⚠️

Base64 is an encoding scheme that converts binary data into ASCII text. It's commonly used to transmit data over media designed to handle text.

Base64 encoding converts 3 bytes of binary data into 4 ASCII characters. The result is about 33% larger than the original.

Base64 is encoding, NOT encryption. Anyone can decode it. Never use it to protect sensitive data!
