将单行RSA私钥SSH密钥转换为多行

Question

我有这些私钥已转换为等效的单行。

这些键很多。

所以我决定花一些时间来编写要转换的脚本。

这还没什么。

-----BEGIN RSA PRIVATE KEY----pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=pEdInVAbH4d0PH4= pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=pEdInVAbH4d0PH4= pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=pEdInVAbH4d0PH4= pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=pEdInVAbH4d0PH4= pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=pEdInVAbH4d0PH4= -----END RSA PRIVATE KEY-----

我正在使用echo ~/.ssh/id_rsa | tr " " "\n"

这将返回：

-----BEGIN 
RSA 
PRIVATE 
KEY----- 
pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=
pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=
pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=
pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=
pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=pEdInVAbH4d0PH4=
-----END
RSA
PRIVATE
KEY-----

我一直在尝试找出将其恢复为正确格式的最佳方法。

Answer 1

假设刚刚删除了换行符的标准RSA私钥，则将进行两次sed替换将使您回到原始格式：

sed -e "s/-----BEGIN RSA PRIVATE KEY-----/&\n/"\
    -e "s/-----END RSA PRIVATE KEY-----/\n&/"\
    -e "s/\S\{64\}/&\n/g"\
    ~/.ssh/id_rsa

标准键格式要求BEGIN和END语句位于单独的行上，并且base64编码的键必须在64列处格式化。上面的命令将带您到达那里。

Answer 2

我将解决方案调整为 ed25519 算法，以便通过 SSH 与 Gitlab 通信。谢谢@Robby！

RUN sed -i -e "s/-----BEGIN OPENSSH PRIVATE KEY-----/&\n/"\
    -e "s/-----END OPENSSH PRIVATE KEY-----/\n&/"\
    -e "s/\S\{70\}/&\n/g"\
    /root/.ssh/id_ed25519

输入

-----BEGIN OPENSSH PRIVATE KEY----- XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX== -----END OPENSSH PRIVATE 
KEY-----

输出

-----BEGIN OPENSSH PRIVATE KEY-----
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX==
-----END OPENSSH PRIVATE KEY-----

Answer 3

@robby感谢您的回答，我修改了以下对我有用的内容。

sed -e "s/-----BEGIN RSA PRIVATE KEY-----/&\n/" -e "s/\S\{64\}/&\n/g" | sed "s/^\s//g" ~/.ssh/id_rsa
