Understanding Base64 Encoding
Base64 encoding is essential for handling binary data in text-based protocols. This comprehensive guide covers implementation details, use cases, and security considerations.
When to Use Base64
Base64 is perfect for encoding images in HTML/CSS, transmitting binary data in JSON, and handling file uploads in APIs. However, it's not suitable for encryption.
Performance Considerations
Base64 increases data size by approximately 33%. Understanding these performance implications is crucial for optimizing application performance.
Security Best Practices
While Base64 isn't encryption, it's often misunderstood as a security measure. Learn the proper security implications and when encryption is actually needed.
