What is a 'hash function' used for in cybersecurity?
- Authenticating users
- Creating a digital signature
- Generating a fixed-size hash value
- Securely encrypting sensitive data
A hash function is used to generate a fixed-size hash value, commonly a digest or checksum, from input data of any size. This hash value is unique to the input data and is used for various purposes, including data integrity verification and password storage. Understanding the role of hash functions is essential for ensuring the security and integrity of data in cybersecurity applications.__________________________________________________
