What is Base64 Encoding?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's widely used in various computing applications, especially when there's a need to encode binary data for transmission over text-based protocols or to store binary data in text-based systems.

Why Use Base64 Encoding?

Safely transmit binary data over text-based protocols (e.g., email)
Store complex data structures in text formats like XML or JSON
Encode data to be included in URLs (using Base64URL variant)
Obfuscate data (Note: not suitable for security purposes)

Examples and Use Cases

1. Email Attachments

Base64 is used to encode binary files (like images) for inclusion in email bodies.

2. Data URIs

Embed small images directly in HTML or CSS using Base64-encoded data URIs.

3. API Tokens

Many APIs use Base64 encoding for authentication tokens or other sensitive data.
