TSS_RESULT Tspi_Context_CreateObject(TSS_HCONTEXT hContext, TSS_FLAG objectType,
TSS_FLAG initFlags, TSS_HOBJECT* phObject);
TSS_Context_CreateObject creates and initializes an empty
object of the specified type and returns a handle addressing that object.
The object is bound to an already opened context hContext.
The handle of the context object.
Flag indicating the object type to create. Possible types are:
- TSS_OBJECT_TYPE_POLICY - a policy object.
- TSS_OBJECT_TYPE_ENCDATA - an encrypted data object (either sealed
or bound data).
- TSS_OBJECT_TYPE_RSAKEY - an RSA key.
- TSS_OBJECT_TYPE_PCRS - a PCR composite object.
- TSS_OBJECT_TYPE_HASH - a hash object.
Flag indicating the default attributes of the object. Attributes
for each type of object are:
- Policy:
-
TSS_POLICY_USAGE - a usage policy (for authorization to use an
object).
TSS_POLICY_MIGRATION - a migration policy.
- Encrypted data objects:
-
TSS_ENCDATA_SEAL - A data object used for a Seal operation.
TSS_ENCDATA_BIND - A data object used for a Bind operation.
TSS_ENCDATA_LEGACY - A data object for a bind operation using a
legacy key.
- RSA Keys:
-
TSS_KEY_SIZE_DEFAULT - Use the default key size of the TCS you're
connected to.
TSS_KEY_SIZE_512 - Create a 512 bit key.
TSS_KEY_SIZE_1024 - Create a 1024 bit key.
TSS_KEY_SIZE_2048 - Create a 2048 bit key.
TSS_KEY_SIZE_4096 - Create a 4096 bit key.
TSS_KEY_SIZE_8192 - Create a 8192 bit key.
TSS_KEY_SIZE_16384 - Create a 16384 bit key.
TSS_KEY_TYPE_STORAGE - Create a storage key. (Used to wrap other
keys).
TSS_KEY_TYPE_SIGNING - Create a signing key.
TSS_KEY_TYPE_BIND - Create a binding key. (Used to encrypt data).
TSS_KEY_TYPE_IDENTITY - Create an identity key. (Used for an
identity).
TSS_KEY_TYPE_LEGACY - Create a legacy key. (Can be used for signing
and binding, created from data external to a TSS).
TSS_KEY_TYPE_AUTHCHANGE - Create an ephemeral key used to change
authorization values.
TSS_KEY_VOLATILE - Create a volatile key. (Must be unloaded at
startup).
TSS_KEY_NON_VOLATILE - Create a non-volatile key. (May be unloaded
at startup).
TSS_KEY_MIGRATABLE - Create a migratable key.
TSS_KEY_NOT_MIGRATABLE - Create a non-migratable key. [DEFAULT]
TSS_KEY_AUTHORIZATION - Key will require authorization.
TSS_KEY_NO_AUTHORIZATION - Key will not require authorization.
[DEFAULT]
TSS_KEY_EMPTY_KEY - Key template which will be returned as an object
with very few attributes.
- PCR composite objects:
-
None.
- Hash objects:
-
TSS_HASH_SHA1 - a hash object of type SHA-1.
TSS_HASH_OTHER - a hash object of type other than SHA-1.
The handle of the object to be created.
Tspi_Context_CreateObject returns TSS_SUCCESS on success,
otherwise one of the following values are returned:
- TSS_E_INVALID_HANDLE - Either hContext or phObject is
an invalid handle.
- TSS_E_INTERNAL_ERROR - An error occurred internal to the
TSS.
-
Tspi_Context_CreateObject conforms to the Trusted Computing
Group Software Specification version 1.1 Golden
