SHA-256 Hash Visualization
Secure Hash Algorithm - 256 bits of cryptographic integrity
SHA-256 Hash (64 hex characters = 256 bits)

Avalanche Effect Demo
Change one character and see how the entire hash changes:
Collision Resistance
Try to find two different inputs with the same hash (virtually impossible):
SHA-256 Properties
- Deterministic: Same input always produces same output
- One-way: Cannot reverse hash to find input
- Collision resistant: Infeasible to find two inputs with same hash
- Avalanche effect: Small input change completely changes output
- Fixed output: Always 256 bits regardless of input size
SHA-256 is used in Bitcoin mining, SSL certificates, password storage, and digital signatures.
Finding a collision would require approximately 2^128 operations - more than the number of atoms in the observable universe.
