Episode notes
Hash Functions Produce Pseudo-Random Outputs
- Oshins shows SHA1's avalanche effect: tiny input changes produce totally different hashes.
- He stresses cryptographic hashes must be fast to compute but appear random to resist correlation.
Why SHA-256 Is So Hard To Break
- SHA-256 scrambles data into a fixed 64-digit code that appears random and resists brute-force guessing.
- Oshins notes it underpins Bitcoin and most secure online services.
Gigagalactic Brute-Force Thought Experiment
- Oshins walks through multiplying GPUs to show 2^256 is effectively impossible to brute force.
- He paints a gigagalactic scenario to make the scale tangible.
