Base58 (Bitcoin alphabet)
Demo of the p/moul/x/daily/b58 library — base conversion from raw bytes (base-256) to base-58, using the Bitcoin alphabet (no 0, O, I, l), pure byte-slice math, no math/big.
Alphabet

Try it
Append a hex string to the path to encode/round-trip it:
/68656c6c6f— the bytes for "hello"/00000000— four zero bytes/deadbeef
