描述
OpenSSL 是一个加密工具包,实现了安全套接字层 (SSL) 和传输层安全 (TLS) 网络协议以及它们所需的相关加密标准。
openssl程序是一个命令行程序,用于从 shell使用 OpenSSL加密库的各种加密功能。它可用于
o Creation and management of private keys, public keys and parameters # 私钥、公钥和参数的创建和管理
o Public key cryptographic operations # 公开密钥加密操作
o Creation of X.509 certificates, CSRs and CRLs # 创建X.509证书、CSR和CRL
o Calculation of Message Digests and Message Authentication Codes # 计算消息摘要和消息验证码
o Encryption and Decryption with Ciphers # 使用密码进行加密和解密
o SSL/TLS Client and Server Tests # SSL/TLS客户端和服务器测试
o Handling of S/MIME signed or encrypted mail # 处理S/MIME签名或加密邮件
o Timestamp requests, generation and verification # 时间戳请求、生成和验证
