Implementing HMAC-SHA256 Authentication for OKEx V5 REST Endpoints in C#
The OKEx V5 authentication protocol requires generating a cryptographic signature for every REST API call. The signature is derived by concatenating the ISO 8601 timestamp, HTTP method, request path, and request body (if applicable). This combined string is hashed using the HMAC-SHA256 algorithm with the API secret key, and the resulting byte s ...
