What is UUID?
A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify data. It consists of five groups of characters separated by hyphens, such as:
For example:
- 550e8400-e29b-41d4-a716-446655440000
UUIDs are created using random numbers or based on time and machine identifiers. This ensures that each UUID is globally unique.
Types of UUIDs
UUIDs come in different versions, each serving a different purpose:
- UUID v1 – Generated based on time, date, and machine address. Ensures uniqueness but may reveal system details.
- UUID v4 – Created randomly, making it the most secure and widely used.
- UUID v3 & v5 – Generated using a hash function and a namespace, useful for consistent UUIDs based on input data.
Most users prefer UUID v4 because it offers complete randomness and better privacy.
