How to separate parameters and use the same parameters to speed up the private key and certification generation in RSA [closed]

Posted on by

I want to generate multiple private keys and certifications in a short time. It means it is not a good idea to generate one by one. I know it can share some processes or parameters to generate multiple private keys and certificates. It can… Continue reading How to separate parameters and use the same parameters to speed up the private key and certification generation in RSA [closed]→

How can we ensure non-repudiation without a personal certificate (eg. using ID authentication)

Posted on by

I need a help to understand some specific points about non-repudiation, nonetheless I implemented some authentication methods:

Digital Signature Authentication;
CHAP (Challenge Authentication Protocol)
Zero-knowledge password proof

Let… Continue reading How can we ensure non-repudiation without a personal certificate (eg. using ID authentication)→

Should I stop using DSA key algorithm self-signed certificates in production in favor of RSA Certificates?

Posted on by

We use a self-signed certificate with DSA key algorithm (and RSA signature algorithm) for securing a Kafka cluster in production. The access to the Kafka servers is already limited (by firewall) by allowing access only to specific IP subne… Continue reading Should I stop using DSA key algorithm self-signed certificates in production in favor of RSA Certificates?→
