Using SSL

Along the same lines, if you were to determine that the contents of your Notebook are valuable, you may want to use SSL to encrypt all transmissions between your Notebook. At a minimum, then, any authentication information will be encrypted as well and this will prevent hijacking.

How to do it...

Creating an SSL certificate

You can create a certificate using openssl with this command:

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout mykey.key -out mycert.pem

Where the several options specified are as follows:

• -x509: We are using x509 protocol
• -days 365: Good for one year
• -newkey: We are generating a new key
• rsa:2048: Use the 2,048-bit RSA algorithm
• -keyout: Location to place the key
• -out: Location to place the certificate

Apply the SSL certificate

You can set the SSL certificate to be used by...
