putty - Recover an SSH private key? - Server Fault
1. @MadHatter: Private key files tend to have enough info in them to recreate the public key. (OpenSSH files do, at least, and it'd seem Putty's PPK files do too.)

How do I install an SSH private key generated by PuTTYgen?
The command for doing that is: ssh-keygen -i -f puttygen_key > openssh_key. then you can copy the contents of openssh_key in to .ssh/authorized_keys just as with a normal SSH key. The -i option is the one that tells ssh-keygen to do the conversion. The -f option tells it where to find the key to convert.
