In the field of information security, hashing algorithms play an important role in ensuring the integrity and confidentiality of data. One of the most widely used hashing algorithms available today is the Secure Hash Algorithm (SHA-1). The hashing process in the SHA-1 algorithm consists of two main steps: initial processing of the plaintext (completing the message and dividing it into blocks), calculating the hash value. This article describes each step of the hash algorithm separately and shows how to reverse the steps to determine the plaintext from the hash value.
