I've been doing this kind of thing for years with two notable differences:
1. I don't believe people actually hand type-in these values, so I'm not really concerned about the 'l' vs '1' issue. I do base 32 without `eiou` (vowels) to reduce the likelihood of words (profanity) sneaking in.
2. I add two base-32 characters as a checksum (salted of course). This is prevents having to go look at the datastore when the value is bogus either by accident or malice. I'm unsure why other implementations don't do this.
