Easy Portable UUID-GUID Generator — Fast, Secure Unique IDs

Easy Portable UUID-GUID Generator — Fast, Secure Unique IDs

Overview:
A lightweight, standalone tool for generating universally unique identifiers (UUIDs) and globally unique identifiers (GUIDs) without installation. Designed for portability across Windows, macOS, and Linux (standalone binary or single executable).

Key features:

• Fast generation: Produces UUIDs/GUIDs instantly, supporting high-throughput needs (single or bulk).
• Secure randomness: Uses cryptographically secure random number generators (CSPRNG) where available (e.g., OS entropy sources).
• Multiple versions supported: v1 (time-based), v3/v5 (namespace + name, MD5/SHA-1 or SHA-256 if extended), v4 (random), and optional UUIDv7-like time-ordered IDs.
• Export options: Copy to clipboard, save to plain text or CSV, or output to stdout for piping.
• Batch mode: Generate thousands or millions with configurable prefixes/suffixes, separators, and line formats.
• Command-line and GUI: Minimal GUI for quick use; full CLI for scripting and automation.
• No dependencies: Single-file executable or portable ZIP; no installer or system changes.
• Offline operation: Works entirely offline; no network required.
• Cross-platform parity: Identical behavior and options across supported OSes.
• Localization: Unicode support and simple translations for common languages.

Typical use cases:

• Generating IDs for databases, logs, or distributed systems.
• Creating unique filenames, test data, or license keys.
• Scripting bulk ID creation for imports or migrations.
• On-the-go use from USB drives or constrained environments.

Security & privacy:
Generates IDs locally using system entropy; no data is sent externally. Suitable for contexts where offline generation is required.

Example CLI usage:

bash
Copy CodeCopied
# generate a single random v4 UUID
uuidgen-portable –version 4

# generate 1000 v4 UUIDs, output to file
uuidgen-portable –version 4 –count 1000 –output ids.csv 
# generate v1 IDs and print to stdout
uuidgen-portable –version 1 –format plain 

Minimal system requirements:

• 10 MB disk space for binary + config, optional GUI dependencies included where applicable.
• Modern x86_64 or ARM64 CPU; Windows/macOS/Linux support.

Distribution & license:
Commonly distributed as a permissively licensed open-source project (MIT/Apache), or as a small proprietary utility; packaged as ZIP, Homebrew/snap, and single-file installers where permitted.

Alternatives:

• Built-in OS utilities (e.g., uuidgen) for simple needs.
• Programming libraries (UUID packages in Python, Node.js, Go) for integration into applications.
