This module provides some more Pythonic support for SSL.
Object types:
sslsocket -- subtype of socket.socket which does SSL over the socket
Exceptions:
sslerror -- exception raised for I/O errors
Functions:
cert_time_to_seconds -- convert time string used for certificate
notBefore and notAfter functions to integer
seconds past the Epoch (the time values
returned from time.time())
fetch_server_certificate (HOST, PORT) -- fetch the certificate provided
by the server running on HOST at port PORT. No
validation of the certificate is performed.
Integer constants:
SSL_ERROR_ZERO_RETURN
SSL_ERROR_WANT_READ
SSL_ERROR_WANT_WRITE
SSL_ERROR_WANT_X509_LOOKUP
SSL_ERROR_SYSCALL
SSL_ERROR_SSL
SSL_ERROR_WANT_CONNECT
SSL_ERROR_EOF
SSL_ERROR_INVALID_ERROR_CODE
The following group define certificate requirements that one side is
allowing/requiring from the other side:
CERT_NONE - no certificates from the other side are required (or will
be looked at if provided)
CERT_OPTIONAL - certificates are not required, but if provided will be
validated, and if validation fails, the connection will
also fail
CERT_REQUIRED - certificates are required, and will be validated, and
if validation fails, the connection will also fail
The following constants identify various SSL protocol variants:
PROTOCOL_SSLv2
PROTOCOL_SSLv3
PROTOCOL_SSLv23
PROTOCOL_TLSv1

# Root certs:
#
# The "ca_certs" argument to sslsocket() expects a file containing one or more
# certificates that are roots of various certificate signing chains. This file
# contains the certificates in PEM format (RFC ) where each certificate is
# encoded in base64 encoding and surrounded with a header and footer:
# -----BEGIN CERTIFICATE-----
# ... (CA certificate in base64 encoding) ...
# -----END CERTIFICATE-----
# The various certificates in the file are just concatenated together:
# -----BEGIN CERTIFICATE-----
# ... (CA certificate in base64 encoding) ...
# -----END CERTIFICATE-----
# -----BEGIN CERTIFICATE-----
# ... (a second CA certificate in base64 encoding) ...
# -----END CERTIFICATE-----
#
# Some "standard" root certificates are available at
#
# http://www.thawte.com/roots/ (for Thawte roots)
