Frequently Asked Questions
What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in ASCII format. It's commonly used to transmit data over networks that only support text, such as email or HTTP.
What is URL encoding used for?
URL encoding (percent-encoding) converts special characters into a format that can be safely transmitted in URLs. For example, spaces become %20 and & becomes %26.
How does the Caesar cipher work?
The Caesar cipher is a simple substitution cipher that shifts each letter by a fixed number of positions in the alphabet. For example, with a shift of 1, 'A' becomes 'B', 'B' becomes 'C', etc.
What is Morse code?
Morse code is a method used in telecommunication to encode text characters as sequences of dots and dashes. It was originally used for telegraphy and is still learned by amateur radio operators.
