Convert id_rsa to pem file
This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. To review, open the file in an editor that reveals hidden Unicode characters.

openssl rsa -in ~/.ssh/id_rsa -outform pem > id_rsa.pem | |
chmod 600 id_rsa.pem |
Just run this
ssh-keygen -f ~/.ssh/id_rsa.pub -e -m pem > ~/.ssh/id_rsa.pub.pem
Some of the examples above contain insecure use of chmod.
In general to create a file securely, always set the umask
first! e.g.
$ rm -f examplefile ; ( umask 0077 && echo "" > examplefile ) ; ls -l examplefile
-rw------- 1 tim tim 1 Feb 26 13:55 examplefile
$ rm -f examplefile ; ( umask 0377 && echo "" > examplefile ) ; ls -l examplefile
-r-------- 1 tim tim 1 Feb 26 13:55 examplefile
...if you don't do that, then your file creation is subject to a race condition, and can be maliciously read between you creating it, and chmodding it...
Huh, TIL! Thanks @linuxtim!
