Convert C# function to Elixir
this is the function that I am trying to convert to Elixir:
private static byte[] HashBody(string content)
{
var contentBytes = Encoding.UTF8.GetBytes(content);
using (var provider = new SHA256Managed())
{
var hash = provider.ComputeHash(contentBytes);
return hash;
}
}
My attempt:
content = %{
"id" => "123",
"name" => "Jaqob"
} |> Poison.encode!
digest = :crypto.hash(:sha256, content)
I want to convert content variable to bytes which is where I am stuck, also is the hashing function correct?

BTW, just FYI and FWIW, a bit more idiomatic Elixir would be:
def test(conn, _params) do
raw_skey = File.read!("/home/danish/www/apis/signtest/keys/private_key.pem")
[enc_skey] = :public_key.pem_decode(raw_skey)
skey = :public_key.pem_entry_decode(enc_skey)
string = ~s("MachineName":"DESKTOP-04VG548","Userame":"inder","Timestamp":"2018-10-26T20:58:48.7840832Z"})
signature =
string
|> :public_key.sign(:sha256, skey, rsa_padding: :rsa_pkcs1_padding)
|> Base.encode64
IO.puts("signature")
IO.inspect(signature)
json conn, "ok"
end

This line (above) is unnecessary: your call to :public_key.sign already calculates a SHA256 over the input, so right now the input string is hashed twice. Just pass string instead of msg to the sign function.

Your content variable is already a Binary (an Elixir string is a Binary) so it is already “bytes”.
Your code looks complete to me. Where are you having problems?
