The encode endpoint turns text (UTF-8) or raw hex bytes into a Base45 string; the decode endpoint turns a Base45 string back into bytes, returned as hex and, when the bytes are valid UTF-8, as text. It uses the 45-character alphabet (0-9, A-Z and a few symbols) and validates length and value ranges strictly. Pure local, no key."
