How does the server check the password if it does not know it? - how hash functions work
The article discusses the essence of password management in computer systems, focusing on how servers verify user passwords without storing them in plain text. Instead, servers use hashing functions that generate unique fixed-length strings from the input data, which are the passwords. This means that even if a database is compromised, the obtained hashes cannot be easily reversed to reveal the original passwords. It also addresses security concerns and the necessity of salting to add an extra layer of protection against dictionary attacks. Users should be aware of the importance of using strong, unique passwords, which the author emphasizes by pointing out best practices for managing authentication data.
