What Is GUID or UUID?

GUID (Globally Unique Identifier) or UUID (Universally Unique Identifier) is a 128 bit number which used to identify information in computer systems. When we generate the GUID/UUID at any point of time, it's always going to be unique and there will not be any duplicate of this number.

What Are The Different Ways To Generate GUID?

There are several ways to generate the GUID as listed below.

  1. Random GUID: Using random number generator of the system to generate the 128 bit number.
  2. Time & MAC Address Based GUID: Using current system timestamp and the machine's MAC address to generate the 128 bit number.
  3. MD5 Hashing Based GUID: Using MD5 hashing algorithm to hash the namespace (URLs, fully qualified domain names and object identifiers) to generate the 128 bit number.
  4. SHA1 Hashing Based GUID: Using SHA1 hashing algorithm to hash the namespace (URLs, fully qualified domain names and object identifiers) to generate the 128 bit number.
