kryptós I

The ancient Chinese Zhou Dynasty military classic "Liu Dao" recorded the use of cryptography, "Yin Fu", "Yin Shu" recorded the way King Wu of Zhou asked Jiang Ziya to communicate with the general during the war. Yin symbols are symbols of eight equal lengths to express different messages and instructions, which can be regarded as an alternative method in cryptography, transforming information into symbols that the enemy cannot understand. As for the Yinshu, the shifting method was used, dividing the book into three parts and passing it in three persons. Only by reassembling the three books can the restored information be obtained.
