To set up SSL for a DigitalOcean droplet, you will need to obtain an SSL certificate from a Certificate Authority or generate a self-signed certificate. Once you have the certificate, you will need to install and configure it on your web server (e.g. Apache, Nginx) to enable HTTPS encryption. This typically involves updating the server configuration files to point to the SSL certificate and key file, and configuring the server to listen on the SSL port (443). Additionally, you may need to update your firewall settings to allow incoming traffic on the SSL port. Finally, you should test the SSL configuration to ensure that HTTPS is working correctly on your website.
What is a self-signed SSL certificate?
A self-signed SSL certificate is an SSL certificate that is signed by the same entity that generated it, rather than a trusted third-party Certificate Authority (CA). This means that the authenticity of the certificate cannot be verified by a well-known CA, and as a result, web browsers will typically display a warning to users that the connection may not be secure.
Self-signed SSL certificates are commonly used for testing and development purposes, as they provide encryption and security benefits for testing environments without the cost or hassle of obtaining a certificate from a trusted CA. However, they are not recommended for production use, as they are vulnerable to man-in-the-middle attacks and do not provide the same level of trust as certificates signed by a trusted CA.
What is SSL stripping?
SSL stripping is a type of cyber attack where an attacker intercepts communication between a user and a website, and downgrades the secure HTTPS connection to an unencrypted HTTP connection. This allows the attacker to see and modify the data being exchanged between the user and the website, potentially allowing them to steal sensitive information such as login credentials, credit card information, or personal details. SSL stripping is typically used in man-in-the-middle attacks on public Wi-Fi networks or other insecure connections.
What is an SSL handshake?
An SSL handshake is the process that occurs between a web browser and a server to establish a secure encrypted connection. During the handshake, the browser and the server agree on the encryption and authentication methods they will use for the session, exchange encryption keys, and verify the authenticity of each other's digital certificates. This process ensures that the data transmitted between the browser and the server is secure and cannot be intercepted or tampered with by unauthorized parties.
