[TrouSerS-users] Load key returns 0x00000028. Unsupported key parameters

[supraja sridhar]

Hi all,

I am trying to create a pair of keys through openssl and wrap the key using
SRK.

I wrapped the key using a parent key which in turn is wrapped by SRK. When
I load the parent key first, it returns success. When I load the actual
key(hKey), it returns unsupported key parameters.

initFlags for hKey

initFlags = TSS_KEY_TYPE_LEGACY | TSS_KEY_SIZE_2048 |
TSS_KEY_VOLATILE | TSS_KEY_AUTHORIZATION |
TSS_KEY_NOT_MIGRATABLE;

Please help,
Supraja

My generic answer to these questions is to debug with a SW TPM. The
trace will tell you exactly what parameter is wrong.
