Demos
For demos, we will use the demo archive. We will a Linux system to run the demos. We download the archive using the command
wget http://elf.cs.pub.ro/cns/res/lectures/lecture-09-demo.zip </code/> and then we unpack the archive<code bash> unzip lecture-09-demo.zip
and then access the demo folder that resulted after the unpack operation
cd lecture-09-demo/
We will now pass through the demos below.
The demos show various ways of using the RSA algorithm: generating keys, encrypting a message and decrypting the message.
