Out of curiosity, what cipher did they use? I read SHA-1 for hashed memory but I couldn't find anything regarding encrypted memory

SHA1-128 per 128B cache line on the HV only. Opt-in memory crypto on everything but DMA using RC4 by the same L2 SDRAM stack

360 and One use a keygen that works off eFuse and hardware RNG all inside L2 SDRAM each boot mapped by CPU FW decrypted ROM

Thanks a lot! I have been wondering which crypto was used for some time!
