ECC and SHA 256 vs quantum computing

[undeath]

Hashing algorithms are usually not vulnerable to quantum computer attacks. Attacks against cryptographic algorithms mostly rely on being able to solve a very small but important set of mathematical problems used in most public key systems. There's some nice overview on wikipedia.
