What encoding or data type can be used to get alphanumeric string in elixir?

My goal is to guess alphanumeric strings for Bitcoin mining to match leading zeros. For this, I have to increment the encoded string and check whether the string produces the expected Nonce.

For example in scala, we can use base36 binary to text encoding:- BigInt(someAlphaNumString, 36) and increment it by adding BigInt(1, 36) to our string.

What is the better way to do same in elixir?

Integers in Elixir are arbitrary precision integers, so there's no need for any special BigInt data type. You can convert a base-36 string to and from integer using String.to_integer/2 and Integer.to_string/2 like this:

iex(1)> a = String.to_integer("DOGBERT", 36)
29776764809
iex(2)> b = a + 1
29776764810
iex(3)> Integer.to_string(b, 36)
"DOGBERU"
