Apr 11, 2019 at 12:49 comment added gog Sony got its "DRM" system cracked because of their poor implementation of the ECDSA asymmetric cryptography. The main difference between symmetric and asymmetric cryptography is that you don't need to share a single secret key between "writer" and "reader", but there is a private one and a public one (that can be shared).
