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?
Where Next?

BTW, just FYI and FWIW, a bit more idiomatic Elixir would be:

I think @easco’s answer is pretty much correct, but I’m guessing what you’re after is maybe a list of bytes? Since your C# code returns an array of bytes? You can use
:erlang.binary_to_list/1ondigestto convert the binary to a list.voltone
This line (above) is unnecessary: your call to
:public_key.signalready calculates a SHA256 over the input, so right now the input string is hashed twice. Just passstringinstead ofmsgto the sign function.easco
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?
