Yes! I've been using this method for years. But, similar to the article's premise, I actually have four different hash functions, of increasing complexity. Then, all I have to remember is what's the URL, what's its general level of data security, and what's the hash function for that level of security. The simplest hash is trivial to apply and can be done in real-time, but the most complex hash actually requires me to spend a minute or so to calculate.
