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
Let's introduce the next three encryption methods:
Symmetric encryption
Public Key Cryptography
One-way encryption
Symmetric encryptionImplementation Tool OpenSSL ENC introduction[[email protected] sh]# man encenc -
Secure programming with the OpenSSL API
First, Concept: 1. What is SSL. SSL is an abbreviation, the full name is Secure Sockets Layer. It is the standard that supports secure communication over the Internet and integrates data cryptography into
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:
Install OpenSSL in Ubuntu
I. Brief Introduction to OpenSSL
OpenSSL is a powerful secure socket-layer cryptographic library that includes major cryptographic algorithms, common keys, certificate encapsulation management functions, and SSL protocols,
I. Brief Introduction to OpenSSL is a powerful Secure Socket Layer password library, which includes the main cryptographic algorithms, common keys, certificate encapsulation management functions, and SSL protocols, and provides a wide range of
OpenSSL encoding rules1. data encoding format
Openssl data encoding rules are based on ans.1. What is ans.1? An Explanation on top of the project
ASN.1 (Abstract Syntax Notation One) is a structured Description Language, which consists of two parts:
What is CA:
CA (Certificate authority) is the abbreviation of digital Certificate Certification Center, refers to the issuing, management, abolition of digital certificate institutions.
The role of a CA is to check the legitimacy of the identity of
