tls encryption gmail

With the development of the Internet, the demand for the network speed is more and more high, especially in the case of vigorously developing HTTPS, the TLS encryption protocol becomes very important. And Pat the cloud in the popularization of HTTPS and performance optimization, always do their own efforts and contributions. At the beginning of 2018, the cloud CDN network was deployed with

Can you introduce the problems found in the RC4 encryption algorithm recently? In this regard, what security risks do HTTPS network connections face? How should enterprises ensure that they are not attacked by this vulnerability? Michael Cobb:RC4 (Rivest password 4) was designed by Ron Rivest of RSA Security in 1987. Due to its speed and simplicity, this encryption algorithm has become the most widely used

problem with the earlier version of Sha, currently using SHA-1, which can produce a 160-bit digest, This makes it more effective against brute-force attacks than 128-bit hashes.Since the one-way hashing algorithm is public, others can change the original text before generating another digest. The solution to this problem can be achieved by HMAC (RFC 2104), which contains a key that can be identified only by people with the same key.Four key negotiation processBecause of the slow speed of symmet

The best way to learn the TLS protocol is to look at the RfC, but if there is no basic understanding of the secure transport protocol, it is difficult to read the details and design principles of the RFC, so here in order to be able to further understand the TLS protocol, put some basic knowledge here, is a sweep blind.1. The difference between TLS and SSL: SSL i

SuperSocket supports transport layer encryption (TLS/SSL) In Sync Mode ). First, you need to prepare the Certificate file (with a private key) for encryption ). Certificates used for testing can be generated (http://supersocket.codeplex.com/releases/view/59311) by the CertificateCreator of the SuperSocket, and then (*. pfx) is imported into the trusted Certifica

So many of the bank's web sites or email and other security-level services will use the HTTPS protocol. Introduction to HTTPS HTTPS is actually made up of two parts: http + ssl/tls, which is a module that adds a layer of
