BrieflyOpenSSL is a strong Secure Sockets Layer cipher library that includes key cryptographic algorithms, common key and certificate encapsulation management functions, and SSL protocols, and provides a rich set of applications for testing or other

Symmetric encryption tool, understanding the principle of symmetric encryption is very simple, the principle section is shown below. OpenSSL enc-ciphername [-in filename] [-out filename] [-pass arg] [-e] [-d] [-a/-base64] [-k password] [-S SALT]

As the title shows, the overall section is divided into three parts:First, install OpenSSL under WIN10 and then generate the RSA public and private key via the OpenSSL tool(1) Win10 under the installation of OpenSSL required tools are:
