SSLtechnologie

SSL (Secure Sockets Layer) technology is a standard security protocol for establishing encrypted links between a web server and a browser in an online communication. Developed by Netscape in the mid-1990s, SSL has since been succeeded by its successor, Transport Layer Security (TLS), but the term SSL is still commonly used to refer to both the original protocol and its successor.

SSL/TLS works by using a combination of symmetric and asymmetric encryption. Asymmetric encryption is used to securely exchange a symmetric encryption key between the client and the server. Once the key is exchanged, symmetric encryption is used for the actual data transmission, which is much faster and more efficient.

SSL/TLS provides several key security features, including:

1. Data Encryption: SSL/TLS encrypts data transmitted between the client and server, preventing eavesdropping and data interception.

2. Data Integrity: SSL/TLS ensures that data is not altered during transmission, protecting against tampering.

3. Authentication: SSL/TLS can authenticate the identity of the server to the client, preventing man-in-the-middle attacks.

SSL/TLS is widely used to secure online communications, including web browsing, email, and instant messaging. It is supported by all major web browsers and is a critical component of the HTTPS protocol, which is used to secure web traffic. However, SSL/TLS is not without its vulnerabilities, and it is important to keep software up-to-date to protect against known security flaws.
