If this is the case, be careful because the operation is irreversible and, when a file is overwritten, the old keys can no longer be recovered.Īfter choosing the path where to save your files, you will be requested to specify an optional passphrase , through which the security level for your keys can be increased. NB If a pair of keys has been previously generated, an alert message asking whether to overwrite the existing files may be received. In case of no particular need to save the keys elsewhere, confirm by pressing Enter, otherwise, simply type the new path for the id_rsa file. If a higher level of security is needed, 4096-bit RSA keys can be generated by adding the -b flag at the end of the command.Īfter pressing the Enter key, you will be requested where to save the key pair. This type of key is secure enough for most users. Then, type the following command on your machine's terminal to create a 2048-bit RSA key pair: ssh-keygen The first thing to do is generate the key pair on the Client machine, assuming here the Client is your local PC. At the end of the guide, you will be able to authenticate on your server using encrypted keys, without entering the password every time. In this tutorial you will see how to set SSH keys on your Linux CentOS 8 server. In this type of authentication, the client generates a private key and its public key, which is installed on the server machine, in order to authenticate the client. To better improve SSH security, it is advisable to configure a type of encrypted access based on the use of RSA keys, as an alternative to password-based login. The SSH service represents the main access point to your Cloud Server and, at the same time, one of the protocols that may be more subjected to attacks than others.
