Remarks

If you specify a value of XCN_AT_SIGNATURE, the KeySpec property automatically sets the KeyUsage property to XCN_NCRYPT_ALLOW_SIGNING_FLAG. If you specify XCN_AT_KEYEXCHANGE, the KeyUsage property is set to XCN_NCRYPT_ALLOW_DECRYPT_FLAG | XCN_NCRYPT_ALLOW_KEY_AGREEMENT_FLAG. The KeySpec property only applies to [legacy] providers created by using CryptoAPI.
