What are UUID/GUID strings?

A UUID (Universally Unique IDentifier), also called GUID (Globally Unique IDentifier), string represents a 128-bit number used to uniquely identify information in computer systems.

The UUID/GUID standard is defined in RFC 4122 and ISO/IEC 9834-8. It has 5 versions and several variations:

  • Version 5 - Generated by applying the SHA1 algorithm on a given namespace identifier.
  • Version 4 - Generated Randomly.
  • Version 3 - Generated by applying the MD5 algorithm on a given namespace identifier.
  • Version 2 - Generated by a given MAC address and modified current timestamp.
  • Version 1 - Generated by a given MAC address and current timestamp.

A UUID string has 32 hexadecimal digits and is usually displayed in 5 groups in an 8-4-4-4-12 digit pattern. The 13th hexadecimal digit is used to identify the UUID version. For example, "c56a4180-65aa-42ec-a945-5fd21dec0538" is a version 4 UUID.
