The DH implementation of OpenSSL in the CRYPT/DH directory, each source code is as follows:(1) dh.hThe DH key method data structure and various functions are defined.(2) dh_asn1.cThe DER-codec implementation of the DH key parameter.(3) DH_LIB.CThe
OpenSSL is an open source SSL implementation. The simplest and most important application based on the OpenSSL directive is to use Req, CAs, and X509 to issue a certificate.OpenSSL provides command-line options and interactive two ways to perform

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
DH key exchange and ECDH principleTime 2013-06-24 18:50:55 csdn Blogsimilar articles (0) original http://blog.csdn.net/sudochen/article/details/9164427 let's take Alice and Bob as an example to describe the principle of Diffie-hellman key exchange.
8.1 Overview of asymmetric cryptographic algorithm directivesA. Asymmetric encryption algorithm also becomes public key algorithm, which solves the problem that the symmetric encryption algorithm key needs to be pre-allocated. Asymmetric Encryption
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
Objective:In the early days of the Internet, the number of hosts connected to the Internet was small and applications were few, so the network protocols that were designed early in the morning did not take into account the concept of network
