如何获取 pem 文件的公钥？

我有一个包含我的私钥的 .pem文件，但是 BitBucket 部署密钥的格式如下:

ABAABAQDfZxX2LXOJlo5MP2tLP4fmQyjIAcATwATFKwM6K3mtT7 + LKx1jk6YlFlEcj2CFxJHHTy6LCdDqoVzL3iNcD + mDl7NbcNEHytZNJFQ5lAHPxDVa9ZbLnmP1OlfUvsQS + jAt7yMSwd8gZ6McOJfp9Zun + r5LLpjYkF + AMQFPsf + 6 lhSJaOjOTbsA39OJwlnnSO6HF3W2Om + 8 Bgdpa/E4En5RZTBwFCAvLaaXY3XgN76xCR24TwTWFicBHWeLDdADGFXB7OBOv4y805fNGbNKOl3Yb21mG89aUQlYjobeLqImyEhX36hEdMW/1I0QC///uLa + GjJouuue4WY3 Ubuntu@Box

它通常使用:

cat ~/.ssh/id_rsa.pub | pbcopy

如何以这种格式从 .pem文件提取公钥？

最佳答案

Copy the public key to clipboard.

Linux

ssh-keygen -f private.pem -y | xclip

MacOS

ssh-keygen -f private.pem -y | pbcopy

Save to file

ssh-keygen -f private.pem -y > public.pub

Note that if your permissions are vague on the .pem file, then ssh-keygen will generate an empty .pub file.

You can usually fix this with:

chmod 400 private.pem

JazzCat's answer works. small addition: if your permissions are vague on .pem file, ssh-keygen will generate empty .pub file.

if you see any complains on terminal about private key too open, try to narrow it using chmod 400 private.pem and retry above command.
