Yes you can. But they will be completely pointless if you don't pin their thumbprint to a specific application. Imagine for a second what you want to use the certificate for: The certificate should provide authenticity, i.e. you want to verify that an entity that claims to be entity X is actually entity X. Consider the following example: When you get a CA-...

This has been answered, but if anyone's still looking for a no-prompt, cli-only method to create a self-signed root cert (without CAs or CSRs) and don't mind using Java keytool, here's an alternative: Generate a PKCS12 keystore with keytool keytool -genkeypair \ -keyalg RSA \ -keysize 3072 \ -alias titan \ -dname "CN=titan,OU=Engineering,O=Titan Corp.,...

TL;DR: It's not permitted; it's not technically impossible. Assuming you're not talking about a certificate that's been held, it would be against the rules for a certificate, once revoked, to be unrevoked.

Using CAA DNS records for internal networks doesn't really make sense, especially when you're using a .local domain. Simply put: The way CAA records work is that an issuing CA will check the CAA records of a domain through public DNS records but only if the issuing CA is told to do so. Public CAS are required to do that. But a public certificate authority ...

Mozilla operates this site, but all of the major Root certificates stores vendors (Mozilla, Microsoft, Google, Cisco, and Apple) contributes data to the common database. All the major root certificate store maintainers publishes all the root certificate that they have in their root store ...

In most browsers, you should be able to view the certificate for a site, and follow the chain up to the root certificate. For example, in Firefox for security.stackexchange.com, you can follow the following steps, and see that the root certificate of the chain is DST Root X3. 1) Navigate to security.stackexchange.com, and click the green padlock in the ...

Mitigating Effects of Malicious/Compromised Certificate Authorities There aren't very many things you can do yourself as the client, but I will outline several solutions available anyway. Remove Untrusted Certificates If there are CAs that are trusted by your browser and/or operating system that you do not personally trust, you should remove them. This is ...

If it's your router then fix it to where you can make that ip on the router gain access to the YouTube, gmail, or other websites again. It has been you or ...

Is it even possible to "recycle" my valid personal certificate to be used in the RADIUS server? A certificate is valid only for the domains listed in the certificate. Since your private domain is likely not the domain of the radius server you cannot reuse your certificate there. Apart from that it is a bad idea to give your secret key to the school, since ...

While it is the typical case of https eavesdropping, most likely there is no malicious intent in the background. For example, the router can provide some web filtering or other defense for you with it. Furthermore, it is impossible to be done without your consent: the manufacturer can't create such SSL certificates to the domains you visit, what are ...
