SSL (Secure Sockets Layer)

SSL (Secure Sockets Layer) and its successor,
TLS (Transport Layer Security)

SSL, is an encryption-based(Encryption is the method by which
information is converted into secret code that hides the
information’s true meaning) Internet security protocol.

it had been first developed
by Netscape in 1995 for the aim of ensuring privacy, authentication, and data integrity in Internet communications.
SSL is that the predecessor to the fashionable TLS encryption used today.

SSL/TLS has “HTTPS” in its URL instead of “HTTP.”

How does SSL/TLS work?

  1. In order to give a high degree of privacy to any website or any webpage,.
    It encrypts data which means it converts data into secret code
    that is transmitted across the web. This means that anyone who tries to intercept this data
    will only see a unclear mix of characters that is nearly
    impossible to decrypt.

2. It initiates an authentication process called a handshake between two communicating devices to ensure that both devices are really who they claim to be, as there are
many frauds out there hungry for our important and
private information.

3. It also digitally signs data in order to provide data value,
verifying that the data is not interfered with any kind of outside
intruption of any hacker, before reaching its intended recipient.

Is SSL still up to date?

It has not been updated after its 3.0 version in 1996 and is now considered to be deprecated ( NO LONGER ADVICED TO USE ).
There are several known WEAKNESS in the protocol,
and security experts recommend discontinuing its use.

In fact, most modern web browsers like CHROME no longer support
SSL at all and is replaced by TLS.
