UUID V4 Generator

Bulk UUID V4 Generation

What is a UUID?

A UUID, or Universally Unique Identifier, is a 128-bit number used to uniquely identify information in computer systems. UUIDs are essential in various applications, including databases, distributed systems, and software development, where unique identification is crucial. The version 4 UUID (UUID v4) is randomly generated, ensuring that the likelihood of duplication is incredibly low. This makes UUID v4 an excellent choice for generating unique identifiers for users, sessions, transactions, and more.

What is UUID v4?

UUID v4 is a specific version of the Universally Unique Identifier that is generated using random numbers. The UUID standard defines several versions, each with its own method of generation. UUID v4 stands out because it relies entirely on randomness, making it one of the most popular choices for generating unique identifiers.

Characteristics of UUID v4:

  1. Randomness: UUID v4 is generated using random or pseudo-random numbers. This randomness is crucial for ensuring uniqueness, as it minimizes the chances of generating the same identifier more than once.

  2. Format: A UUID v4 is represented as a 36-character string, typically displayed in five groups separated by hyphens. The format looks like this: xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx, where x is any hexadecimal digit and y is one of the characters from the set [8, 9, A, B].

  3. Size: UUIDs are 128 bits long, which translates to 32 hexadecimal characters. This length provides an astronomically high number of possible combinations (2^122), making collisions extremely unlikely.

  4. Use Cases: UUID v4 is widely used in various applications, including database keys, session identifiers, and unique filenames. Its random nature ensures that identifiers remain unique across different systems and environments.
