What is a Base64?
Base64 is a group of similar encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. The Base64 term originates from a specific MIME content transfer encoding. Base64 encoding schemes are commonly used when there is a need to encode binary data that needs be stored and transferred over media that are designed to deal with textual data. This is to ensure that the data remains intact without modification during transport. Base64 is commonly used in a number of applications including email via MIME, and storing complex data in XML.

What is a escape?
The escape() method converts special characters (any characters that are not regular text or numbers) into hexadecimal characters, which is especially necessary for setting the values of cookies. Also useful when passing name=value pairs in the URL of a GET request, or an AJAX GET/POST request.

What is a encodeURIComponent?
encodeURIComponent escapes all characters except the following: alphabetic, decimal digits, - _ . ! ~ * ' ( ) To avoid unexpected requests to the server, you should call encodeURIComponent on any user-entered parameters that will be passed as part of a URI.

What is a encodeURI?
encodeURI replaces all characters except the following with the appropriate UTF-8 escape sequences: [; , / ? : @ & = + $ #] and [alphabetic, decimal digits, - _ . ! ~ * ' ( )]
Note that encodeURI by itself cannot form proper HTTP GET and POST requests, such as for XMLHTTPRequests, because "&", "+", and "=" are not encoded, which are treated as special characters in GET and POST requests. encodeURIComponent, however, does encode these characters. These behaviors are most likely not consistent across browsers.

What is a ROT13?
ROT13 ("rotate by 13 places", sometimes hyphenated ROT-13) is a simple substitution cipher used in online forums as a means of hiding spoilers, punchlines, puzzle solutions, and offensive materials from the casual glance. ROT13 has been described as the "Usenet equivalent of a magazine printing the answer to a quiz upside down". ROT13 is an example of the Caesar cipher, developed in ancient Rome.
