Version 2 of ssh
provides alternative encryption methods
with DSA encryption instead of the RSA keys for
Version 1. There is debate as to which is more secure. Version 2
encrypts more of the data but always uses the same Diffie-Hellman
group (perhaps being more likely then that it has been cracked).
inx$ ssh-keygen -t dsa
Generating public/private dsa key pair.
Enter file in which to save the key (/home/kayon/.ssh/id_dsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/kayon/.ssh/id_dsa.
Your public key has been saved in /home/kayon/.ssh/id_dsa.pub.
The key fingerprint is:
cc:50:d4:85:86:56:b8:8a:77:57:61:51:63:89:46:09 [email protected]
$ scp .ssh/id_dsa.pub alpine:.ssh/authorized_keys2.inx
$ ssh alpine
$ cd .ssh
$ cat authorized_keys2.inx >> authorized_keys2
Be sure the protections on the files do not permit others to access
them. In particular, ssh won't work if the
is writable by anyone other than the user.
