About Hash Functions
Hash functions are mathematical algorithms that transform data of arbitrary size into a fixed-size output. They are widely used in:
- Password storage and verification
- Data integrity checking
- Digital signatures
- File or message checksums
- Blockchain and cryptocurrency systems
Key Properties
- Deterministic: Same input always produces the same hash
- Quick computation: Hash can be calculated efficiently
- Pre-image resistance: Cannot derive input from hash
- Avalanche effect: Small input changes create very different hashes
- Collision resistance: Difficult to find two inputs with same hash
