Understanding SSL (Secure Sockets Layer)
In the ever-evolving landscape of digital communication, the importance of secure data transmission cannot be overstated. SSL, or Secure Sockets Layer, has long been the go-to encryption protocol for ensuring the confidentiality and integrity of online transactions. Developed in the mid-1990s by Netscape, SSL has played a crucial role in protecting sensitive information, such as login credentials, financial data, and personal communications, as it travels across the internet.
TLS / SSL - The complete sequence
At its core, SSL is a cryptographic protocol that establishes a secure connection between a client (such as a web browser) and a server (such as a website). When a user initiates a connection to a website, the SSL protocol kicks in, ensuring that all data exchanged between the client and the server is encrypted and protected from prying eyes. This encryption process helps to prevent unauthorized access, eavesdropping, and data tampering, making it an essential tool in the fight against cybercrime.
Over the years, SSL has undergone several iterations, with each version introducing new security features and addressing vulnerabilities identified in the previous versions. The most recent version of SSL, known as SSL 3.0, was released in 1996 and has since been largely superseded by its successor, Transport Layer Security (TLS). While SSL 3.0 still enjoys widespread use, the emergence of more advanced encryption protocols has led to a gradual decline in its adoption, as security-conscious organizations and individuals seek out more robust solutions to protect their digital assets.
Exploring TLS (Transport Layer Security)
