We noticed in the *oxauth.log* that our oxAuth signing certificates have expired. There is **nothing** in oxTrust about the expiration. This has impaired our production environment, since we cannot use the introspection endpoint with expired certificates. ``` 2020-02-13 16:21:02,551 WARN [qtp804611486-15] [org.xdi.oxauth.model.crypto.AbstractCryptoProvider] (AbstractCryptoProvider.java:219) - WARNING! Expired Key with alias: 88bd81c3-eb69-428f-a0ea-1ae94728bd5b Expires On: 2020-02-12 20:19:18 Today's Date: 2020-02-13 16:21:02 ``` We looked at the [Certificate Management documentation](https://gluu.org/docs/ce/3.1.6/admin-guide/certificate/). The /etc/certs directory has both *oxauth-keys.jks* and *oxauth-keys.json* files, but the documentation only briefly references the *oxauth-keys.json* file, but it does not explain this file at all. The documentation also specifies to use the *oxauth-client.jar* tool in order to create keys. No where in the documentation does it tell how we should go about correctly renewing the oxAuth certificates. There are twelve certificates, with different algorithms. Are we supposed to modify the certificates in both the *oxauth-keys.jks* and the *oxauth-keys.json* files? What is the documented oxAuth certificate renewal process?

Curious about the title. Is there a *How to renew oxauth key automatically* or is it just manual?

It’s manual method.

Mohib, I was unable to call the KeyGenerator using your exact line, but was able to call it with the oxauth-client.jar instead. The problem is that the oxauth-keys.json that is produced is empty.

Sorry... please try this: ``` /opt/jre/bin/java -Dlog4j.defaultInitOverride=true -cp '/home/jetty/lib/*' org.xdi.oxauth.util.KeyGenerator -keystore oxauth-keys.jks -keypasswd <password> -sig_keys RS256 RS384 RS512 ES256 ES384 ES512 PS256 PS384 PS512 RSA1_5 -enc_keys RSA1_5 RSA-OAEP -dnname "CN=oxAuth CA Certificates" -expiration 365 > oxauth-keys.json ```

That worked, but there are a lot less kids in the new JSON file. Is that expected?

I used ldapmodify to replace the JSON in LDAP, but it worked. This would be very nice to have in the oxTrust UI with a renew button. Thanks for your help, Mohib!

Thanks for confirmation, David. Yes.. basically this key generation is automatic from Gluu Server 4.0. Human input won't be required. Even if it's required... there will be script to do all those things together.

Mohib, Here is a script I wrote from my history. https://gist.github.com/davidgvh/738b13b23ad6a217e7e41259ae70d036 Perhaps this can be used by a future version of Gluu Server 3.x to make a single button click button in the UI.
