What is Base64?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used when there's a need to encode binary data, especially when that data needs to be stored and transferred over media that are designed to deal with text.
Common Uses:
- Embedding images in HTML/CSS (data URLs)
- Encoding email attachments (MIME)
- Storing complex data in JSON
- JWT tokens for authentication
- Transferring binary data where only text is allowed
