encryption at rest on bigip/http connector
We have a request to send a specific header and a value to the backend servers based on traffic coming in. Im currently testing this via irules. The header value will be a key stored in irule or datagroup. If needed to, is there a way to encrypt/decrypt that header value locally in big-ip? instead of it being in clear text via irule/datagroup/iFile?
An option I thought to maybe use is APM making an api call via http connector to a key vault(e.g. hashicorp vault) somewhere to extract that string in session variable and then use it via irule.
