Transferred from: http://netsecurity.51cto.com/art/201301/378513.htm1. IntroductionOpenSSL is a powerful cryptographic toolkit. Many of us already use OpenSSL to create RSA private keys or certificate signing requests (CSRs). But have you ever known
Using the OpenSSL library for RSA, AES data encryption OpenSSL is a library that can be easily encrypted and decrypted, and can be used to encrypt data that needs to be transmitted over the network. Asymmetric encryption can be used: Public key
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

About OpenSSL OpenSSL
SSL is an abbreviation for the Secure Socket Layer protocol, which provides covert transmission over the Internet. Netscape Company introduced the SSL protocol standard at the same time as the first web browser, there are now 3.
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
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
