UUID Decoder

EMERGENCY: RealityRipple Software is in need of assistance! Due to unexpected and major power problems, all project development and technical support is on hold indefinitely. Any donations would be incredibly appreciated at this time.

Did you know that RealityRipple Software is solar-powered software? Since 2003, RealityRipple Software has been run off-grid, relying on independently owned and operated solar panels, batteries, and a backup propane generator, while providing a negative carbon footprint by preserving over 200 acres of untouched forest.
Please consider making a donation to keep RealityRipple Software running!

A Universally Unique Identifier, commonly referred to as a UUID or GUID, is a method of generating a moderately sized, unique identification value. Commonly used in registration systems of various types, these identifiers actually have multiple standards and can even contain data, despite appearing random.
This tool supports all variants of Versions 0 through 5 of the UUID standard, as well as "Version 6" by Bradley Peabody. For details on these versions, see the ITEF RFC Whitepaper or the Wikipedia article.

Enter your UUID and press the button to decode.

When decoding version 3 or version 5 UUIDs, two unknown nibbles will be marked with question marks in the Hash data. The first nibble is always completely unknown, but only the first two bits of the second nibble are unknown. The second two bits of the second unknown nibble will be listed above as "Second Nibble".
When decoding version 2 UUIDs, the Generated date value may be off by up to seven minutes.
