TranslateProject/translated/tech/20150511 OpenSSL command line Root and Intermediate CA including OCSP, CRL and revocation.md

14 KiB
Raw Blame History

OpenSSL命令行生成根CA和中间CA，涵盖了OCSP、CRL和证书撤销

这些是关于使用OpenSSL生成证书授权（CA）、中间证书授权和末端证书的速记随笔，内容包括OCSP、CRL和CA颁发者信息，以及指定颁发和有效期限。

我们将建立我们自己的根CA，我们将使用根CA来生成一个样例中间CA，我们将使用中间CA来签署末端用户证书。

根CA

创建根CA授权目录并切换到该目录：

mkdir ~/SSLCA/root/
cd ~/SSLCA/root/

为我们的根CA生成一个8192位长的SHA-256 RSA密钥：

openssl genrsa -aes256 -out rootca.key 8192

样例输出：

Generating RSA private key, 8192 bit long modulus
.........++
....................................................................................................................++
e is 65537 (0x10001)

如果你想要用密码保护该密钥，请添加-aes256选项。

创建自颁发根CA证书ca.crt；你需要为你的根CA提供一个身份：

openssl req -sha256 -new -x509 -days 1826 -key rootca.key -out rootca.crt

样例输出：

You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:NL
State or Province Name (full name) [Some-State]:Zuid Holland
Locality Name (eg, city) []:Rotterdam
Organization Name (eg, company) [Internet Widgits Pty Ltd]:Sparkling Network
Organizational Unit Name (eg, section) []:Sparkling CA
Common Name (e.g. server FQDN or YOUR name) []:Sparkling Root CA
Email Address []:

创建存储CA序列的文件：

touch certindex
echo 1000 > certserial
echo 1000 > crlnumber

放置CA配置文件，该文件持有CRL和OCSP末端的存根。

# vim ca.conf
[ ca ]
default_ca = myca

[ crl_ext ]
issuerAltName=issuer:copy 
authorityKeyIdentifier=keyid:always

 [ myca ]
 dir = ./
 new_certs_dir = $dir
 unique_subject = no

 OCSP;URI.0 = http://pki.sparklingca.com/ocsp/
 OCSP;URI.1 = http://pki.backup.com/ocsp/

如果你需要设置某个特定的证书生效/过期日期，请添加以下内容到[myca]

# format: YYYYMMDDHHMMSS
default_enddate = 20191222035911
default_startdate = 20181222035911

创建中间1 CA

生成中间CA的私钥： openssl genrsa -out intermediate1.key 4096

生成intermediate1 CA的CSR：

openssl req -new -sha256 -key intermediate1.key -out intermediate1.csr

样例输出：

You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:NL
State or Province Name (full name) [Some-State]:Zuid Holland
Locality Name (eg, city) []:Rotterdam
Organization Name (eg, company) [Internet Widgits Pty Ltd]:Sparkling Network
Organizational Unit Name (eg, section) []:Sparkling CA
Common Name (e.g. server FQDN or YOUR name) []:Sparkling Intermediate CA
Email Address []:

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:

确保中间CA的主体（CN）和根CA不同。

用根CA签署intermediate1 CSR：

openssl ca -batch -config ca.conf -notext -in intermediate1.csr -out intermediate1.crt

样例输出：

Using configuration from ca.conf
Check that the request matches the signature
Signature ok
The Subject's Distinguished Name is as follows
countryName           :PRINTABLE:'NL'
stateOrProvinceName   :ASN.1 12:'Zuid Holland'
localityName          :ASN.1 12:'Rotterdam'
organizationName      :ASN.1 12:'Sparkling Network'
organizationalUnitName:ASN.1 12:'Sparkling CA'
commonName            :ASN.1 12:'Sparkling Intermediate CA'
Certificate is to be certified until Mar 30 15:07:43 2017 GMT (730 days)

Write out database with 1 new entries

生成CRL（同时采用PEM和DER格式）：

openssl ca -config ca.conf -gencrl -keyfile rootca.key -cert rootca.crt -out rootca.crl.pem

openssl crl -inform PEM -in rootca.crl.pem -outform DER -out rootca.crl

每次使用该CA签署证书后，请生成CRL。

如果你需要撤销该中间证书：

openssl ca -config ca.conf -revoke intermediate1.crt -keyfile rootca.key -cert rootca.crt

配置中间CA 1

为该中间CA创建一个新文件夹，然后进入该文件夹：

mkdir ~/SSLCA/intermediate1/
cd ~/SSLCA/intermediate1/

从根CA拷贝中间证书和密钥：

cp ~/SSLCA/root/intermediate1.key ./
cp ~/SSLCA/root/intermediate1.crt ./

创建索引文件：

touch certindex
echo 1000 > certserial
echo 1000 > crlnumber

创建一个新的ca.conf文件：

# vim ca.conf
[ ca ]
default_ca = myca

[ crl_ext ]
issuerAltName=issuer:copy 
authorityKeyIdentifier=keyid:always

 [ myca ]
 dir = ./
 new_certs_dir = $dir
 unique_subject = no
 certificate = $dir/intermediate1.crt
 database = $dir/certindex
 private_key = $dir/intermediate1.key
 serial = $dir/certserial
 default_days = 365
 default_md = sha1
 policy = myca_policy
 x509_extensions = myca_extensions
 crlnumber = $dir/crlnumber
 default_crl_days = 365

