How to unzip the password protected zip archive.

Today I received TDS Certificate pdf file from IDFC Bank which was inside password protected zip folder.

I could not extract the file on Ubuntu 16.04 and also on Windows 10.

Then I tried unzip command and got the following error:
unsupported compression method 99
After googling the error I learnt that I required latest version of p7zip-full(version 16.02) whereas the available version on Ubuntu 16.04 is 9.20.

I installed the latest version as follows:
sudo add-apt-repository ppa:jonathonf/backports
sudo apt-get update
sudo apt-get install p7zip-full
If you use Windows you can get latest p7zip from this link.
