Renew pfx file certificate

Question

I have bundled a pfx certificate within an application for a user, however now it appears that the certificate has been expired.

Is there anyway for me to renew the certificate on my side (server) without distributing the renewed certificate to the user ?

Answer 1

No, it would seriously undermine the whole idea of trust in certificates for things that should stay secure.

If you check your certificates with openssl verfify be sure to also add -verbose and -issuer_check

Remember that for a certificate to be valid, all certificates in the chain (up to the Root CA) need to be valid and in the trusted CA store and not on a revocation list.
