I want to put a small string into the TPM2 and be able to recall it over restarts. Here is what I have tried: # put data in file that is to be sealed echo "my sealed data" > seal.dat # create a primary key tpm2_createprimary -c primary.ctx # create a child key in public and private parts tpm2_create -C primary.ctx -u obj.pub -r obj.priv # create a sealed object tpm2_create -C primary.ctx -i seal.dat -u obj.pub -r obj.priv # load the private and public portions into the TPM tpm2_load -C primary.ctx -u obj.pub -r obj.priv -c key.ctx # unseal the data tpm2_unseal -c key.ctx But after a power cycle if I run '*tpm2_unseal -c key.ctx*' I get this error: *WARNING:esys:src/tss2-esys/api/Esys_ContextLoad.c:279:Esys_ContextLoad_Finish() Received TPM Error ERROR:esys:src/tss2-esys/api/Esys_ContextLoad.c:93:Esys_ContextLoad() Esys Finish ErrorCode (0x000001df) ERROR: Esys_ContextLoad(0x1DF) - tpm:parameter(1):integrity check failed ERROR: Invalid item handle authorization ERROR: Unable to run tpm2_unseal* I am using the tpm_server (emulator) if that makes any difference. So what is the best way to load a small string into the tpm2 and be able to pull it out anytime in the future, even after power loss. Thanks
