Base64

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used for encoding binary data in email attachments, HTML form data, and more.

Use cases: Data transmission, embedding binary data in text, API communications

URL Encoding

URL encoding converts characters into a format that can be transmitted over the Internet. Characters like spaces, special symbols, and non-ASCII characters are replaced with % followed by two hexadecimal digits.

Use cases: Web URLs, query parameters, form submissions

HTML Entities

HTML entities are used to display reserved HTML characters and special symbols in web pages. For example, < represents the less-than symbol (<), and & represents the ampersand (&).

Use cases: Web development, displaying special characters in HTML

ROT13

ROT13 is a simple substitution cipher that replaces each letter with the letter 13 positions ahead in the alphabet. It's a special case of the Caesar cipher and is commonly used for light obfuscation.

Use cases: Simple text obfuscation, puzzles, spoilers
