The value of data is growing every day. Data is a key factor in both scientific research and public administration. The development of IT technologies has led to the generation of a large amount of personal data, which has become the basis for the development of machine learning technologies and big data processing. This growing demand is bringing renewed interest in data privacy practices and processes. The study of the strength of a hashed message is of great importance in modern authentication systems. The hashing process is inextricably linked to the password system, since passwords are usually stored in the system not in clear text, but in the form of hashes. The SHA-256 hash function was chosen to model therainbow tables attack. An algorithm for constructing a rainbow table for the SHA-256 hash function in the Cryptool 2 environment is proposed. The conditions under which the use of rainbow tables will be effective are determined. This article aims to practically show the process of generating a password and rainbow tables to organize an attack on the SHA-256 hash function. Studies show that rainbow tables can reveal a password without salt faster than with salt. As the password bit increases, the decryption time increases in direct proportion.
