How do you convert a binary string to a Hexadecimal String and vice-versa in Elixir?
There are a few posts on SO regarding this topic for other "main stream" languages. There's even an SO post that benchmarks various C# implementations
How do we do this in elixir?
My implementation was too ugly to share... :(

There is Base.encode16/2:
iex(1)> Base.encode16("foo")
"666F6F"
You can also specify the case:
iex(2)> Base.encode16("foo", case: :lower)
"666f6f"
