bits. (Default: 4096)</li>
<li><strong>key_grip</strong> (<a class="reference external" href="http://docs.python.org/library/functions.html#str" title="(in Python v2.7)"><em>str</em></a>) &#8211; hexstring This is an optional hexidecimal string
which is used to generate a CSR or certificate for an already
existing key. <tt class="docutils literal"><span class="pre">key_length</span></tt> will be ignored if this parameter
is given.</li>
<li><strong>key_usage</strong> (<a class="reference external" href="http://docs.python.org/library/functions.html#str" title="(in Python v2.7)"><em>str</em></a>) &#8211; Space or comma delimited string of key
usages. Allowed values are ‘encrypt’, ‘sign’, and ‘auth’. This is
used to generate the key flags. Please make sure that the
algorithm is capable of this usage. Note that OpenPGP requires
that all primary keys are capable of certification, so no matter
what usage is given here, the ‘cert’ flag will be on. If no
‘Key-Usage’ is specified and the ‘Key-Type’ is not ‘default’, all
allowed usages for that particular algorithm are used; if it is
not given but ‘default’ is used the usage will be ‘sign’.</li>
<li><strong>subkey_type</strong> (<a class="reference external" href="http://docs.python.org/library/functions.html#str" title="(in Python v2.7)"><em>str</em></a>) &#8211; This generates a secondary key
(subkey). Currently only one subkey can be handled. See also
<tt class="docutils literal"><span class="pre">key_type</span></tt> above.</li>
<li><strong>subkey_length</strong> (<a class="reference external" href="http://docs.python.org/library/functions.html#int" title="(in Python v2.7)"><em>int</em></a>) &#8211; The length of the secondary subkey in bits.</li>
<li><strong>subkey_usage</strong> (<a class="reference external" href="http://docs.python.org/library/functions.html#str" title="(in Python v2.7)"><em>str</em></a>) &#8211; Key usage for a subkey; similar to
<tt class="docutils literal"><span class="pre">key_usage</span></tt>.</li>

&lt;int&gt;[d|w|m|y] Set the expiration date for the key (and the
subkey). It may either be entered in ISO date format (2000-08-15)
or as number of days, weeks, month or years. The special notation
&#8220;seconds=N&#8221; is also allowed to directly give an Epoch
value. Without a letter days are assumed. Note that there is no
check done on the overflow of the type used by OpenPGP for
timestamps. Thus you better make sure that the given value make
sense. Although OpenPGP works with time intervals, GnuPG uses an
absolute value internally and thus the last year we can represent
is 2105.</li>
<li><strong>creation_date</strong> (<a class="reference external" href="http://docs.python.org/library/functions.html#str" title="(in Python v2.7)"><em>str</em></a>) &#8211; Set the creation date of the key as stored
in the key information and which is also part of the fingerprint
calculation. Either a date like &#8220;1986-04-26&#8221; or a full timestamp
like &#8220;19860426T042640&#8221; may be used. The time is considered to be
UTC. If it is not given the current time is used.</li>
<li><strong>passphrase</strong> (<a class="reference external" href="http://docs.python.org/library/functions.html#str" title="(in Python v2.7)"><em>str</em></a>) &#8211; The passphrase for the new key. The default is
to not use any passphrase. Note that GnuPG&gt;=2.1.x will not allow
you to specify a passphrase for batch key generation &#8211; GnuPG will
ignore the <strong>passphrase</strong> parameter, stop, and ask the user for
the new passphrase.  However, we can put the command
<tt class="docutils literal"><span class="pre">%no-protection</span></tt> into the batch key generation file to allow a
passwordless key to be created, which can then have its passphrase
set later with <tt class="docutils literal"><span class="pre">--edit-key</span></tt>.</li>
<li><strong>preferences</strong> (<a class="reference external" href="http://docs.python.org/library/functions.html#str" title="(in Python v2.7)"><em>str</em></a>) &#8211; Set the cipher, hash, and compression
preference values for this key. This expects the same type of
string as the sub-command ‘setpref’ in the &#8211;edit-key menu.</li>
<li><strong>revoker</strong> (<a class="reference external" href="http://docs.python.org/library/functions.html#str" title="(in Python v2.7)"><em>str</em></a>) &#8211; Should be given as &#8216;algo:fpr&#8217; (case sensitive).
Add a designated revoker to the generated key. Algo is the public
key algorithm of the designated revoker (i.e. RSA=1, DSA=17, etc.)
fpr is the fingerprint of the designated revoker. The optional
‘sensitive’ flag marks the designated revoker as sensitive
information. Only v4 keys may be designated revokers.</li>
<li><strong>keyserver</strong> (<a class="reference external" href="http://docs.python.org/library/functions.html#str" title="(in Python v2.7)"><em>str</em></a>) &#8211; This is an optional parameter that specifies the
preferred keyserver URL for the key.</li>
<li><strong>handle</strong> (<a class="reference external" href="http://docs.python.org/library/functions.html#str" title="(in Python v2.7)"><em>str</em></a>) &#8211; This is an optional parameter only used with the
status lines <tt class="docutils literal"><span class="pre">KEY_CREATED</span></tt> and <tt class="docutils literal"><span class="pre">KEY_NOT_CREATED</span></tt>. string may
be up to 100 characters and should not contain spaces. It is
useful for batch key generation to associate a key parameter block
with a status line.</li>

