What is the difference between SSL, TLS, and HTTPS?

TLS is the new name for SSL. Namely, SSL protocol got to version 3.0; TLS 1.0 is "SSL 3.1". TLS versions currently defined include TLS 1.1 and 1.2. Each new version adds a few features and modifies some internal details. We sometimes say "SSL/TLS".
HTTPS is HTTP-within-SSL/TLS. SSL (TLS) establishes a secured, bidirectional tunnel for arbitrary binary data between two hosts. HTTP is a protocol for sending requests and receiving answers, each request and answer consisting of detailed headers and (possibly) some content. HTTP is meant to run over a bidirectional tunnel for arbitrary binary data; when that tunnel is an SSL/TLS connection, then the whole is called "HTTPS".
To explain the acronyms:
"SSL" means "Secure Sockets Layer". This was coined by the inventors of the first versions of the protocol, Netscape (the company was later bought by AOL).

"TLS" means "Transport Layer Security". The name was changed to avoid any legal issues with Netscape so that the protocol could be "open and free" (and published as a RFC). It also hints at the idea that the protocol works over any bidirectional stream of bytes, not just Internet-based sockets.

"HTTPS" is supposed to mean "HyperText Transfer Protocol Secure", which is grammatically unsound. Nobody, except the terminally bored pedantic, ever uses the translation; "HTTPS" is better thought of as "HTTP with an S that means SSL". Other protocol acronyms have been built the same way, e.g. SMTPS, IMAPS, FTPS... all of them being a bare protocol that "got secured" by running it within some SSL/TLS.

Configuring Wireshark to Decrypt Data

In Wireshark click Edit>Preferences…
Select and expand Protocols, scroll down (or just type ssl) and select SSL
Click the RSA Keys List Edit… button, click New and then enter the following information;
IP Address is the IP address of the host that holds the private key used to decrypt the data and serves the certificate (i.e. the decrypting host, the server)

Port is the destination port used to communicate with the host that holds the private key used to decrypt the data and serves the certificate (i.e. the decrypting host, the server)

Protocol is the upper-layer protocol encrypted by SSL/TLS, for instance, the protocol encrypted over a HTTPS web connection is HTTP

Key File – select as necessary

Password is the passphrase used to protect the private key file, if any
