What is Base64?
Base64 is a method of encoding binary data into text format. It uses 64 characters (A-Z, a-z, 0-9, +, /) to represent data.
Use Cases:
- • Email attachments (MIME)
- • Data URLs in web pages
- • API authentication tokens
- • Storing binary data in JSON/XML
Characters Used
ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/ (64 characters)= used for padding
Important Notes
- • Increases data size by approximately 33%
- • Not encryption, just encoding
- • Properly handles Unicode characters
- • Case sensitive
