Apr 16, 2020 · How to compute SHA256 Hash in C#. Hashing (also known as hash functions) in cryptography is a process of mapping a binary string of an arbitrary length to a small binary string of a fixed length, known as a hash value, a hash code, or a hash. Hash functions are a common way to protect secure sensitive data such as passwords and digital signatures. Some of the modern commonly-used hash

22. · Hašovací funkce je matematická funkce (resp. algoritmus) pro převod vstupních dat do (relativně) malého čísla. Výstup hašovací funkce se označuje výtah, miniatura, otisk, fingerprint či hash (česky též někdy jako haš).Hašovací funkce se používají k rychlejšímu prohledávání tabulky, porovnávání dat (například pro hledání položek v databázi, odhalování Můžete však zadat algoritmus hashování, který chcete použít, pokud potřebujete hash MD5, SHA-1 nebo jiný typ.
