DomainKeys - where is the private key stored

[gbh]

when you set up domainkeys on a cpanel/whm machine using /usr/local/cpanel/bin/domain_keys_installer where is the publick and private key stored? (I know the public goes into the dns record but I'm looking for where I can find the private key for that pair)
As in where does this script store the private key by default?

many thanks in advance.

Private Keys will get stored in
/var/cpanel/domain_keys/private
