如何将SSH身份文件密钥对添加到JKS密钥库

Question

我正在构建的Java应用程序的任务之一是连接到远程SFTP服务器.为了做到这一点我有一个远程计算机的证书和本地身份(id_rsa并且id_rsa.pub将在.ssh文件夹中).这工作正常.

我想将证书和身份放在受密码保护的java密钥库中,以便更容易和更安全地配置.我有这个工作的证书,但我有问题在JKS或PKCS12密钥库中存储SSH身份(任何一个都可以工作).

为了隔离问题,我尝试了以下步骤:

我ssh-keygen -b 2048用来创建两个身份文件id_rsa_demo和id_rsa_demo.pubte本地目录.据我所知,这些是身份的私钥和公钥,所以我尝试将它们组合成一个identity.p12文件:

openssl pkcs12 -export \
               -inkey "id_rsa_demo" \
               -in "id_rsa_demo.pub" \
               -out "identity.p12" \
               -password "pass:topsecret" \
               -name "demoalias"

这给了我错误unable to load certificates.我四处搜索,似乎openssl需要一个带有-in参数完整链的证书.由于我生成的身份没有,我尝试了-nocerts选项,如下所示:

openssl pkcs12 -export \
               -inkey "id_rsa_demo" \
               -in "id_rsa_demo.pub" \
               -out "identity.p12" \
               -password "pass:topsecret" \
               -name "demoalias" \
               -nocerts

我没有得到任何错误,但该-nocerts选项符合其承诺,并且不会将我的公钥添加到pkcs12文件中:

openssl pkcs12 -info -in identity.p12

有没有办法将SSH身份存储到PKCS12或JKS密钥库中？

Answer 1

假设您有一个如下所示的私钥:

id_rsa

-----BEGIN RSA PRIVATE KEY-----

做两件事:

1)创建证书以包装密钥并将公钥公开为证书,以便keytool理解它.

openssl x509 -signkey id_rsa -req -in example.req

2)根据新请求创建自签名证书.

openssl x509 -signkey id_rsa -req -in example.req -out example.cer

然后,合并证书和私钥,然后导入keytool.

cat example.cer id_rsa > example.full
keytool -import -keystore example.jks -file example.full

这将获得钥匙.利用私钥和公钥以及与您选择的SSH/SFTP库进行交互是一项练习.
