I'm trying to import a self signed root certificate for our enterprise into a Lion machine's key chain and I'm getting an error message: "An error occured. Unable to import "<cert name>" Error -67762" The certificate has a key length of 8192 bits, signature algorithm of SHA256RSA. The subordiant certificate with a key length of 4096 bits, signature algorithm of SHA256RSA. Is there a limitation on the certificate key length that OS X Lion supports? Is this planned to be addressed in an update, or is there a way to change this?
