@ryanc: I've read about hash extension attacks (which is why one should use a HMAC in many cases, just to be sure in all cases where you' want to combine a hash and a secret, or two hashes).

However, if I understand correctly, each bit in a not-broken cryptographically secure hash should, in practice, be indistinguishable from being perfectly random (50% chance of being 0).

If that is the case, why would truncating any crypto-secure-hash value lead to problems, and under which conditions?

I'm truly interested and would very much appreciate pointers to articles explaining when en why that would be the case.

James Bottomley posted new version of the #HMAC encryption patches for #TPM2: https://lore.kernel.org/linux-integrity/20231127190854.13310-1-James.Bottomley@HansenPartnership.com/T/#t

I spent some time refactoring the tpm_buf changes because they were the major glitch for me in the earlier versions, and those patches have been included now to this series, which is of course great. The series is probably rather sooner than later ready for inclusion to the mainline.

This adds up to the TPM2 sealed hard drive encryption by mitigating bus interposers by a factor. An interposer anything interface the traffic between the CPU and a discrete TPM chip (i.e. not firmware TPM).

A bus interposer can reset a TPM and replay PCR’s as the chip returns to its initial state including PCRS. To mitigate this, kernel creates HMAC session for each TPM transaction and derives session key from the so.called null hierarchy, which essentially provides a new random seed per TPM reset.

Therefore, interposer’s ability to reset TPM decreases because kernel will not be able to communicate with the TPM and that way indirectly a malicious act can be detected by far better chances than ever before.

IMHO, this fits quite nicely to the stuff that #OpenSUSE and #Ubuntu have been working on lately.

#Hashrat is a multialgorithm hash suite.

Hashrat is a command line program that recursively computes cryptographic hashes for files, piped input, or directories. Hashrat supports many hashing algorithms and output modes including #MD5, #SHA, #Whirlpool, #JH, as well as #HMAC versions thereof. Hashrat can create a list of hashed files which can be checked later to find any changes within.
