encryption.Perhaps some people will have some misunderstanding about SSL certificate and Web encryption, think that Web encryption is to take the user's browsing record to make hidden processing. In fact, this is not the case, the HTTPS website that deploys the SSL certificate is to protect the communication between the user and the server, ensuring that the user is safe to trade on the network. and websites protected by SSL certificates can prevent others from tampering with the content.SSL Ce

OpenSSL vulnerability versions include: 1.0.1f, 1.0.1e, 1.0.1d, 1.0.1c, 1.0.1b, 1.0.1a, 1.0.1. The "Heartbleed" vulnerability was fixed in the OpenSSL 1.0.1g release.

focused on reducing the energy consumption when processing packets.There are still new drivers added to the kernel. In each kernel release cycle, an average of 60 to 80 new or upgraded drivers are added.Another major update is the real-time kernel patch, which was introduced for the first time in version 4.0, with the benefit that system administrators can make kernel patches in a production environment without needing to restart the system. When the required elements of the patch are ready, th

vulnerability, it found that most websites encrypted via the SSL protocol use an open source package called OpenSSL. Because this is the Internet application the most extensive secure transmission method, by the net silver, the online payment, the e-commerce website, the portal website, the e-mail and so on important website widespread use, therefore this flaw affects the broad scope. The OpenSSL vulnerability not only affects sites beginning with HTTPS, but hackers can also exploit this vulner
