CAdES BES Detached Signature

See more Encryption Examples

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

    success := false

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

    crypt := chilkat.NewCrypt2()

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

    cert := chilkat.NewCert()
    success = cert.LoadPfxFile(pfxPath,pfxPassword)
    if success != true {
        fmt.Println(cert.LastErrorText())
        crypt.DisposeCrypt2()
        cert.DisposeCert()
        return
    }

    // Tell the crypt component to use this cert.
    success = crypt.SetSigningCert(cert)
    if success != true {
        fmt.Println(crypt.LastErrorText())
        crypt.DisposeCrypt2()
        cert.DisposeCert()
        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.SetCadesEnabled(true)

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

    // Create the detached CAdES-BES signature:
    success = crypt.CreateP7S(inFile,sigFile)
    if success == false {
        fmt.Println(crypt.LastErrorText())
        crypt.DisposeCrypt2()
        cert.DisposeCert()
        return
    }

    success = crypt.VerifyP7S(inFile,sigFile)
    if success == false {
        fmt.Println(crypt.LastErrorText())
        crypt.DisposeCrypt2()
        cert.DisposeCert()
        return
    }

    fmt.Println("Success!")

    crypt.DisposeCrypt2()
    cert.DisposeCert()
