A Lua module for converting strings to base58. It works by converting your string into an interal big integer representation, then diving out the base58 components.

local base58 = require("base58")
print(base58.encode_base58("Hello world"))
print(base58.decode_base58("TvjnTzXAiTprExJ"))

luarocks install base58

All functions are available in the base58 module:

local base58 = require("base58")

The following alphabet is included and used by default. It's currently not possible to configure the alphabet without editing the source.
