x509

I have successfully setup DKIM with dkimproxy with a self-signed certificate. Now I want to use an existing X.509 certificate. The script that comes with dkimproxy on Ubuntu to generate the DNS records results in the following broken information (only the start):

postfix._domainkey IN TXT "k=rsa; p=-----BEGIN CERTIFICATE----- MIIHCDCCBfCgAwIBAgICP4AwDQYJKoZIhvcNAQEFBQAwgYwxCzAJBgNVBAYTAklM MRYwFAYDVQQKEw1TdGFydENvbSBMdG

This seems broken to me but I haven't found:

what's the format the public.key should be for dkimproxy?
how to extract that information from the certificate file?
