Create unique integer from an alpha-numeric string

I am seeding a database in Rails. The seed data contain ID's, and I need to set those ID's as my primary keys. The primary keys in the seeded data are alpha-numeric. Rails needs its primary keys to be integers. I am thinking there has to be some way to convert an alpha-numeric string to a unique integer. It can't be random. Something equivalent to the decoder ring in your cracker jacks.

If you do not need to distinguish upper and lower cases, then for example,

"fkfj23".to_i(36) # => 941309499
