## Overview

The Base32 Converter is a versatile utility designed to encode plain text into Base32 format or decode existing Base32 strings back into readable text. It supports multiple industry-standard variants, including RFC 4648, Crockford, and Extended Hex, ensuring compatibility across various technical systems and data transmission requirements.

## Inputs

- **Input Text** (textarea): Enter text to encode or Base32 text to decode...
- **Operation** (select)
- **Base32 Variant** (select)

## When to use

- When you need to represent binary data as human-readable text for storage or transmission.
- When troubleshooting or verifying data encoded in specific Base32 variants like Crockford or RFC 4648.
- When migrating legacy systems that rely on Base32 encoding for identifiers or configuration strings.

## How it works

- Enter your source text or Base32 string into the input field.
- Select the desired operation: 'Encode to Base32' or 'Decode from Base32'.
- Choose the appropriate Base32 variant (RFC 4648, Crockford, or Hex) to match your specific data requirements.
- Click the convert button to instantly generate and display your transformed output.

## Use cases

- Encoding short configuration strings for URL-safe transmission.
- Decoding Base32-encoded identifiers from legacy system logs.
- Generating human-readable checksums or tokens using the Crockford variant.

## Frequently asked questions

### What is the difference between RFC 4648 and Crockford Base32?

RFC 4648 is the standard implementation using A-Z and 2-7. Crockford is an optimized variant designed to be human-readable by excluding ambiguous characters like I, L, O, and U.

### Can I use this tool to encode binary files?

This tool is designed for text-based input. For binary files, please convert the file content to a text string before processing.

### Why does my decoded output look like gibberish?

This usually happens if the wrong Base32 variant is selected. Ensure the variant used for decoding matches the one used during the original encoding process.

### Is my data stored on your servers?

No, all encoding and decoding operations are performed locally in your browser for your privacy and security.

### What is the 'Hex' variant used for?

The Extended Hex variant uses 0-9 and A-V, which preserves the sort order of the encoded data, making it useful for database indexing.
