Quantum computers will certainly impact cryptography where
there's heavy reliance on factoring primes and discrete logarithms.
I am really interested in the problem of factoring primes. Will a
quantum computer help?
Yes, see: https://en.wikipedia.org/wiki/Shor%27s_algorithm
New cryptographic algorithms are being developed which will presumably
be immune to quantum computers:
https://en.wikipedia.org/wiki/Post-quantum_cryptography
All current asymmetric cryptography in wide use today (for verifying
websites you go to are trusted, that software packages are correct, in
securing confidential information between you and your bank and e-mail
provider, e.g. in digital signature, public key encryption, and key
agreement protocols) are vulnerable. This includes not only RSA
<https://en.wikipedia.org/wiki/RSA_%28cryptosystem%29> whose security
rests on factoring primes, but also the discrete logarithm problem
which is the foundation of Diffie-Hellman
<https://en.wikipedia.org/wiki/Diffie%E2%80%93Hellman_key_exchange>
key exchange and elliptic curve cryptography
<https://en.wikipedia.org/wiki/Elliptic-curve_cryptography>.
That wasn't what Bruce was interested in.
