What are they anyway?
SSL stands for Secure Socket Layer and TLS stands for Transport Layer Security. They are bother methods/protocols that are used to encryption information that is transmitted across the internet.
Which one is better?
SSL was first implemented in 1995, which means it turned 25 in 2020. TLS is newer, more advanced, and has effectively replaced SSL.
Will TLS be replaced one day?
Some day, yes it’ll likely be replaced. But for the time being TLS is being improved as time goes on, and newer versions are coming out.
The first iterations of TLS, TLS 1.0 and TLS 1.1 are now quite old and being phased out because they’re insecure. The newer versions are 1.2, and in 2018 TLS 1.3 was released.
