What is SSL

What is SSL Cryptography?

SSL Cryptography uses Public Key Cryptography which requires asymmetric keys to encrypt and decrypt messages. TLS, or Transport Layer Security, is the most modern version of SSL Cryptography, or Secure Sockets Layer encryption. TLS/SSL is a standard security technology for establishing an encrypted link between a server and a client—typically a website and a browser, or a mail server and a mail client like Microsoft Outlook.

TLS/SSL encryption secures sensitive information such as credit card numbers, social security numbers, and login credentials while in transit. To establish this secure connection, the browser and the server need a TLS/SSL certificate. The technology at work behind the scenes of TLS/SSL encryption includes asymmetric and symmetric keys. It also uses different types of algorithms such as RSA and Elliptic Curve Cryptography (ECC) that are used to create the public and private keys—which make them virtually impossible to crack.
