OCR A-Level Computer Science - Understanding Hash Functions & Security

Hash Function Explorer

Try different hashing algorithms and see how they process your input. Notice how even small changes create completely different hashes!

Length Hash Algorithm

Simply returns the length of the input string. Extremely vulnerable to collisions!

Hash Result:
No hash generated yet

Hash Collision Demonstration

See how different inputs can produce the same hash value - a collision! This shows why some algorithms are unsuitable for security.

Simulated Account System

See how real systems use hashing to store passwords securely. Watch the process of account creation and login verification.
