Base64 Encode
Converting Data to a Human-Readable Format
What is Base64 Encoding?
Base64 encoding is a method of converting binary data into a string of ASCII characters. The term "Base64" refers to the number of characters used in the encoding scheme, which includes 64 different characters (A-Z, a-z, 0-9, and '+' and '/'). The encoding process breaks the input data into chunks of three bytes (24 bits) and represents them as four Base64 characters.
Practical Examples
Here are a couple of examples to demonstrate Base64 encoding in action:
Example 1: Encoding a String Let's say we have a string "Hello, Base64!" that we want to encode:
Original String: Hello, Base64! Base64 Encoded String: SGVsbG8sIEJhc2U2NCE=
Example 2: Encoding an Image File Suppose we have an image file "image.png" that we want to encode:
Original Image: image.png Base64 Encoded Image: iVBORw0KGg... (truncated for brevity)
