Wrench Public and Private Key generation for scp
Hi,

What tool is used to generate public and private keys for SCP?

Do you have an example script that generates these keys, puts them in files and then another example script that references them from SCP?

Thanks,

Code:
ssh-keygen

Copy the contents of id_rsa.pub into the ~/.ssh/authorized_keys file on the server you want to connect to.

The procedure for generating keys for scp is the same as for generating keys for ssh.

At it's simplest, if your system has ssh-copy-id, you can just ssh-keygen, then ssh-copy-id username@host.

What do you mean, "references them from scp" ?

Generally, if a question is misinformed -it's because the questioner doesn't understand something. So to answer your question: exactly as it sounds. How does SCP use keys to connect to a foreign server? How do I use them (keys) within the context of moving files between servers (automatically).

You haven't specified which implementation of scp you're using. I will assume it's the most popular open source implementation (OpenBSD/OpenSSH).

scp uses ssh to establish the connection. Use the -i option to specify the private key file.

When I went onto my foreign server there was already a file called ~/.ssh/authorized_keys and there was another called ~/.ssh/authorized_keys2 so I made one called

~/.ssh/authorized_keys3

I'm assuming that this is how it works? I haven't connected to the foreign server yet and am still reviewing my notes on this.

You assume incorrectly (or, at least, incompletely). If you just search the manual pages for the names of files with which you are unfamiliar, you'll save a lot of time. Specifically, in this case, refer to the "AUTHORIZED_KEYS FILE FORMAT" section of the sshd man page and the "AuthorizedKeysFile" section in sshd_config.
