I’m actually pleased as punch to hear you make that contention, Nathan. I love Haml, and as it gets faster I only love it more.

I want to contend the claim that Erubis is much faster than Haml. According to my latest benchmarks (Haml 2.2.16 vs. Erubis 2.6.5, using the Haml benchmark), Haml is about 7.6% slower than Erubis, using the :ugly option which is enabled by default in production. This will of course fluctuate somewhat depending on the code, but it should never reach the level of “much slower.”

Comment on When you have to store user passwords… by Chris

Absolutely. As I noted in the article, that won’t protect you against a shell access compromise. Nothing can, really – if an attacker can get the same access to your code that your app can, he can get access to your key files or passphrases, unless you use a system where they’re loaded into application memory and then removed from the filesystem (something like a USB key, for example). At that point, they’ll have to resort to gdb, which is a somewhat tougher nut. ;)

It will, however, protect you from simple SQL injection attacks resulting in the attacker gaining all of your customers’ plaintext passwords. It’s not a perfect solution by any means, but it is a first line of defense.

Comment on When you have to store user passwords… by Prefect

It appears you are using AES encryption of the passwords, which would work well if all someone had was the output, for example the output of a database table of user credentials.

Except in the rockyou.com case, the actor had shell access (read access to the code the application used, along with that key equals value).

Does it also work with Nokogiri as XmlMini.backend? I have a xml builder that contains cdata sections and when converted to json or yaml the content wrapped within cdata is returned as '#cdata_section'. JSON:


{"items": {"item": [{"title": {"#cdata_section": null}, "id": "2", "description": {"#cdata_section": null}}, {"title": {"#cdata_section": null}, "id": "4", "description": {"#cdata_section": null}}]}}

YAML:


--- 
items: 
  item: 
  - title: 
      "#cdata_section": 
    id: "2"
    description: 
      "#cdata_section": 
  - title: 
      "#cdata_section": 
    id: "4"
    description: 
      "#cdata_section":
