Python, SSL/TLS certificates and default validation

Posted on .

Back in September, I wrote about Python’s server certificate validation in smtplib regarding the Putmail project, and how I use msmtp nowadays for that reason instead of fixing my own software. This week, lwn.net gave public access to an article about Python’s certificate validation in httplib, urllib and urllib2. The background is the same, even if they don’t mention smtplib, and is worth reading if you’re a Python developer.