<p>Note that this method is not for signing other keys. (In GnuPG&#8217;s
terms, what we all usually call &#8216;keysigning&#8217; is actually termed
&#8216;certification&#8217;...) Even though they are cryptographically the same

meaning that the secret portion of the keypair, also used for
decryption in this scenario, would have a statistically higher

portion of the rounds in the cipher algorithm, depending on the family
of cryptanalytic attack used).</p>

<p>Parser for status messages from GnuPG for certifications and signature
verifications.</p>
<p>People often mix these up, or think that they are the same thing. While it
is true that certifications and signatures <em>are</em> the same cryptographic
operation &#8211; and also true that both are the same as the decryption
operation &#8211; a distinction is made for important reasons.</p>
<dl class="docutils">
<dt>A certification:</dt>
<dd><ul class="first last simple">
<li>is made on a key,</li>
<li>can help to validate or invalidate the key owner&#8217;s identity,</li>
<li>can assign trust levels to the key (or to uids and/or subkeys that
the key contains),</li>
<li>and can be used in absense of in-person fingerprint checking to try
to build a path (through keys whose fingerprints have been checked)
to the key, so that the identity of the key&#8217;s owner can be more
reliable without having to actually physically meet in person.</li>
</ul>
</dd>
<dt>A signature:</dt>
<dd><ul class="first last simple">
<li>is created for a file or other piece of data,</li>
<li>can help to prove that the data hasn&#8217;t been altered,</li>
<li>and can help to prove that the data was sent by the person(s) in
possession of the private key that created the signature, and for
parsing portions of status messages from decryption operations.</li>
</ul>
</dd>
</dl>
<p>There are probably other things unique to each that have been
scatterbrainedly omitted due to the programmer sitting still and staring
at GnuPG debugging logs for too long without snacks, but that is the gist
of it.</p>
<p>Create a parser for verification and certification commands.</p>

<h2>About this fork<a class="headerlink" href="#about-this-fork" title="Permalink to this headline">¶</a></h2>
<p>This is a modified version of <a class="reference external" href="https://code.google.com/p/python-gnupg/">python-gnupg</a>, (forked from version 0.3.2) which
was created by Vinay Sajip, which itself is a modification of GPG.py written
by Steve Traugott, which in turn is a modification of the pycrypto GnuPG
interface written by A.M. Kuchling.</p>
<p>This version is patched to sanitize untrusted inputs, due to the necessity of
executing <tt class="docutils literal"><span class="pre">subprocess.Popen([...],</span> <span class="pre">shell=True)</span></tt> in order to communicate with
GnuPG. Several speed improvements were also made based on code profiling, and
the API has been cleaned up to support an easier, more Pythonic, interaction.</p>
