## Using a ssh key pair

Sometimes it's irritating that you are always asked for your password while using SVN. Therefore, it can be useful to use an encrypted key-pair (public key+private key) to do the job for you.

### (1) Create the key pair by typing

ssh-keygen -t dsa


Now you are prompted for a password for the private key. You can choose an empty password, which means that you can use your private key without a password. However, if somebody steals your private key, then he can do this too...

If you decide to use a "real" password, then you also have to follow point (3) below. This must be done everytime you start a new bash!

### (2) Copy the public key to the remote system and cat it into autorized_keys:

scp ~/.ssh/id_dsa.pub user@remote-system:~/key.pub
ssh user@remote-system
cat ~/key.pub >> .ssh/authorized_keys
rm ~/key.pub


### (3) If you have chosen a "real" password for your private key:

exec ssh-agent bash

ssh-add
