions are missing.

=item *

The method call interface is subject to change in future versions.

=item *

The current implementation will probably eat up all your RAM if you
try to operate on huge messages. In future versions, this will be
addressed by reading from and returning filehandles, rather than using
in-core data.

=item *

Methods may break if you don't use ASCII armoring.

   jrray\x40spacemeat.com for suggesting File::Temp).

Revision 1.30  2002/09/20 15:25:47  cvs

- Fixed up tempfile handling and eliminated calls to the shell in
   encrypt(), sign() and msginfo(). Passing all currently defined
   tests.

- Hopefully also fixed signing during encryption and verification of
   detached signatures. Not tested this yet.

Revision 1.29  2002/09/20 11:19:02  cvs

- Removed hack to Version: string. Only the Comment: string in GPG
   output is now modified by Crypt::GPG. (Thanks to
   eisen\x40schlund.de for pointing out the bug here)

- Removed code that incorrectly replaced 'PGP MESSAGE' with 'PGP
   SIGNATURE' on detached signatures. (Thanks to ddcc\x40mit.edu for
   pointing this out).

- Fixed up addkey() to properly handle pretend mode and to
   selectively import only requested key IDs from a key block.

- parsekeys() now also figures out which keyring a key belongs to.

- Added certify() method, to enable certifying keys.

- Added Crypt::GPG::Signature methods - validity(), keyid(), time()
   and trusted().
