Creating an SSH-key-pair
In this post we will show you how to create a ssh-key and how to upload it correctly to your server.
- To generate an SSH-key, enter the following command on the "home" terminal:
ssh-keygen -t rsa -b 4096
1. -t stands for type and this determines the type of key 2. -b stands for bits. This can be used to determine the length of the key.
Saving the SSH-key
Enter file in which to save the key (/home/me/.ssh/id_rsa):
Here you can select a different location and an alternative name for the file containing the private key. Just press "Enter" to accept the given suggestion.
Enter passphrase (empty for no passphrase):
Optionally, a password for the public key can be assigned here. This is always queried when the public key file is used to establish a connection.
Enter same passphrase again:
Enter the same password again. If the field is empty, simply press "Enter"
Copying the SSH-key on your server
Copy the public key to the desired server. For this the password of the server is necessary. NOTE: this will only work if the public key lays on the default location
