以下是我将文件分段摘抄出来并进行解释的
默认段 # # OpenSSL example configuration file. # This is mostly being used for generation of certificate requests. # # This definition stops the following lines choking if HOME isnt # defined. 定义当前目录变量以及随机数的文件路径变量 HOME . RANDFILE $ENV::HOME/.rnd # Extra OBJECT IDENTIFIER info: #oid_file $ENV::HOME/.oid oid_section new_oids # To use this configuration file with the -extfile option of the # openssl x509 utility, name here the section containing the # X.509v3 extensions to use: # extensions # (Alternatively, use a configuration file that has only # X.509v3 extensions in its main [ default] section.) [ new_oids ] # We can add new OIDs in here for use by ca, req and ts. # Add a simple OID like this: # testoid11.2.3.4 # Or use config file substitution like this: # testoid2${testoid1}.5.6 # Policies used by the TSA examples. tsa_policy1 1.2.3.4.1 tsa_policy2 1.2.3.4.5.6 tsa_policy3 1.2.3.4.5.7 CA段 #################################################################### [ ca ] default_ca CA_default # The default ca section #################################################################### [ CA_default ] dir /etc/pki/CA # Where everything is kept certs $dir/certs # Where the issued certs are kept已颁发的证书路径即CA或者自签的 crl_dir $dir/crl # Where the issued crl are kept 已颁发的crl存放目录 database $dir/index.txt # database index file. #unique_subject no # Set to no to allow creation of # several ctificates with same subject. new_certs_dir $dir/newcerts # default place for new certs.将来颁发的证书存放路径 certificate $dir/cacert.pem # The CA certificate CA自己的证书文件 serial $dir/serial # The current serial number提供序列号的文件路径 crlnumber $dir/crlnumber # the current crl number 当前crl序列号 # must be commented out to leave a V1 CRL crl $dir/crl.pem # The current CRL 当前crl文件 private_key $dir/private/cakey.pem# The private key 签名时需要的私钥即CA自己的私钥 RANDFILE $dir/private/.rand # private random number file 提供随机数的文件 x509_extensions usr_cert # The extentions to add to the cert添加到证书中的扩展项 # Comment out the following two lines for the traditional 证书展示格式一般不用修改使用默认即可 # (and highly broken) format. name_opt ca_default # Subject Name options cert_opt ca_default # Certificate field options # Extension copying option: use with caution.扩展项的使用需要谨慎 生成证书时扩展项的扩展可复制属性copy_extensions取值为none/copy或copyall。 如不设置则默认为none,简单使用时设置为none或者不设置不建议设置为copyall # copy_extensions copy # Extensions to add to a CRL.
