Yes, but this leads to corporate "contractors" and the secrets become intellectual property/trade secrets and there is nothing under the sun to FOIA those, even if that corporation has more 11 star generals than call of duty
The RNG is the backdoor always. And as said above, how you criple the entropy.
Fallacy of encryption: the algorithms are secure, it is the random numbers that are backdoored, but you cannot ever prove that. --> How? The random numbers that servers use are chosen from a list if you will as opposed to true zener diode type shit. You cannot prove this, but this is how I would do it if asked, and I am pretty sure RSA does this if not mistaken.
