## Discourse Security

We take security very seriously at Discourse. We welcome any peer review of our 100% open source code to ensure nobody's Discourse forum is ever compromised or hacked.

### Where should I report security issues?

In order to give the community time to respond and upgrade we strongly urge you report all security issues privately. Please email us at `team@discourse.org` with details and we will respond ASAP. Security issues *always* take precedence over bug fixes and feature work. We can and do mark releases as "urgent" if they contain serious security fixes.

### Password Storage

Discourse uses the PBKDF2 algorithm to encrypt salted passwords. This algorithm is blessed by NIST. Security experts on the web [tend to agree that PBKDF2 is a secure choice](http://security.stackexchange.com/questions/4781/do-any-security-experts-recommend-bcrypt-for-password-storage).

**options you can customise in your production.rb file**

- `pbkdf2_algorithm`: the hashing algorithm used (default "sha256")
- `pbkdf2_iterations`: the number of iterations to run (default 64000)

### XSS

The main vector for [XSS](https://en.wikipedia.org/wiki/Cross-site_scripting) attacks is via the post composer, as we allow users to enter Markdown, HTML (a safe subset thereof), and BBCode to format posts.
