## What it is
A small C++ library for base64 encoding and decoding. It provides simple functions to convert data to and from base64 representation.

## Use cases
- encode binary data as base64 in c++
- decode base64 strings in c++
- embed base64 encoding in a c++ project
- convert images or files to base64 for embedding
- base64 encode data for email or http headers

## When to choose
- you need a lightweight, dependency-free base64 implementation in c++
- you want a simple, well-known single-purpose library
- you need to encode or decode base64 without pulling in a large framework

## When to avoid
- your project already uses a large library like OpenSSL or Boost that includes base64 utilities
- you need streaming or high-performance bulk encoding of very large data
- you require a permissively licensed library, as the license is non-standard

## Facets
- artifact type: library
- maturity: stable
- function: serialization
- domain: developer-tools, files
- platform: cpp, cross-platform
- tags: base64, encoding, decoding, header-only
