base58check

Base58Check is an Elixir library that provides Base58Check encoding and decoding functionality, specifically tailored for Bitcoin applications. It implements the encoding scheme used in Bitcoin addresses and private keys, offering a reliable way to handle cryptographic data representation.

Key Features

• Bitcoin Alphabet Support — Uses the Bitcoin-specific Base58 alphabet (excluding ambiguous characters like 0, O, I, l)
• Four Core Functions — Provides encode58/1, decode58/1, encode58check/2, and decode58check/1 for comprehensive encoding/decoding operations
• Multiple Input Types — encode58check/2 accepts hex strings, binaries, or integers for flexible data handling
• Structured Output — decode58check/1 returns a tuple with prefix and payload for easy data extraction

Philosophy

The library follows a minimal, focused approach to implementing the Base58Check specification exactly as defined in the Bitcoin ecosystem, prioritizing correctness and interoperability over unnecessary features.
