Error following README.md to create Addres on Erlang/OTP 24 / Elixir 1.14.3

[cdesch]

I get this error when following the README.md process of:

keypair = BSV.KeyPair.new()
address = BSV.Address.from_pubkey(keypair.pubkey)
BSV.Address.to_string(address)

Which then results in this error:

iex(1)> keypair = BSV.KeyPair.new()
%BSV.KeyPair{
  privkey: %BSV.PrivKey{
    d: <<158, 191, 224, 206, 21, 116, 27, 141, 115, 132, 31, 244, 71, 175, 64,

This is on Elixir and Erlang Version:

Erlang/OTP 24 [erts-12.2.1] [source] [64-bit] [smp:16:16] [ds:16:16:10] [async-threads:1] [jit]

Elixir 1.14.3 (compiled with Erlang/OTP 24)

[libitx]

A :notsup error comes from Erlang's crypto module when an algorithm isn't supported. In this case a pubkey is being hashed with :sha256 which causes the error.

This will be down to how Erlang is built on your machine. What OS are you working with and is OpenSSL installed on the machine?
