Both encode/1 and decode/1 functions are of (binary()) -> binary() type.

The usage looks like:

B = crypto:rand_bytes(10).
H = base16:encode(B).
B = base16:decode(H).

Please, note:

• base16:encode/1 uses upper-case latters.
• base16:decode/1 requires the argument to be a binary of odd-number size.
