Hashing Algorithm: the complete guide to understand

WebThe Secure Hash Algorithm (SHA) is the member of cryptographic hash functions. The algorithm is similar to the MD5 algorithm. However, unlike the MD5 algorithm, the SHA algorithm produces much stronger hashes. Sometimes, the hashes generated from the SHA algorithm are not always unique, which means there are chances of collision. It is essential to store passwords in a way that prevents them from being obtained by an attacker even if the application or database is … See more There are a number of modern hashing algorithms that have been specifically designed for securely storing passwords.
