Using the program, an activist could type a message on a computer and encrypt it with a floppy disk containing the one-time pad of random numbers.

This is a cryptographic technique developed around 1917 by Gilbert Vernam and Joseph Mauborgne which uses a one-use key—the one-time pad—to encrypt and decrypt plaintext.

Russian soldiers in the Ukraine war are sending out signals in morse code on a daily basis, even though there are more high tech solutions.
