Load Default Certificate from Smart Card or Token

See more Certificates Examples

Chilkat contains internal logic to examine a connected smart card or USB token, and will make decisions based on make/model to successfully interact with the hardware. When faced with a new smartcard or token, the best starting point is to call LoadFromSmartcard with an empty string argument to see what Chilkat discovers. SQL Server

    -- To let Chilkat discover what smartcard or token is connected, pass an empty string to LoadFromSmartcard.
    -- When testing in this way, it's best to have only a single smartcard or token connected to the system.

    -- For example, if a certificate was successfully loaded via LoadFromSmartcard,
    -- but then signing failed, such as w/ Pdf, XmlDSig, CAdES, etc.,
    -- then we would want to examine the LastErrorText from the call to
    -- LoadFromSmartcard to get detailed information about the card.
