Openssl ca命令

一、简介

ca命令能够签发证书请求文件以及生成CRL列表

 

二、语法

openssl ca [-verbose] [-config filename] [-name section] [-gencrl] [-revoke file][-crl_reason reason] [-crl_hold instruction] [-crl_compromise time] [-crl_CA_compromise time ] [ -subj subj] [-crldays days] [-crlhours hours] [-crlexts section] [-startdate date] [-enddate date][-days arg] [-md arg] [-policy arg] [-keyfile arg] [-keyform arg] [-key arg] [-passin arg] [-cert file][-selfsign] [-in file] [-out file] [-notext] [-outdir dir] [-infiles] [-spkac file] [-ss_cert file] [-preserveDN] [-batch] [-msie_hack] [-extensions section][-utf8] [-create_serial] [-multivalue-rdn] [-sigopt] [-noemailDN][ -crlsec] [-extfile file] [-updatedb] [ -engine id ]

 -subj arg       - Use arg instead of request's subject
 -utf8           - input characters are UTF8 (default ASCII)
 -multivalue-rdn - enable support for multivalued RDNs
 -extensions ..  - Extension section (override value in config file)
 -extfile file   - Configuration file with X509v3 extentions to add
 -crlexts ..     - CRL extension section (override value in config file)
 -engine e       - use engine e, possibly a hardware device.
 -status serial  - Shows certificate status given the serial number
 -updatedb       - Updates db for expired certificates

 

三、实例

1、签发证书请求文件

openssl ca -in cert_req.pem -extensions v3_ca -out newcert.pem

或

openssl ca -config openssl.cnf -name CA_default -days 365 -md sha1 -policy policy_anything -cert demoCA/cacert.pem -in cert_req.pem -out cert1.pem -preserveDN -noemailDN -subj /CN=CN/O=JS/OU=WX/cn=myname -extensions myexts

2、撤销证书

openssl ca -revoke newcert.pem

3、生成crl

openssl ca -gencrl -out crl.crl -config /root/workspace/testssl/openssl/apps/openssl.cnf

设置原因、挂起处理方法

openssl ca -gencrl -crl_reason keyCompromise -crl_compromise 20010101030303Z  -crl_hold holdInstructionReject -crl_CA_compromise  20020101030303Z -crldays 10 -out crl2.crl
