base58 state

Alphabet

Alphabet is the Bitcoin Base58 alphabet.

Encode

Encode converts a byte slice to its Base58 string representation. Algorithm: treat the input as a big base-256 integer and repeatedly convert it into base-58 digits via a carry loop, most-significant digit first. Each leading zero byte becomes a leading '1'.

Decode

Decode converts a Base58 string back to the original byte slice. It returns nil if the string contains a character outside the alphabet. Algorithm: the mirror of Encode — treat the string as a big base-58 integer and convert it back to base-256 bytes with a carry loop. Each leading '1' becomes a leading zero byte.

IsValid

IsValid reports whether every character of s belongs to the Base58 alphabet.

Render

Render produces the gnoweb Markdown view. - "/" → the alphabet + a small gallery of worked examples. - "/\<hex>" → decode the hex input to bytes, show its Base58, and the hex-encoded decoded round-trip to prove Encode/Decode are inverse.
