Hi everyone,
I like to know how to how to implement the following Ruby code in Elixir. I guess that I need to look in the Erlang crypto reference but I can’t figure out how to translate the code to Elixir/Erlang.
group = OpenSSL::PKey::EC::Group.new("prime256v1")
key = OpenSSL::PKey::EC.new(group)
pk_bn = OpenSSL::BN.new(pk_bytes, 2)
pk = OpenSSL::PKey::EC::Point.new(group, pk_bn)
I already found how to generate the key.
:crypto.generate_key(:ecdh, :prime256v1)
But how to create the public key bignum (pk_bn) and the public key (pk)?
ps the pk_bytes variable is passed in as a parameter.

So if I understand correctly,
pk_bytesis a raw ECC public key without a curve identity, just a point. The curve is hardcoded toprime256v1.In that case you should be able to verify a signature like this:

It took a while before I finally was able to test this but it works like a charm. Thanks Voltone!

Sorry I don’t know exactly what that Ruby code is doing, but probably the app you are looking for is
