Sorry, I don't understand this letter... xmlSecMSCryptoX509DataSize is
larger than sizeof(xmlSecKeyData) but lesser then
xmlSecMSCryptoKeyDataSize so assertion fails at
src\mscrypto\certkeys.c:411.

======= src\mscrypto\certkeys.c
static int
xmlSecMSCryptoKeyDataAdoptCert(xmlSecKeyDataPtr data, PCCERT_CONTEXT pCert, xmlSecKeyDataType type) {
    xmlSecMSCryptoKeyDataCtxPtr ctx;
    HCRYPTKEY hKey = 0;

    xmlSecAssert2(xmlSecKeyDataIsValid(data), -1);
    xmlSecAssert2(xmlSecKeyDataCheckSize(data, xmlSecMSCryptoKeyDataSize), -1);
=======
The last line I've quoted causes an assertion fail.


I tried to specify xmlSecMSCryptoKeyDataX509Klass as Klass for algorithm
I support.

I create data for my algorithm using:
  data = xmlSecKeyDataCreate(xmlSecMSCryptoKeyDataX509Id);

What's my fault?

Thank you!
