Get your binaries from here.

1.On your source host, generate a ssh key pair (private and public) : ssh-keygen

2.Copy your public key on your target host

3.Add your public key to authorized keys on your target host : cat id_rsa.pub >> .ssh/authorized_keys

And you should be done (sftp and ssh examples below).

SFTP from your source to target host using your private key : sftp –ip=192.168.1.126 –username=jeedom –privatekey=%homepath%\.ssh\id_rsa –local_filename=readme.md –command=put –debug=true

SSH from your source to target host using your private key : ssh –ip=192.168.1.126 –username=jeedom –privatekey=%homepath%\.ssh\id_rsa –debug=true

Note1 : libssh2 will accept private keys in both format (RSA PRIVATE KEY or OPENSSH PRIVATE KEY)

Note2 : libssh2 will accept public keys in OpenSSH format only (but will manage to derive the public key from the private key if you dont provide the public key)

Note3 : on linux, you can convert a public key generated by OpenSSL (in PEM format) to OpenSSH

ssh-keygen -i -m PKCS8 -f public.pem > public.pub

Note4:

You can push your public key like below:

ssh –ip=192.168.1.126 –username=jeedom –password=Mjeedom96 –put –filename=id_rsa.pub

ssh –ip=192.168.1.126 –username=jeedom –password=Mjeedom96 –delay=250 –command= »cat id_rsa.pub >> .ssh/authorized_keys »

or (pipe in)

echo « cat id_rsa.pub >> .ssh/authorized_keys » | ssh –ip=192.168.1.126 –username=jeedom –password=Mjeedom96

Note5: don’t forget to chmod 700 * in .ssh folder (and check cat /var/log/auth.log in case you get access denied)

Note6 : if still not working, check your /etc/ssh/sshd_config for the below enabled parameters

PubkeyAuthentication yes
RSAAuthentication yes
HostKeyAlgorithms +ssh-rsa
PubkeyAcceptedKeyTypes +ssh-rsa
HostbasedAcceptedKeyTypes +ssh-rsa
AuthorizedKeysFile .ssh/authorized_keys
