With the Internet security and personal privacy increasingly critical today, encryption technology becomes particularly important and indispensable. In the password snow, encryption refers to the concealment of plaintext information, making it
About OpenSSL OpenSSL
SSL is an abbreviation for the Secure Socket Layer protocol, which provides covert transmission over the Internet. Netscape Company introduced the SSL protocol standard at the same time as the first web browser, there are now 3.
OpenSSL is an open source SSL implementation. The simplest and most important application based on the OpenSSL directive is to use Req, CAs, and X509 to issue a certificate.OpenSSL provides command-line options and interactive two ways to perform

OpenSSL: Commonly known as Secure socketsit can achieve Data encryption:SSL is all called: Secure Socket Layer can provide secret transmission on the Internet, the goal is to ensure the confidentiality and reliability of two application
OpenSSL high-risk vulnerability: allows hackers to decrypt HTTPS traffic (CVE-2016-0701)
Maintainers of the OpenSSL encrypted code library announced that they had fixed a high-risk vulnerability. This vulnerability allows hackers to obtain keys
To generate a certificate in OpenSSL, follow these steps:1. generate an RSA private key file and generate a certificate application for this private key file.First, you must enter a password to encrypt the RSA private key file and ask the user to
