the_symmetric |
SymDefObject |
for a restricted decryption key, shall be set to a supported symmetric algorithm, key size. and mode. if the key is not a restricted decryption key, this field shall be set to TPM_ALG_NULL. |
|
the_scheme |
IAsymSchemeUnion |
If the sign attribute of the key is SET, then this shall be a valid signing scheme. NOTE If the sign parameter in curveID indicates a mandatory scheme, then this field shall have the same value. If the decrypt attribute of the key is SET, then this shall be a valid key exchange scheme or TPM_ALG_NULL. If the key is a Storage Key, then this field shall be TPM_ALG_NULL.(One of KeySchemeEcdh, KeySchemeEcmqv, SigSchemeRsassa, SigSchemeRsapss, SigSchemeEcdsa, SigSchemeEcdaa, SigSchemeSm2, SigSchemeEcschnorr, EncSchemeRsaes, EncSchemeOaep, SchemeHash, NullAsymScheme) |
|
the_curveID |
EccCurve |
ECC curve ID |
|
the_kdf |
IKdfSchemeUnion |
an optional key derivation scheme for generating a symmetric key from a Z value If the kdf parameter associated with curveID is not TPM_ALG_NULL then this is required to be NULL. NOTE There are currently no commands where this parameter has effect and, in the reference code, this field needs to be set to TPM_ALG_NULL.(One of SchemeMgf1, SchemeKdf1Sp80056a, SchemeKdf2, SchemeKdf1Sp800108, NullKdfScheme) |
