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

DES (Data Encryption Standard) is a group symmetric cipher algorithm . des employs a 64-bit packet length and a 56-bit key length , which takes 64-bit inputs through a series of transformations to get 64-bit output. Decryption uses the same steps

OpenSSL introduction and compilation steps on Windows, Linux, and Mac systems OpenSSL Introduction: OpenSSL is a powerful Secure Socket Layer password library, which includes major cryptographic algorithms, common keys, certificate encapsulation

1. Overview of symmetric encryption algorithmsOpenSSL's cryptographic algorithm library provides a rich symmetric encryption algorithm that can be used in the form of symmetric cryptographic algorithm directives provided by OpenSSL, or by invoking

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]

1. Overview of Asymmetric encryption algorithmsAsymmetric encryption algorithm is also called Public key algorithm, which solves the problem of symmetric encryption algorithm key distribution, the basic features of asymmetric encryption algorithm

In HTTPS learning note two, the concept of digital certificates has been clarified, composed and how the client validates the server-side certificate during the HTTPS connection process. This chapter describes how to use the OpenSSL library to
