Base32 Random ID Generator

About

Base32 encoding uses 32 characters (A-Z, 2-7) to represent binary data. Base32 IDs are case-insensitive, human-readable, and avoid ambiguous characters like 0, O, 1, I, and L. They're useful for identifiers that need to be communicated verbally or in case-insensitive contexts. Base32 is defined in RFC 4648 and is commonly used in applications like TOTP (Time-based One-Time Passwords) and various encoding schemes.

Use Cases

• •Case-insensitive identifier systems
• •Verbal communication of IDs
• •TOTP and two-factor authentication codes
• •Human-readable unique identifiers
• •Systems avoiding ambiguous characters
• •URL-safe identifiers (no special characters)

How to Generate

// Native implementation
const base32Chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ234567';
const bytes = new Uint8Array(10);
crypto.getRandomValues(bytes);
// Encode bytes to Base32...
