A hash function takes input data and produces a fixed-size digest (fingerprint) that is practically impossible to reverse.
Even a tiny change in the input produces a completely different hash, making them ideal for integrity verification, password storage, and digital signatures.
For example: SHA-256("hello") = 2cf24dba...
File integrity — verify downloads by comparing SHA-256 checksums.
Password hashing — generate bcrypt hashes for secure password storage.
Digital forensics — compute MD5/SHA hashes for evidence verification.
Data deduplication — quickly identify duplicate content using CRC or MD5.
