Can I use the same SSL certificate on multiple ports?
1 Answer. Yes, absolutely – those services can both use the same certificate.
Can I use different port for https?
The port number is not “magic”, you can use any port from 1-65535 you like. There are only 2 conditions: Both the server and the client have to (agree to) use the same port number. Ports in the range 1-1023 are “well known ports” which are assigned worldwide to specific applications or protocols.
Does SSL have to be on port 443?
SSL/TLS does not itself use any port — HTTPS uses port 443. That might sound kind of snooty, but there’s an important distinction to be made there. It enables other protocols, like HTTPS or DNS over TLS. Now, each one of those uses a dedicated port, but SSL/TLS itself is not exclusive to either of those.
Are certificates port specific?
There is no standard for storing a port number in the certificate, and no client will verify the presence of that port number anyway, so, in short words: certificates are not port-specific.
Does SSL certificate include port?
1 Answer. No, the certificate contains the DNS name and the port number is not part of the DNS name of your server. Therefore just use the server name without protocol specification and port.
Does port 80 need to be open for HTTPS?
It isn’t mandatory. You can listen only for secure HTTPS connection on port 443. Try to comment out the port 80 and it should work.
Can I use a different port than 443?
Short answer: yes, you can! Long answer comes here: Can I use another port other than 443 for SSL communication? SSL is in no way tied to a single port value; in fact, as a protocol, it can be used over any transport medium, as long as that medium provides a bidirectional stream for arbitrary bytes.
How to select two different SSL certificates at once?
If i add 2 bindings for https and port 443 i can’t select 2 different certificates (when i change one binding it changes the other). There is a way to solve this without using different port or splitting to 2 different websites? Thanks! There is a simple way to do, tick the “Require Server Name Indication” in “Bindings…”.
Why are SSL certificates issued against different IP addresses?
This is the error I get when trying to use it on the same ports hence I use different ports for the domains First of all SSL certificates are most commonly issued against domain names instead of IP addresses. In your scenario you have one IP address so only one certificate can be issued against one IP address.
Is it possible to make domaina have same SSL cert as port 444?
Now domainA on port 80 has a self signed certificate from IIS. DomainA on port 444 has a real certificate from our CA. Is it possible to make the port 80 domainA have the same SSL cert as the port 444 one?
Is there another port other than 443 for HTTPS / SSL?
443 port is typically used for HTTPS/SSL. But is it the only option we can choose for HTTPS/SSL communication. If not, why? The port number is not “magic”, you can use any port from 1-65535 you like.
