To show only the public key in the required format, run the commmand:ĭropbearkey -y -f /etc/dropbear/dropbear_rsa_host_key | grep ssh-rsa The last command saves in /etc/dropbear/dropbear_rsa_host_key the private key, and prints the public key. To create an pair of keys, run the following command:ĭropbearkey -t rsa -f /etc/dropbear/dropbear_rsa_host_key The "dropbearkey" tool creates public and private keys or show the public key.
