如何创建自己的自签名根证书和要在Java密钥库中导入的中间CA？

Question

如何创建要在Java密钥库中导入的自签名根证书和中间CA？

我们将此用于SSL和TLS，以及稍后用于基于客户端证书的CLIENT-AUTH身份验证。

使用OpenSSL和KeyTool。请帮忙。

Answer 1

只是一个旁注，任何人想要生成一个链和一些证书。精炼@ EpicPandaForce自己的答案，这里是一个脚本，它在root-ca/中创建一个根CA，在intermediate/中创建一个中间CA，三个证书到out/，每个都使用中间CA签名。

#!/bin/bash -x 

set -e 

for C in `echo root-ca intermediate`; do 

    mkdir $C 
    cd $C 
    mkdir certs crl newcerts private 
    cd .. 

    echo 1000 > $C/serial 
    touch $C/index.txt $C/index.txt.attr 

    echo ' 
[ ca ] 
default_ca = CA_default 
[ CA_default ] 
dir   = '$C' # Where everything is kept 
certs   = $dir/certs    # Where the issued certs are kept 
crl_dir  = $dir/crl    # Where the issued crl are kept 
database  = $dir/index.txt   # database index file. 
new_certs_dir = $dir/newcerts   # default place for new certs. 
certificate = $dir/cacert.pem    # The CA certificate 
serial   = $dir/serial    # The current serial number 
crl   = $dir/crl.pem    # The current CRL 
private_key = $dir/private/ca.key.pem  # The private key 
RANDFILE  = $dir/.rnd  # private random number file 
nameopt  = default_ca 
certopt  = default_ca 
policy   = policy_match 
default_days = 365 
default_md  = sha256 

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

[req] 
req_extensions = v3_req 
distinguished_name = req_distinguished_name 

[req_distinguished_name] 

[v3_req] 
basicConstraints = CA:TRUE 
' > $C/openssl.conf 
done 

openssl genrsa -out root-ca/private/ca.key 2048 
openssl req -config root-ca/openssl.conf -new -x509 -days 3650 -key root-ca/private/ca.key -sha256 -extensions v3_req -out root-ca/certs/ca.crt -subj '/CN=Root-ca' 

openssl genrsa -out intermediate/private/intermediate.key 2048 
openssl req -config intermediate/openssl.conf -sha256 -new -key intermediate/private/intermediate.key -out intermediate/certs/intermediate.csr -subj '/CN=Interm.' 
openssl ca -batch -config root-ca/openssl.conf -keyfile root-ca/private/ca.key -cert root-ca/certs/ca.crt -extensions v3_req -notext -md sha256 -in intermediate/certs/intermediate.csr -out intermediate/certs/intermediate.crt 

mkdir out 

for I in `seq 1 3` ; do 
    openssl req -new -keyout out/$I.key -out out/$I.request -days 365 -nodes -subj "/CN=$I.example.com" -newkey rsa:2048 
    openssl ca -batch -config root-ca/openssl.conf -keyfile intermediate/private/intermediate.key -cert intermediate/certs/intermediate.crt -out out/$I.crt -infiles out/$I.request 
done

根据以下指南，特别感谢Jamie Nguyen制作指南使其成为可能，谢谢！

通过以下对https://jamielinux.com/articles/2013/08/act-as-your-own-certificate-authority/指导做到以下几点：

• 将OpenSSL安装的Windows：http://slproweb.com/products/Win32OpenSSL.html

• 的bin文件夹添加到环境变量PATH

• 创建一个目录对于证书，我会打电话给cert-test

• 使用以下openssl.cfg数据为[CA_default]标签：

这

[ CA_default ] 
dir  = . # Where everything is kept 
certs  = $dir/certs    # Where the issued certs are kept 
crl_dir = $dir/crl    # Where the issued crl are kept 
database = $dir/index.txt   # database index file. 
new_certs_dir = $dir/newcerts   # default place for new certs. 

certificate = $dir/cacert.pem    # The CA certificate 
serial  = $dir/serial    # The current serial number 
crl  = $dir/crl.pem    # The current CRL 
private_key = $dir/private/ca.key.pem  # The private key 
RANDFILE = $dir/.rnd  # private random number file 

• 在cert_test创建目录：certs crl newcerts private

• 使用下面的命令创建

根CA：

openssl genrsa -aes256 -out /etc/pki/CA/private/ca.key.pem 4096 

openssl req -new -x509 -days 3650 -key /etc/pki/CA/private/ca.key.pem -sha256 -extensions v3_ca -out /etc/pki/CA/certs/ca.cert.pem 

• 创建文件夹intermediate

• 创建文件夹certs crl newcerts private

• 创建文件index.txt

• 创建文件serial，写一个数字，它像1000

• 执行以下

命令：

openssl genrsa -aes256 -out intermediate/private/intermediate.key.pem 4096 

openssl req -config intermediate/openssl.cfg -sha256 -new -key intermediate/private/intermediate.key.pem -out intermediate/certs/intermediate.csr.pem 

openssl ca -keyfile private/ca.key.pem -cert certs/ca.cert.pem -extensions v3_ca -notext -md sha256 -in intermediate/certs/intermediate.csr.pem -out intermediate/certs/intermediate.cert.pem 

• 创建

链文件：从链

cat intermediate/certs/intermediate.cert.pem certs/ca.cert.pem > intermediate/certs/ca-chain.cert.pem 

• 创建JKS文件，

keytool：

keytool -importkeystore -srckeystore ia.p12 -srcstoretype PKCS12 -destkeystore ia.jks 

keytool -import -noprompt -trustcacerts -alias test_certificate -file ia.crt -keystore ia.jks -storepass helloworld 

keytool -importcert -alias test_cert_ca -keystore "c:\Program Files\Java\jdk1.8.0\jre\lib\security\cacerts" -file ca.crt 

keytool -importcert -alias test_cert_ia -keystore "c:\Program Files\Java\jdk1.8.0\jre\lib\security\cacerts" -file ia.crt 

，你可能需要导入CA证书到ia.jks。
