SHA256 and RIPEMD-160 are not encryption algorithms, they are hash functions. You also cannot crack encryption or pre-image HASH160 with quantum computers.
Addresses are generated from the public keys with SHA256 and RIPEMD-160, public keys are based on ECDSA and does not involve SHA256 at all. Please do some fact checking before posting. Also, it isn't very relevant to the topic.
Thanks for correcting me mate as it was my bad to add encryption word with SHA-256 and Rimped-160 hash functions.
I was also stating that private keys cannot be cracked with quantum computing also as if it was possible then German programmer would also have it done to secure his funds worth nearly 7k Bitcoins.But again it was my mistake to mix some statements.
