# Description: This function handles the deployment of certificates to multiple services.
#              It processes the provided certificate files and deploys them according to the
#              configuration specified in the multideploy file.
#
# Parameters:
#   _cdomain     - The domain name for which the certificate is issued.
#   _ckey        - The private key file for the certificate.
#   _ccert       - The certificate file.
#   _cca         - The CA (Certificate Authority) file.
#   _cfullchain  - The full chain certificate file.
#   _cpfx        - The PFX (Personal Information Exchange) file.

#   file are used.
