Hi guys, i have reinstalled my laptop with Fedora 9.
I have my RSA private key in .ssh/id_rsa . How to generate public key
which i can use from private RSA key? (to have .ssh/id_rsa.pub).
Thanks!
ssh-keygen -t rsa -b512 -C 'a test key' -N 'junkme'
mv id_rsa.pub id_rsa.pub.orig
ssh-keygen -f id_rsa -e >SECSHpkff
ssh-keygen -i -f SECSHpkff > SECSHpkff.ossh
cat id_rsa.pub.orig ;echo " ";cat SECSHpkff.ossh
ssh-rsa

Visual diff indicates a delta in the comment portion, but otherwise the same.

So
ssh-keygen -f id_rsa -e >SECSHpkff
ssh-keygen -i -f SECSHpkff > id_rsa.pub
should get your public side back. There is probably an easier way, but this
worked.
