It supports RSA decryption and signatures as well as ECDSA signatures.The keys used by this engine are all located underneath an ECC restricted primary storage decryption key.

If this is not the case, it needs to be set using the engine ctrl.The following sequence of commands creates an ECDSA key using the TPM, signs a data file using the TPM and validates the signature: tpm2tss-genkey -a ecdsa mykey openssl pkeyutl -engine tpm2tss -keyform engine -inkey mykey -sign -in mydata -out mysig openssl pkeyutl -engine tpm2tss -keyform engine -inkey mykey -verify -in mydata -sigfile mysig The following sequence of commands creates self signed certificate using TPM key.Openssl command sets tpm2tss as engine and generates a self signed certificate based on provided CSR configuration information. See the "Signature Algorithms" configuration file command on this page: https:// Usage of s_server with HSM-protected private keys is only supported on Open SSL 1.1.0 and newer.WARNING:esys:src/tss2-esys/esys_tcti_default.c:137:tcti_from_file() Could not load TCTI file: libtss2WARNING:esys:src/tss2-esys/esys_tcti_default.c:137:tcti_from_file() Could not load TCTI file: libtss240ac9191079e490d17b7 WARNING:esys:src/tss2-esys/esys_tcti_default.c:137:tcti_from_file() Could not load TCTI file: libtss2WARNING:esys:src/tss2-esys/esys_tcti_default.c:137:tcti_from_file() Could not load TCTI file: libtss2Note: These warnings stem from the tpm2-tss libraries and are not an issue, as long as a TPM connection is established afterwards by a different tcti.The following sequence of commands creates an RSA key using the TPM, exports the public key, encrypts a data file and decrypts it using the TPM: tpm2tss-genkey -a rsa -s 2048 mykey openssl rsa -engine tpm2tss -inform engine -in mykey -pubout -outform pem -out openssl pkeyutl -pubin -inkey -in mydata -encrypt -out mycipher openssl pkeyutl -engine tpm2tss -keyform engine -inkey mykey -decrypt -in mycipher -out mydata openssl rsa -engine tpm2tss -inform engine -in mykey -pubout -outform pem -out openssl pkeyutl -engine tpm2tss -keyform engine -inkey mykey -sign -in mydata -out mysig openssl pkeyutl -pubin -inkey -verify -in mydata -sigfile mysig must not exceed the size of the RSA key, since these operation do not perform any hashing of the input data.

Thus, the TPM2_RSA_Decrypt method is also used for signing operations which also requires decrypt capabilities to be activated for this key.

  1. The floral tribute to George Michael is no longer there but his generosity to the funding of events in Highgate Village was well recognised by locals and his presence as a member of the Highgate community is still missed.
