What is Cryptographic Hashing?
A cryptographic hash function takes an input and returns a fixed-size string of bytes. The output is unique to each unique input - even a small change produces a completely different hash.
Common uses include:
- Verifying file integrity (checksums)
- Password storage (with proper salting)
- Digital signatures
- Data deduplication
- Blockchain and cryptocurrencies
