Generate A Pseudo GUID Using ASP

This example returns a random unique ID not formatted as a GUID. It does not rely on the Windows internal GUID generator which would be considered more likely to adhere the GUID defined guidelines. This function was obtained at freevbcode.com and there is no discussion or proof as to the randomness or potential number of unique identifiers.

What is a GUID? Excerpt from Wikipedia: "A globally unique identifier or GUID is a special type of identifier used in software applications to provide a reference number which is unique in any context (hence, "globally"), for example, in defining the internal reference for a type of access point in a software application, or for creating unique keys in a database. While each generated GUID is not guaranteed to be unique, the total number of unique keys (2128 or 3.4×1038) is so large that the probability of the same number being generated twice is extremely small."

GUIDs are useful in creating anti-CSRF tokens for web applications. Generate a True GUID Using ASP. Generate A GUID Using PHP.
