He helped a friend with a cursor in cryptography, made a simple two-button gateway that encrypted and decrypted text from one text field to another, with a key from the third.

The teacher said it was shit because it was never safe. Anyone can break, even his grandson doesn’t.

I reworked the proga, added 10 buttons at the top of the previous interface, all buttons were inactive except the first, you had to press alternately on each so that everything became active. The buttons are called:
1st Creating cryptographic abstractions
2nd Generating handshake keys
Three Generating customer certificates
4 is Check the server certificate
5 is Connect to the server.
6 is Connect to database
7 is Creating data encryption keys
8 is Create the second cycle of encryption keys
9 is Create a sandbox to protect information
10 is Personalizing the surroundings

After clicking on each, a pop-up window opened with the progress bar, for a random time, from 3 to 7 seconds.

After the 10th button, the block that was originally in the previous version of the proga became active.

Prepod said this is cruel. The best job he has seen.
