I only have a few minutes and can't guarantee this is complete or tested,
but maybe it will help.
All you really need is the modulus and exponent from the key. You get
these via "GetAttribData" in trousers:
tss_result = Tspi_GetAttribData(hBind_Key, TSS_TSPATTRIB_RSAKEY_INFO,
TSS_TSPATTRIB_KEYINFO_RSA_MODULUS, &m_size, &m);
tss_result = Tspi_GetAttribData(hBind_Key, TSS_TSPATTRIB_RSAKEY_INFO,
TSS_TSPATTRIB_KEYINFO_RSA_EXPONENT, &e_size, &e);
Then something like this:
RSA *rsa = RSA_new();
rsa->e = BN_bin2bn(e, e_size, rsa->e);
rsa->n = BN_bin2bn(m, m_size, rsa->n);
