1、对称加密算法 对称加密(也叫私钥加密)指加密和解密使用相同密钥的加密算法。有时又叫传统密码算法,就是加密密钥能够从解密密钥中推算出来,同时解密密钥也可以从加密密钥中推算出来。而在大多数的对称算法中,加密密钥和解密密钥是相同的,所以也称这种加密算法为秘密密钥算法或单密钥算法。它要求发送方和接收方在安全...

默认情况下PostgreSQL 读取openssl的配置文件openssl.cnf, 在opensslversion-d返回的目录中. 当然也可以使用OPENSSL_CONF环境变量读取指定的配置的文件. PostgreSQL reads the system-wide OpenSSL configurationfile.Bydefault, thisfileis named openssl.cnf and is locatedinthe directory reportedbyopensslversion-d. This...
OpenSSL是一款开源工具包,用于实现安全套接层(SSL)和传输层安全(TLS)协议,它对于大多数负责安全网络工作的Linux管理员来说是必不可少的一款日常工具。但是OpenSSL还包括丰富的功能,连经验老到的资深人士也可能不太熟悉这些功能。
