What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It encodes binary data by treating it numerically and translating it into a base-64 representation. Base64 encoding is commonly used when there is a need to encode binary data that needs to be stored or transmitted over media that are designed to deal with ASCII text.
Common Use Cases
- Email attachments: MIME encoding for email binary attachments.
- Data URLs: Embedding images directly in HTML/CSS as data URIs.
- API payloads: Transmitting binary file data through JSON APIs.
- Authentication: HTTP Basic Authentication credentials encoding.
- JWT tokens: JSON Web Token header and payload encoding.
