Python Own Certificate Authority (OwnCA)

OwnCA makes it easy to handle a Certificate Authority (CA) and manage certificates for hosts, servers or clients.

An example of high-level usage:

>>> from ownca import CertificateAuthority
>>> ca = CertificateAuthority(ca_storage='/opt/CA', common_name='Corp CA')
>>> example_com = ca.issue_certificate('www.example.com', dns_names=['www.example.com', 'w3.example.com'])

Basically, in these three lines we:

1. Imported the ownca Certificate Authority library

2. Created a new CA named Corp CA that uses /opt/CA as CA storage for certificates, keys, etc.

3. Created a signed certificate by Corp CA for www.example.com, whose files are also stored in /opt/CA/certs/www.example.com

    >>> example_com.cert
    <Certificate(subject=<Name(CN=www.example.com)>, ...)>
   

More detailed usage can be found in http://ownca.readthedocs.org.
