Package captcha provides an easy to use, unopinionated API for captcha generation.
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.
go get github.com/steambap/captcha
funchandle(w http.ResponseWriter, r*http.Request) {
// create a captcha of 150x50pxdata, _:=captcha.New(150, 50)
// session come from other library such as gorilla/sessionssession.Values["captcha"] =data.Textsession.Save(r, w)
// send image data to clientdata.WriteImage(w)
