A Base58 Encoder converts binary data into a text representation using 58 alphanumeric characters, specifically designed to avoid visually similar ones like '0', 'O', 'I', and 'l'. This encoding is commonly used in cryptocurrencies, such as Bitcoin, to generate user-friendly addresses. By eliminating ambiguous characters, Base58 reduces the risk of transcription errors during manual data entry. Additionally, it omits non-alphanumeric characters, facilitating easier copying and pasting of the encoded data.

A Base58 Decoder reverses this process, transforming Base58-encoded text back into its original binary form. It interprets each character of the encoded string, maps it back to its corresponding value, and reconstructs the original data. This decoding is essential for applications like retrieving the original binary data from a Bitcoin address or other Base58-encoded information. The design of Base58 ensures that decoded data is free from errors caused by misinterpretation of similar-looking characters.
