Understanding Cryptographic Hash Functions
What Are Hash Functions?
- One-Way Function: Hash functions are designed to be irreversible - you cannot recover the original input from the hash
- Fixed Length: Each algorithm produces a hash of a specific length regardless of input size
- Deterministic: The same input will always produce the same hash output
- Collision Resistant: It should be extremely difficult to find two different inputs that produce the same hash
- Avalanche Effect: A small change in input produces a completely different hash output
Common Use Cases
- Password storage and verification in databases
- File integrity verification and checksums
- Digital signatures and certificates
- Blockchain and cryptocurrency transactions
- Message authentication codes (MACs)
