Create CAdES-BES .p7m using Smart Card or USB Token

See more Digital Signatures Examples

Demonstrates how to create a CAdES BES invoice.xml.p7m using a certificate stored on a smart card or USB token.

Note: This example requires Chilkat v9.5.0.77 and at the time of this writing is restricted to the Windows operating system.

Swift

func chilkatTest() {
    var success: Bool = false

    // Note: Requires Chilkat v9.5.0.77 or greater.

    // This requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    let crypt = CkoCrypt2()!

    // Use a certificate on a smartcard or USB token.
    let cert = CkoCert()!
    // Load the certificate on the smartcard currently in the reader (or on the USB token).
    // Pass an empty string to allow Chilkat to automatically choose the CSP (Cryptographi Service Provider).
    // See Load Certificate on Smartcard for information about explicitly selecting a particular CSP.
    success = cert.load(fromSmartcard: "")
    if success != true {
        print("\(cert.lastErrorText!)")
        return
    }

    // Provide the smartcard PIN.
    // If the PIN is not explicitly provided here, the Windows OS should
    // display a dialog for the PIN.
    cert.smartCardPin = "000000"

    // Provide the certificate for signing.
    success = crypt.setSigningCert(cert: cert)
    if success != true {
        print("\(crypt.lastErrorText!)")
        return
    }

    // Indicate that SHA-256 should be used.
    crypt.hashAlgorithm = "sha256"

    // Specify the signed attributes to be included.
    // (This is what makes it CAdES-BES compliant.)
    let jsonSignedAttrs = CkoJsonObject()!
    jsonSignedAttrs.updateInt(jsonPath: "contentType", value: 1)
    jsonSignedAttrs.updateInt(jsonPath: "signingTime", value: 1)
    jsonSignedAttrs.updateInt(jsonPath: "messageDigest", value: 1)
    jsonSignedAttrs.updateInt(jsonPath: "signingCertificateV2", value: 1)
    crypt.signingAttributes = jsonSignedAttrs.emit()

    var inFile: String? = "qa_data/xml/IT01234567890_11002.xml"
    var sigFile: String? = "qa_output/IT01234567890_11002.xml.p7m"

    // Create the CAdES-BES signature, which contains the original data.
    success = crypt.createP7M(inPath: inFile, p7mPath: sigFile)
    if success == false {
        print("\(crypt.lastErrorText!)")
