About Base64 Encoding:

• Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format
• Commonly used to encode data that needs to be stored or transferred over media designed to deal with text
• Used in email attachments, embedding images in HTML/CSS, and basic authentication headers
• Increases the size of the data by about 33% (3 bytes become 4 Base64 characters)
