What are Hash Functions?
Hash functions take input data of any size and produce a fixed-size string of bytes, typically a digest that looks random. The same input will always generate the same hash value, but even a small change to the input will produce a completely different hash.
Common Uses
- File integrity verification
- Password storage (with proper salting)
- Digital signatures
- Data deduplication
- Checksums for downloads
Security Notes
Not all hash functions are suitable for security purposes. MD5 and SHA-1 are now considered cryptographically broken. For security-critical applications, use SHA-256 or newer algorithms.
