CMAC Calculation AES-128

Hi there, i’m new to Vault, i was wondering if there is any possibility to do a CMAC calculation with a saved AES key inside vault. This would avoid exposing the key outside vault to do the calculation.
If there is not, can i write a plugin to do it?
Thanks.

I think Vault only supports HMAC currently.

You can develop your own plugins - see the plugin development guide.
