trid

Totally Random Identifiers

trid is a GUID library built for speed, size, and anonymity.

Cryptographically secure random GUIDs can be generated at extremely high speeds and very low memory usage:

GUIDs are 12 bytes in length raw, and 20 characters in length encoded as strings. Base32 encoding is used so that the non alphanumeric characters of base64 don't cause a problem.

trid was heavily inspired by xid, much of the code is taken from there. This repository was necessary for me as I do not want PIDs, timestamps, or machine identifiers in my GUIDs, and I don't care if my GUIDs are sortable.
