Encrypting header value

Hi, is there a possibility to encrypt an arbitrary header value in Traefik? Suppose I have configured in my docker-compose.yml:

pypi:
  labels:
      - "traefik.enable=true"
      - "traefik.http.routers.pypi.rule=Host(`pypi.localhost`)"
      - "traefik.http.routers.pypi.entrypoints=web"
      - "traefik.http.routers.pypi.middlewares=pypi-auth"
      - "traefik.http.middlewares.pypi-auth.headers.customrequestheaders.Private-Token=v3rys3cr3t"

Is there a way to avoid storing v3rys3cr3t in plaintext? Similar as it can be done e.g. for the basic auth.
