How to change REDASH_SECRET_KEY?

Hi.

Is there a feature to re-encrypt data source options with new REDASH_SECRET_KEY?

If REDASH_SECRET_KEY is leaked, I want to change REDASH_SECRET_KEY and encrypt data source options with the new REDASH_SECRET_KEY.

I checked documents and source code but I can’t find about it.

Could you help me?
Thanks.