 [ myca_policy ]
 commonName = supplied
 stateOrProvinceName = supplied
 countryName = optional
 emailAddress = optional
 organizationName = supplied
 organizationalUnitName = optional

 [ myca_extensions ]
 basicConstraints = critical,CA:FALSE
 keyUsage = critical,any
 subjectKeyIdentifier = hash
 authorityKeyIdentifier = keyid:always,issuer
 keyUsage = digitalSignature,keyEncipherment
 extendedKeyUsage = serverAuth
 crlDistributionPoints = @crl_section
 subjectAltName  = @alt_names
 authorityInfoAccess = @ocsp_section

 [alt_names]
 DNS.0 = example.com
 DNS.1 = example.org

 [crl_section]
 URI.0 = http://pki.sparklingca.com/SparklingIntermidiate1.crl
 URI.1 = http://pki.backup.com/SparklingIntermidiate1.crl

 [ocsp_section]
 caIssuers;URI.0 = http://pki.sparklingca.com/SparklingIntermediate1.crt
 caIssuers;URI.1 = http://pki.backup.com/SparklingIntermediate1.crt
 OCSP;URI.0 = http://pki.sparklingca.com/ocsp/
 OCSP;URI.1 = http://pki.backup.com/ocsp/

修改[alt_names]部分，添加你需要的主体备选名。如果你不需要主体备选名，请移除该部分包括subjectAltName = @alt_names的行。

如果你需要设置一个指定的生效/到期日期，请添加以下内容到[myca]

# format: YYYYMMDDHHMMSS
default_enddate = 20191222035911
default_startdate = 20181222035911

生成一个空白CRL（同时以PEM和DER格式）：

openssl ca -config ca.conf -gencrl -keyfile rootca.key -cert rootca.crt -out rootca.crl.pem

openssl crl -inform PEM -in rootca.crl.pem -outform DER -out rootca.crl

生成末端用户证书

我们使用这个新的中间CA来生成一个末端用户证书，请重复以下操作来使用该CA为每个用户签署。

mkdir enduser-certs

生成末端用户的私钥：

openssl genrsa -out enduser-certs/enduser-example.com.key 4096

生成末端用户的CSR：

openssl req -new -sha256 -key enduser-certs/enduser-example.com.key -out enduser-certs/enduser-example.com.csr

样例输出：

You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:NL
State or Province Name (full name) [Some-State]:Noord Holland
Locality Name (eg, city) []:Amsterdam
Organization Name (eg, company) [Internet Widgits Pty Ltd]:Example Inc
Organizational Unit Name (eg, section) []:IT Dept
Common Name (e.g. server FQDN or YOUR name) []:example.com
Email Address []:

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:

使用Intermediate 1 CA签署末端用户的CSR：

openssl ca -batch -config ca.conf -notext -in enduser-certs/enduser-example.com.csr -out enduser-certs/enduser-example.com.crt

样例输出：

Using configuration from ca.conf
Check that the request matches the signature
Signature ok
The Subject's Distinguished Name is as follows
countryName           :PRINTABLE:'NL'
stateOrProvinceName   :ASN.1 12:'Noord Holland'
localityName          :ASN.1 12:'Amsterdam'
organizationName      :ASN.1 12:'Example Inc'
organizationalUnitName:ASN.1 12:'IT Dept'
commonName            :ASN.1 12:'example.com'
Certificate is to be certified until Mar 30 15:18:26 2016 GMT (365 days)

Write out database with 1 new entries
Data Base Updated

生成CRL（同时以PEM和DER格式）：

openssl ca -config ca.conf -gencrl -keyfile intermediate1.key -cert intermediate1.crt -out intermediate1.crl.pem

openssl crl -inform PEM -in intermediate1.crl.pem -outform DER -out intermediate1.crl

每次你使用该CA签署证书后，都需要生成CRL。

如果你需要撤销该末端用户证书：

openssl ca -config ca.conf -revoke enduser-certs/enduser-example.com.crt -keyfile intermediate1.key -cert intermediate1.crt

样例输出：

Using configuration from ca.conf
Revoking Certificate 1000.
Data Base Updated

通过联结根证书和intermediate 1证书来创建证书链文件。

cat ../root/rootca.crt intermediate1.crt > enduser-certs/enduser-example.com.chain

发送以下文件给末端用户：

enduser-example.com.crt
enduser-example.com.key
enduser-example.com.chain

你也可以只发送给他们.crt文件，让末端用户提供他们自己的CSR。不要把它从服务器删除，否则你就不能撤销了。

合法化证书

你可以使用以下命令来针对链验证末端用户证书：

openssl verify -CAfile enduser-certs/enduser-example.com.chain enduser-certs/enduser-example.com.crt 
enduser-certs/enduser-example.com.crt: OK

你也可以针对CRL来验证。首先，将PEM、CRL和链连结：

cat ../root/rootca.crt intermediate1.crt intermediate1.crl.pem > enduser-certs/enduser-example.com.crl.chain

验证证书：

openssl verify -crl_check -CAfile enduser-certs/enduser-example.com.crl.chain enduser-certs/enduser-example.com.crt

没有撤销时的输出：

enduser-certs/enduser-example.com.crt: OK

撤销后的输出：

enduser-certs/enduser-example.com.crt: CN = example.com, ST = Noord Holland, C = NL, O = Example Inc, OU = IT Dept
error 23 at 0 depth lookup:certificate revoked
