Google recaptcha public and private key

Question

We are using google recaptcha in one of our projects. To get the private and public key for captcha we just used the url as http://localhost:4345/. Can the same private and public key be used in live site also.

Answer 1

Yes that's perfectly ok to use the same key pair for both local testing and server deployment (as long as you keep your private key a secret). On the other hand, if you did not select the "global key" option, the keys are unique to your domain and sub-domains (event though all keys will again work on localhost without any problem).
