Hi Aleksey,
When I verify xml document, I use xmlSecSimpleKeysMngrLoadPemCert() =
function to load cert. from a file. But this function reads cert =
information from a file. I need to get cert. information from database. =
So is there a way to use a cert. inf. which is a string in memory?=20
Aleksey I have a second question, all certificates are stored in ms =
certificate store in windows. I can obtain a certificate handle from =
this store:

HCERTSTORE m_hStore =3D CertOpenStore(CERT_STORE_PROV_SYSTEM_A,
                                        0,
                                        NULL,=20
                                        CERT_SYSTEM_STORE_SERVICES,
                                        strStoreName.c_str());

...
..

PCCERT_CONTEXT pCertContext =3D CertFindCertificateInStore(m_hStore,=20
                                                              =
X509_ASN_ENCODING | PKCS_7_ASN_ENCODING,=20
                                                                 0, =
CERT_FIND_ISSUER_ATTR, &certRDN, NULL);


Can I use this handle or any other information which is obtain from a =
win32 system in xmlsec library?

Regards,
Arda
