About Base64 Encoding
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format using a radix-64 representation.
- Uses 64 characters: A-Z, a-z, 0-9, +, /
- Padding character: = (used to make output length multiple of 4)
- Increases data size by approximately 33%
- Safe for transmission over text-based protocols
