Webb27 juli 2014 · 6. No. In the context of a hash, "bits of security" is a measure of how many possible outputs a hash function has, and thus, how hard it is to find an input with a given output. It's on a logarithmic scale, so each additional bit doubles the security. You can't compare the security of SHA-256, AES-128, and ECC-256. Webb14 okt. 2015 · The internal state is 256 bits in size for the two 32 bit variants and 512 bits in size for all four 64 bit variants. So the number of possible sizes for the internal state is less than the number of possible sizes for the final output. Going from a large internal state to a smaller output can be good or bad depending on your point of view.

WebbThis control method returns the SHA-1 or SHA-256 hash that is read out of the Management Engine extended registers during boot. The hash is exported via ACPI so the OS can verify that the ME firmware has not changed. If Management Engine is not present, or if the firmware was unable to read the extended registers, this buffer can be zero ...
