Implement Linux kernel module providing virtual tty.

• For each line the module will produce one line containing SHA256 hash.
• Example:
  • tty input: test
  • tty output: 9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08

• build.sh

  • Run this script to build virtual tty linux kernel module.

• load.sh

  • Run this script to load(insert) virtual tty linux kernel module.
  • To check created virtual tty you can use ls /dev | grep vtty

• test.sh

  • Run this script to test virtual tty by using picocom serial port test tool.
  • When picocom is opened, input a series of chars and press enter. Vtty will sent you input value and its hashed output.

• unload.sh

  • Run this script to unload(remove) virtual tty linux kernel module.

• build_load_test.sh

  • Run this script to build,load and test virtual tty linux kernel module

First Method

./build.sh
./load.sh
./test.sh

Second Method

./build_load_test.sh

Welcome to virtual tty port!
Enter input, then press enter, you will see hashed output
To reset input values press '*'
