openssl组件:
openssl: 多用途命令行工具,各功能分别使用子命令实现
libcrypto: 公共加密库
libssl: ssl协议的实现
PKI:Public Key Infrastructure
签证机构:CA
注册机构:RA
证书吊销列表:CRL
证书存取库:
openssl建立私有CA:
1、生成密钥 2、自签署证书 节点: 1、生成密钥对儿 2、生成证书签署请求 3、把请求发送给CA CA: 1、验正请求者信息;RA 2、签署证书; 3、把签好的证书发送给请求者;

二、节点申请证书: (一) 节点生成请求 1、生成密钥对儿 # (umask 077; openssl genrsa -out /etc/httpd/ssl/httpd.key 2048) 2、生成证书签署请求 # openssl req -new -key /etc/httpd/ssl/httpd.key -out /etc/httpd/ssl/httpd.csr 3、把签署请求文件发送给CA服务 # scp (二) CA签署证书 1、验正证书中的信息; 2、签署证书 # openssl ca -in /path/to/somefile.csr -out /path/to/somefile.crt -days N 3、发送给请求者; 三、吊销证书 (一)节点 1、获取证书serial # openssl x509 -in /path/to/certificate_file.crt -noout -serial -subject (二) CA 2、根据节点提交的serial和subject信息来验正与index.txt文件中的信息是否一致; 3、吊销证书 # openssl ca -revoke /etc/pki/CA/newcerts/SERIAL.pem 4、生成吊销证书的编号(如果是第一次吊销) # echo 00 > /etc/pki/CA/crlnumber 5、更新证书吊销列表 # cd /etc/pki/CA/crl/ # openssl ca -gencrl -out thisca.crl 如果需要,查看crl文件的内容: # openssl crl -in /path/to/crlfile.crl -noout -text
