While a registration authority can help a CA by identity proofing certificate applicants, it is again up to the browser manufacturer to install them. While the certificate authority signs its own root certificate and vouches for itself, it is up to the browser manufacturer to install them. The list of trusted enterprise certificate authorities should be delivered to the browser by group policy. The list of trusted third-party certificate authorities is installed by the browser manufacturer and updated when the browser is updated. Blowfish is a very strong symmetric algorithm with up to a 448 bit key. As computers get faster one can increase the work factor and the hash will get slower.Although bcrypt is derived from Blowfish, Blowfish does not provide key stretching. Because of this, bcrypt can keep up with Moore's law. Bcrypt uses a variant of the Blowfish encryption algorithm's keying schedule, and introduces a work factor, which allows one to determine how expensive the hash function will be.

The added computational work makes password cracking much more difficult, and is known as key stretching.- Bcrypt. The following provide key stretching and do not reveal compromised certificates:- PBKDF2 (Password-Based Key Derivation Function 2) applies a pseudorandom function, such as a cryptographic hash, cipher, or HMAC to the input password or passphrase along with a salt value and repeats the process tens of thousands of times to produce a derived key, which can then be used as a cryptographic key in subsequent operations. OCSP speed is faster than downloading a CRL. The Online Certificate Status Protocol (OCSP) is the protocol used by browsers to obtain the revocation status of a digital certificate attached to a website. OCSP allows users with expired certificates a grace period, so they can access servers for a limited time before renewing. The server sends back a response of "current", "expired," or "unknown." The protocol specifies the syntax for communication between the server (which contains the certificate status) and the client application (which is informed of that status). When a user attempts to access a server, OCSP sends a request for certificate status information. Online Certificate Status Protocol (OCSP.) The OCSP overcomes the chief limitation of CRL: the fact that updates must be frequently downloaded to keep the list current at the client end. The main disadvantages of implementing a certificate revocation list is that it is a single point of failure, is expensive to maintain, and is slower than OCSP. The CRL should be checked regularly to avoid using compromised certificates. So this would be the very last option for me.The following are ways to check for revoked certificates:- Certificate Revocation List (CRL.) The CRL contains a list of certificates that are compromised and invalid.

But, I have to say that I don't really know how to configure the RPi like this, and if the RPi is not running, no one could access the internet. The only other way I could imagine is to route all network traffic over the RaspberryPi and forward it to the router, allowing me to use iptables to drop all connections from a specific MAC address.
And most importantly, the whole thing could be bypassed by configuring a static IP address in the devices network settings. to 10m) would be an option to solve the issue, but I don't know if this has a negative side effect for the client asking every 10 minutes for a new DHCP lease.
Reducing the lease time for this specific client (e.g. I've already played around with dhcp-ignore and dhcp-mac, but of course this doesn't work if the client already has an IP address, so I have to remove the lease manually from the dnsmasq.leases file. I want to achieve this with a RaspberryPi, which currently acts as a DHCP server in my network (running dnsmasq). I'm looking for a way to restrict access to the internet from my home network for specific devices without doing any configuration on the device itself.
