EVALUATION OF THE DURABILITY OF THE SHA-1 AND SHA-2 FAMILY ALGORITHMS

This article discusses the concept of hashing. Special attention is paid to the SHA-1 algorithms and the SHA-2 family, including details of their structure and application. An analysis of the resistance parameters of these algorithms is presented, with an emphasis on comparing their resistance to collision attacks and preimage finding attacks. The reasoned conclusion about the decrease in the reliability of SHA-1 and the advantage of SHA-2 algorithms allows us to form a clear understanding of current threats and relevant solutions in the field of cryptography.
