CAdES BES Detached Signature

See more Encryption Examples

Demonstrates how to create a CAdES BES detached signature file (.p7s). Swift

func chilkatTest() {
    var success: Bool = false

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

    let crypt = CkoCrypt2()!

    // Use a digital certificate and private key from a PFX file (.pfx or .p12).
    var pfxPath: String? = "/Users/chilkat/testData/pfx/acme.pfx"
    var pfxPassword: String? = "test123"

    let cert = CkoCert()!
    success = cert.loadPfxFile(path: pfxPath, password: pfxPassword)
    if success != true {
        print("\(cert.lastErrorText!)")
        return
    }

    // Tell the crypt component to use this cert.
    success = crypt.setSigningCert(cert: cert)
    if success != true {
        print("\(crypt.lastErrorText!)")
        return
    }

    // The CadesEnabled property applies to all methods that create PKCS7 signatures. 
    // To create a CAdES-BES signature, set this property equal to true. 
    crypt.cadesEnabled = true

    // We can sign any type of file, creating a .p7s as output:
    var inFile: String? = "/Users/chilkat/testData/pdf/sample.pdf"
    var sigFile: String? = "/Users/chilkat/testData/p7s/sample.p7s"

    // Create the detached CAdES-BES signature:
    success = crypt.createP7S(inPath: inFile, p7sPath: sigFile)
    if success == false {
        print("\(crypt.lastErrorText!)")
        return
    }

    success = crypt.verifyP7S(inFilename: inFile, p7sFilename: sigFile)
    if success == false {
        print("\(crypt.lastErrorText!)")
        return
    }

    print("Success!")
