UUID Generator

Generate universally unique identifiers (UUIDs) in various formats for distributed systems, databases, and APIs.

Purpose

UUID generation for:

• Database primary keys
• API resource identifiers
• Distributed system coordination
• Session tokens and tracking
• File naming and versioning

Features

• Multiple Versions: UUID1 (time-based), UUID4 (random), UUID5 (namespace)
• Bulk Generation: Generate thousands of UUIDs
• Custom Formats: Hyphenated, compact, URN format
• Namespace UUIDs: Deterministic UUIDs from names
• Validation: Check UUID format and version
• Export: CSV, JSON, plain text

Quick Start

from uuid_generator import UUIDGenerator

# Generate UUID4 (random)
gen = UUIDGenerator()
uuid = gen.generate()  # 'a1b2c3d4-e5f6-4789-g0h1-i2j3k4l5m6n7'

# Bulk generation
uuids = gen.generate_bulk(count=1000, version=4)

# Namespace UUID (deterministic)
uuid = gen.generate_namespace('example.com', namespace='dns')

CLI Usage

# Generate single UUID
python uuid_generator.py

# Generate 1000 UUIDs
python uuid_generator.py --count 1000 --output uuids.txt

# Generate namespace UUID
python uuid_generator.py --namespace dns --name example.com
