Base85 Knowledge
What is Base85?
Base85 (also known as Ascii85) is an efficient binary-to-text encoding scheme that encodes 4 bytes into 5 printable characters, achieving approximately 80% efficiency.
Encoding Principle
Base85 uses 85 printable ASCII characters to encode data by converting 32-bit integers into 5 base-85 digits.
