What is Base64?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to encode data for safe transmission over media that are designed to deal with text.
Common Use Cases:
- Encoding binary data (images, files) for email attachments
- Embedding images directly in HTML/CSS files
- Storing complex data in cookies or URLs
- Encoding credentials for HTTP Basic Authentication
