Openssl is an open-source implementation of SSL (applications can be downloaded for free). It is a secure and confidential program that is mainly used to improve the security of remote login access. It is also one of the tools currently used in encryption algorithms and has powerful functions.Openssl provides a security protocol for network communication security and data integrity, including key algorithms, common key and certificate encapsulation ma

openssl source program is compiled and installed, we not only get two useful library files libcrypto. a and libssl. a. It also contains an example of a very complete function provided by the two libraries, that is, the openssl executable file and other auxiliary files, the functions completed in this example include key pair generation, certificate application,

OpenSSL exposed the most serious security vulnerability of the year. This vulnerability was named "heartbleed" in the hacker community. The "heartbleed" vulnerability will affect at least 0.2 billion Chinese netizens. It is initially evaluated that a batch of mainstream websites with https logon methods are recruited by no less than 30% of websites, these include the most common shopping, online banking, social networking, portals, microblogs, mailbo
