The details of specific implementations are sometimes considered secret, but broadly speaking the mathematics of both projections and cryptography are extremely public. For example, GCJ-02 (the projection being obliquely referenced by the GP) is just WGS-84 + "noise". For cryptography, you can read any of the excellent textbooks and educational resources available (e.g. [0]).

i'm not supposed to say this, but my above paranoia is but a coping mechanism to deal with the harsh truth that I just cannot for the life of me completely understand any of those ideas no matter how well they're explained

It would make for a good sci fi novel, but yeah. Cryptography is cutthroat in the sense that if you’re even a little imprecise people can and will break your scheme. At some level of development the material will just filter out people from learning it.
