At one point during the cancer progress process the cancer is characterized by genomic instability (high mutation rate) and extremely high metabolism(high replication rate). The immune system is actually attacking the cancer cells successfully(in generalizing here in regards to cell types), and this may lead to an optimization process where the immune system is selecting for a cancer cell able to avoid the immune defenses. This interplay creates a microenvironment which is as you described, evolutionary in nature.
As for cryptography, I would argue the biology contains hash signatures and other configurations common to cybersecurity(blockchain turns one problem into many IMO). While there may not be asymmetric cryptography, there is also no pseudorandom business.
