Some Clarifications for Keys by Sony (will be added later)

secure_com_lib_internal_key::FactoryInit_Password -> 2EA267093B4556ED9D3BE62E115D6D59 <- unsure what this does, available in JIG and pre 1.70 PUPs/ebootroms, probably used to initialize Syscon?

random::xseed -> AB19502586A381E670D34F560EAAF31A20475903 <- in lv1ldr 3.55, maybe others

unknown key/seed -> 87746DC81CAE22812C44FC0E4F95338C <- in lv1ldr 3.55, maybe others
