Public Key Authentication With PuTTY


I run PuTTYgen

provide passphrase
generate key

save public key ssh-rsa in a file ssh-rsa.txt
save private key to myuserpprd.ppk

I log to remote server as myuser

mkdir .ssh
cd .ssh
vi authorized_keys
paste the public key

chmod 600 authorized_keys*
run putty
edit the "Private key file for authentication" to provide myuserpprd.ppk

the first login I get

"Authenticating with public key "rsa-key-20120424"
Passphrase for key "rsa-key-20120424":"
