XUID

XUID is an ID that contains the exact same number of bits as a UUID, adds a type prefix, and is encoded in a string that will not be larger than 36 characters.

This is achieved by using base32 instead of base16. Base32 still only uses one set of alphabetic characters, allowing caseless matches.

Type

The type is a up to 5 characters long code that specifies what kind of object the ID is of. It is used to allow easy identification of an ID, either by humans or automated code.

Examples

• UUID 3f1b4d37-34d9-46c6-b546-a57c5f736d22 with type shell becomes shell-h4nu2n-zu3f-dmnn-kguv-6f643nei
• UUID 00000000-0000-0000-0000-000000000000 with type null becomes null-aaaaaa-aaaa-aaaa-aaaa-aaaaaaaa
