Can Quantum Computers Break SHA-256? What Grover and BHT Really Do
Quantum computers weaken SHA-256 in a predictable, bounded way: about 128 bits of preimage security remain, and real hardware costs are far higher than the query counts suggest. Here is what Grover’s and BHT’s algorithms actually do.
