Hi Jarkko I'm extending IMA to calculate the event data digest multiple times, for each algorithm selected by the user and supported by the TPM. You can have a look at the cover letter of the patch set: https://sourceforge.net/p/linux-ima/mailman/message/35757172/ and at the patch which calls the functions I added to the TPM driver interface: https://sourceforge.net/p/linux-ima/mailman/message/35757195/ Thanks Roberto ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ tpmdd-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/tpmdd-devel
