48 Adding a Public Key
The key must be in RFC4716 or PEM format, with any of the following header and footer lines:
-----BEGIN PUBLIC KEY-----
-----END PUBLIC KEY-----
-----BEGIN SSH2 PUBLIC KEY-----
-----END SSH2 PUBLIC KEY-----
-----BEGIN RSA PUBLIC KEY-----
-----END RSA PUBLIC KEY-----
The following is an example of a valid entry in the sshpub.keys file in PEM format:
1,userkey,admin,active,alice
---- BEGIN SSH2 PUBLIC KEY ----

IMPORTANT!
The content of the sshaddpub.keys file must follow the same syntax as the sshpub.keys file.
RUGGEDCOM ROS allows only 16 user key entries to be stored. Each key entry must meet the following limits:
• Key type must be either RSA 2048 bits or RSA 3072 bits
• Key size must not exceed 4000 base64 encoded characters
• Entry Type in the header must not exceed 8 ASCII characters
• Access Level in the header must not exceed 8 ASCII characters (operator is maximum)
• Revocation status in the header must not exceed 8 ASCII characters (inactive is maximum)
• User Name must not exceed 12 ASCII characters
There are two ways to update sshpub.keys. Users can either upload a locally-created file directly to the
sshpub.keys file, which will replace the content in flash with the uploaded content. Or, users can upload a locally-
created file to the sshaddpub.keys file, which will keep the existing entries in the sshpub.keys file and append the
new entries.
To add keys, do the following:
1. Create a public key file via a host computer.
2. Transfer the public key file to the device using SFTP or Xmodem. For more information about transferring
files, refer to Section3.4, “Uploading/Downloading Files” .
3. Log in to the device as an admin user and access the CLI shell. For more information about accessing the CLI
shell, refer to Section2.6, “Using the Command Line Interface” .
