echo basic auth

Basic Auth middleware with constant time equality checks and optional IP whitelisting for Echo framework. CIDRs are supported for IP whitelisting as well

Usage

auth := &echobasicauth.Auth{Login: "test", Password: "test", IPs: []string{"127.0.0.1", "10.0.0.0/24"}}
e.Use(echobasicauth.NewMiddleware(auth))
// or you can use echobasicauth.NewValidator(auth) if you want to define the middleware yourself

IP validation without credentials

You can use AllowedIP directly to check if an IP is allowed without validating credentials:

auth := &echobasicauth.Auth{IPs: []string{"127.0.0.1", "10.0.0.0/24"}}
if auth.AllowedIP(c.RealIP()) {
    // IP is allowed
}
