How to use

Generate certificate hash

In order to use the client, it is necessary to generate an endpoint certificate hash.

Using OpenSSL

openssl s_client -connect <HOST>:443 -servername <HOST> </dev/null 2>/dev/null \
  | openssl x509 -pubkey -noout \
  | openssl pkey -pubin -outform DER \
  | openssl dgst -sha256 -binary \
  | openssl base64

Use the Client

final client = SecureClient();
final requestResponse = await client.httpRequest(
  certificateHash: "Mh7ufr6Yepdwv4IGnMFCJcVG9P0YeIqzaMr+euJo0/U=",
  method: 'GET',
  url: 'https://jsonplaceholder.typicode.com/posts/1',
  headers: {'Content-type': 'application/json; charset=UTF-8'},
);
print(requestResponse);
