"- Many Centuries Ago Guild Woven!!! He opened the secret language of painting. Did the thread break out of the foundation?
Is it marriage?
No, it is a code. If the thread lies at the top, it is a unit, if at the bottom, it is zero. This is how the name of the future victim is coded..."
Next, they show a paper with a ready-made code that looks like an eight-bit encoding of the letters of the Latin alphabet. The encryption resembles something painfully familiar and in a second you realize that everything you knew about the development of high-tech before that is not true, since the MULTIVETY encryption of the guild is represented by the most genuine ASCII code.
