What is Base64?
Base64 is an encoding scheme that converts binary data into ASCII text using 64 characters. It's commonly used for:
- Embedding images in HTML/CSS as
data:URIs - Encoding authentication credentials in HTTP headers

- Storing binary data in databases or URLs
Note: Base64 is encoding, not encryption. Anyone can decode it. Never use Base64 to hide sensitive data.
