block95

🧐 Encode binary data with 9 on 11 base 95 block encoding.

This project is a response to How the Great Firewall of China Detects and Blocks Fully Encrypted Traffic, as the encoding scheme used in the project...

• Get all bytes to be printable.
• Has the ratio of total 1s among all bits fluctuates around 47.5%, if input can be considered fully random.
