John,
I believe what you need to do is export the Certificates from the IIS
servers, they will be saved in a .pfx file, which is the PKCS12 format.
OpenSSL can convert these into the PEM format that squid supports, these
commands will give you the desired output.
Exports the Certificate:
openssl pkcs12 -in server.pfx -out server.crt -nodes -nokeys -clcerts
Exports the Private Key (Note will not be encrypted, store in safe place):
openssl pkcs12 -in server.pfx -out server.key -nodes -nocerts -clcerts
The openssl man page and the pkcs12 man page will have more information about
these options if you need them.
Thanks,
