WSGI OpenPGP public key submission system

pgpsubmit is a simple WSGI application that can be used for collecting OpenPGP public keys on a keyring e.g. for a keysigning party.

Features include:

• submission deadline and "time remaining" display
• keyring and key list export (with MD5 and SHA-1 hashes)
• configured entirely through environment

Dependencies

• GnuPG
• A WSGI capable web server (e.g. Apache with mod_wsgi).

Configuration

Three WSGI environ variables must be set:

PGPSUBMITEXECUTABLE

Name or full path of the GnuPG executable. If the value does not begin with "/", an executable will be looked for on PATH by the normal mechanism. If using Apache httpd and encountering OSError, try specifying the full path to the GnuPG executable.

GNUPGHOME

The GnuPG home directory. Must be writable by the user running the application. Multiple pgpsubmit instances could be run in parallel, each with a different GNUPGHOME.

PGPSUBMITSOURCEURL

URL at which may be found the corresponding source of pgpsubmit, pursuant to section 15 of the AGPL. If you run a modified version of pgpsubmit, the source code for that modified version must be available at this URL.

There are some other configuration variables for controlling submission deadlines:

PGPSUBMITUNTIL

Specify a deadline for submission. After this time, submission will be disabled, and a message to effect of same will appear. While the deadline looms, time remaining will be displayed. The format is 'Y.M.D[.H[.M[.S]]]'.

PGPSUBMITDOWNLOADEARLY

If a deadline is set, links to download the keyring and key list are not shown until the submission deadline is reached. Settings this environment variable (to any value) causes these links to be shown regardless of whether or not the deadline has passed.

A configuration for Apache with mod_wsgi might be:

<Directory /usr/home/joe/pgpsubmit>
    Order allow,deny
    Allow from all
</Directory>

<VirtualHost *:80>
    ServerAdmin joe@example.com
    ServerName pgpsubmit.example.com
    DocumentRoot "/usr/home/joe/pgpsubmit"

    WSGIScriptAlias / /usr/home/joe/pgpsubmit/scripts/pgpsubmit.wsgi
    SetEnv PGPSUBMITEXECUTABLE /usr/local/bin/gpg
    SetEnv GNUPGHOME /usr/home/joe/.pgpsubmit
    SetEnv PGPSUBMITSOURCEURL https://github.com/frasertweedale/pgpsubmit
    SetEnv PGPSUBMITUNTIL 2011.12.31.18.30
</VirtualHost>
