In today's digital age, cyber security threats are constantly evolving, and password attacks have become increasingly prevalent. One effective method to enhance password security is through key stretching.

Key stretching is a technique used to strengthen passwords by making them more resistant to attacks like brute force and dictionary attacks. It involves repeatedly hashing a password using a cryptographic hash function, such as SHA-256, a large number of times.

By implementing key stretching, the time and computational effort required for an attacker to crack a password significantly increases. This is because each iteration of hashing adds complexity and slows down the password recovery process.

Additionally, key stretching helps mitigate the impact of password leaks and data breaches. Even if an attacker gains access to the hashed passwords, the increased computational resources needed to crack them make it a daunting task.

Overall, key stretching is an effective strategy in bolstering password security and safeguarding against various password attacks.
