What is the point of including the domain tied to the address? It just decreases the anonymity of what you've hashed, and actually does a disservice. There are corporate domains in there and the namespace of what to search for becomes a lot smaller.

In addition, my domain is my name. I saw many others in the file that this was the case for. It's not a big leap to compute my e-mail from 'jedsmith.org', and I'm sure it isn't for those guys either. You're leaking data with this view.

Here's a version that is far more anonymous (and easier, I think): http://undertow.jedsmith.org/gawker/

I like it.

OS X users, if you are paranoid about using online tools for the SHA-256 hashing, you can do this from the command line with sha256deep.

Via Homebrew it'd go like this (replace the 1st step with whatever package manager you like):

$ brew install md5deep

$ echo -n my@email | sha256deep

The hash is md5 not sha
