YouTube Description

as posted by the channel

Mary, Queen of Scots knew her captors read her official mail. So she wrote in code: she had at least 60 different ciphers. Some were so strong, code breakers in the 2020s needed a computer program to help crack them.

Once the letters were written, she sealed them using letter locking: the practice of folding and sealing paper in specific patterns so that you couldn't open it without ripping the paper.
