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

SSL Overview SSL is securesocketlayer ( SecuritySocket Layer Protocol), which can provide confidential transmission over the Internet. Netscape released the first web browser and put forward the SSL protocol standard, which currently has version 3.0.

OpenSSL req is used to generate a certificate request for a third party authority CA to issue and generate the certificate we need. The Req command can also invoke the X509 command for format conversion and display information such as Text,modulus

OpenSSL symmetric encryption algorithm commands 1. symmetric encryption algorithm Overview The openssl Encryption Algorithm Library provides a wide range of symmetric encryption algorithms. We can use the symmetric encryption algorithm commands
