Package captcha provides an easy to use, unopinionated API for captcha generation.
Why another captcha generator?
I want a simple and framework-independent way to generate captcha. It also should be flexible, at least allow me to pick my favorite font.
install
go get github.com/steambap/captcha
usage
func handle(w http.ResponseWriter, r *http.Request) {
// create a captcha of 150x50px
data, _ := captcha.New(150, 50)
// session come from other library such as gorilla/sessions
session.Values["captcha"] = data.Text
session.Save(r, w)
// send image data to client
data.WriteImage(w)
}
