Introduction
openssl is a powerful secure socket cryptographic library, including three main functional parts:
- openssl: a versatile command line tool
- libcrypto: encryption algorithm library
- libssl: Encryption module application library, which implements ssl and tls
With the help of openssl, you can achieve: key certificate management, symmetric encryption and asymmetric encryption.
There are two ways to install openssl:
- Download the source code and compile it yourself
- Use ready-made installation packages
Stop talking nonsense and go straight to the topic.
