Generate fixed-length unique strings
807605Jul 30 2007 — edited Jul 30 2007Hi all,
I'm trying to generate 16 byte unique string from two input strings. Essentially, the unique string will be used as primary key in the database. The two input strings are (siteUrl, productId) in which siteUrl is the url of a website which has one or more productId. Each productId in a site is unique but there might be duplicate productIds from different sites. I want to generate 16 byte ids from each pair of (siteUrl, productId) such that they are unique (or have a very small chance of collision). Has anyone done this before? Please share your experience! Thanks heap!
