x509

[Aaron Galea]

Hi,   Not sure whether this question is in its appropriate place but I have a problem when creating a certificate Payload in ISAKMP. In RFC2408 it mentions 3 types of X.509 certificates, mainly:   X.509 Certificate - Signature                    4 X.509 Certificate - Key Exchange            5 x.509 Certificate - Attribute                    10 Does anyone know what is the difference between them??? or if there is any document that explain this???   Thanks, Aaron
