如何在 ubuntu 20.04 中将 RFC4716 私钥转换为 PEM 私钥?
对于我们的项目,我们在运行最新 openssh 软件的设备上生成 ssh 密钥。 JSch 抱怨身份验证:
异常 com.jcraft.jsch.JSchException:身份验证失败
经过大量研究,包括构建一个最小的 git 客户端,我们发现其他关键文件发生了一个小变化。标题不是以
—–开始RSA私钥—–
但它开始于
——开始打开 SSH 私钥——
显示该密钥采用新的默认 RFC4716 格式进行格式化。
我在这里有同样的问题,但我想使用我的原始密钥而不是重新生成密钥。而且我不想使用像 PuTTY 这样的 GUI 应用程序。我想将其转换为脚本。
我尝试了几次尝试,但没有一个有效:
ssh-keygen -f id_rsa -m 'PEM' -e
ssh-keygen -f id_rsa -e -m pem
# I got PUBLIC KEY instead of private key
openssl rsa -in ~/.ssh/id_rsa -outform pem
openssl rsa -in id_rsa -pubout -out id_rsa.pub.pem
openssl rsa -in ~/.ssh/id_rsaunable to load Private Key
# unable to load Private Key
# 139920849113728:error:0909006C:PEM routines:get_name:no start line:../crypto/pem/pem_lib.c:745:Expecting: ANY PRIVATE KEY
我该如何转换它?
