📚 About Base64

Base64 is a binary-to-text encoding scheme that represents binary data in ASCII string format. It's commonly used for:

• 🔐 Encoding data for URL parameters
• 📧 Email attachments (MIME)
• 🖼️ Embedding images in HTML/CSS (data URLs)
• 💾 Storing binary data in JSON/XML
• 🔧 Basic obfuscation of data

Format: Uses 64 characters (A-Z, a-z, 0-9, +, /) and = for padding.
