#Customize Harbor auth with your key and certificate

By default, Harbor use default private key and certificate in authentication. The auth procedure is like [Docker Registry v2 authentication](https://github.com/docker/distribution/blob/master/docs/spec/auth/token.md).

By default, Harbor use default private key and certificate in authentication. The auth procedure is like [Docker Registry v2 authentication](https://github.com/docker/distribution/blob/master/docs/spec/auth/token.md). If you try to connect the registry without authorization, the registry will return `401 Unauthorized`. Then you should make a request to the authorization service for a token. The token is encrypted by the private key. After that, you make a new request with the token to the registry, registry will decrypted the token with the public key in the root.crt. The registry will check the token and authorize the client the access to push/pull images.

you can call it prvtkey.pem or other names you like.

```sh

openssl req -new -x509 -key private_key.pem -out root.crt -days 1095
