Certificates
------------
Certificates in general are part of a public-key / private-key system. In this system, each *principal*,
(which may be a machine, or a person, or an organization) is assigned a unique two-part encryption key.
One part of the key is public, and is called the *public key*; the other part is kept secret, and is called
the *private key*. The two parts are related, in that if you encrypt a message with one of the parts, you can
decrypt it with the other part, and **only** with the other part.

message with one of the parts, you can decrypt it with the other part, and
**only** with the other part.
A certificate contains information about two principals. It contains
the name of a *subject*, and the subject's public key. It also
contains a statement by a second principal, the *issuer*, that the
subject is who he claims to be, and that this is indeed the subject's
public key. The issuer's statement is signed with the issuer's
private key, which only the issuer knows. However, anyone can verify
the issuer's statement by finding the issuer's public key, decrypting
the statement with it, and comparing it to the other information in
the certificate. The certificate also contains information about the
time period over which it is valid. This is expressed as two fields,
called "notBefore" and "notAfter".

In the Python use of certificates, a client or server
can use a certificate to prove who they are. The other
side of a network connection can also be required to produce a certificate,
and that certificate can be validated to the satisfaction
of the client or server that requires such validation.
The connection attempt can be set to raise an exception if
the validation fails. Validation is done
automatically, by the underlying OpenSSL framework; the
application need not concern itself with its mechanics.
But the application does usually need to provide
sets of certificates to allow this process to take place.

The Python files which contain certificates can contain a sequence
of certificates, sometimes called a *certificate chain*. This chain
should start with the specific certificate for the principal who "is"
the client or server, and then the certificate for the issuer of that
certificate, and then the certificate for the issuer of *that* certificate,
and so on up the chain till you get to a certificate which is *self-signed*,
that is, a certificate which has the same subject and issuer,
sometimes called a *root certificate*. The certificates should just
be concatenated together in the certificate file. For example, suppose
we had a three certificate chain, from our server certificate to the
certificate of the certification authority that signed our server certificate,
