Frequently Asked Questions

Why use a "0x" prefix?

The "0x" prefix is a common convention to indicate that a number is in hexadecimal format. It helps to avoid ambiguity, especially when dealing with mixed number systems.

How are separators handled?

The separator is inserted *between* the hexadecimal representations of the decoded *bytes*.

Is my data secure?

All processing is done client-side in your browser. No data is sent to a server.

What is Base58?

Base58 is a group of binary-to-text encoding schemes used to represent large integers as alphanumeric text. It is similar to Base64 but omits characters that are easily mistaken for each other (e.g., 0, O, I, l). It's commonly used in cryptocurrencies like Bitcoin.

Why are leading 1s in Base58 important?

In Base58, leading '1' characters have a special meaning. They represent leading zero bytes in the original data. This converter correctly handles these leading '1's by adding leading '00's to the hexadecimal output.

Technical Details

Hexadecimal Representation

Each byte (8 bits) of the decoded data is represented by two hexadecimal digits (0-9 and A-F).

Conversion Process

The Base58 input is first decoded by converting it to its numerical representation and converting that number to base 16 (hexadecimal). Leading '1' are taking care of by padding the hexadecimal result.
