How do I SSH into rsa key?

How do I SSH into rsa key?

Procedure

1. Use the ssh-keygen tool to create a key pair.
2. Validate that the keys were generated.
3. Enable key-based authentication in the /etc/ssh directory on the SSH server.
4. Copy the rsa.
5. If you have an existing authorized_keys file, edit it to remove any no-pty restrictions.

How do I specify which SSH key to use?

To specify which private key should be used for connections to a particular remote host, use a text editor to create a ~/. ssh/config that includes the Host and IdentityFile keywords. Once you save the file, SSH will use the specified private key for future connections to that host.

Is Ecdsa better than rsa?

Compared to RSA, ECDSA has been found to be more secure against current methods of cracking thanks to its complexity. ECDSA provides the same level of security as RSA but it does so while using much shorter key lengths.

Which is better for SSH, ECDSA or RSA?

Afaict most of these systems are out of support and should probably be migrated but we all know that doesn’t happen somtimes. For example, Debian squeeze and ubuntu lucid. ECDSA has advantages in that a key can be much smaller than a RSA or DSA key for the same level of (presumed) security.

Where can I Find my RSA key pair?

Those connecting from a Windows host should skip to the Instructions (Windows) section. This will create a RSA public/private key pair in the .ssh directory below your account’s home directory. For example:

How can I force SSH to give an RSA key?

That should generate RSA public and private keys under ‘~/.ssh/id_rsa’. Now all you need to do is to copy the public key under $HOME/.ssh/authorized_keys of all those machines from which you intend to ssh to the machine on which you generated your RSA keys. And then sit back and relax!

Is it safe to use SSH key generation with DSA?

To sum up, do ssh-keygen -t rsa -b 2048 and you will be happy. As gilles says DSA is risky because if you make signatures (and using your key with a ssh client to log in is effectively making signatures) on a box with a bad RNG your key can be compromised.
