Is is feasible to use the single self-signed certificate on multiple machines which are two way ssl communicating.

Question

I have came across a situation where I need to have same certificate on 4 machines which are communicating with each other in a two way ssl.

Will it be problematic to have same certificate on client as well as server side for two way ssl communication.?

Thanks, Vinds

Answer 2

A server certificate usually lists its host name as the common name component of the subject, and it can also appear in the subject alternative names too. When establishing a connection, most applications expect the host name in the certificate to match a name of the host to which the connection is made; this is application level though, and not part of the SSL protocol itself.

Re-using the same certificate for many clients is not a problem.
