Base64 Encoding: The Bridge Between Binary and Text
In web development, we often need to transport binary data (like images or encrypted keys) through systems that only understand text (like JSON or HTML). Base64 is the universal bridge that makes this possible.
How Base64 Works
Base64 works by taking groups of 3 bytes (binary) and representing them as 4 characters from a set of 64 standard characters (A-Z, a-z, 0-9, +, /). This ensures that the data can be safely transmitted through any network or protocol without being garbled or misinterpreted.
Top Use Cases for Developers:
- Data URIs: Embedding small icons or images directly into your CSS or HTML to reduce HTTP requests.
- Basic Auth: Standardized encoding for simple username/password headers.
- JWT Payloads: Web tokens use Base64 to transport JSON objects securely as part of a URL.
⚠️ Important Note
Base64 is NOT encryption. It is merely a format. Anyone can decode a Base64 string in seconds. Never use it to hide secrets; only use it to transport data.
