How Base58 Encoding Works
Base58 uses 58 characters: 123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz (excludes 0, O, I, l).
Input bytes are treated as a large number and converted to base-58 representation.
Leading zero bytes are preserved as '1' characters in the output.
Decoding reverses the process, converting base-58 digits back to bytes.
Bitcoin uses Base58Check which adds a checksum for error detection.
Frequently Asked Questions
Q.What is Base58 encoding?
A. Base58 is a binary-to-text encoding scheme used primarily in Bitcoin and cryptocurrencies. It excludes similar-looking characters (0, O, I, l) to avoid confusion when manually transcribing addresses.
Q.How is Base58 different from Base64?
A. Base58 uses 58 characters (excluding 0, O, I, l) instead of 64, making it more human-friendly for manual entry. It's commonly used for cryptocurrency addresses.
Q.Can I decode Bitcoin addresses?
A. Yes, Bitcoin addresses use Base58Check encoding. This tool can decode the Base58 portion, though checksum validation requires additional processing.
Q.Is my data secure?
A. Yes—all encoding and decoding happens locally in your browser. No data is sent to any server.
