Extract a File from a .p7m (PKCS7 Signed-Data)

See more Encryption Examples

_LANGUAGE_ example to extract the original file from a .p7m (Signed-Data PKCS7 Format) The .p7m contains the signed contents of the original file. It can be verified and restored by calling VerifyP7M. Go

    success := false

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

    crypt := chilkat.NewCrypt2()

    // What is a .p7m file?

    outputFile := "/Users/chilkat/testData/pdf/sample.pdf"
    inFile := "/Users/chilkat/testData/p7m/sample.pdf.p7m"

    // Verify and restore the original file:
    success = crypt.VerifyP7M(inFile,outputFile)
    if success == false {
        fmt.Println(crypt.LastErrorText())
        crypt.DisposeCrypt2()
        return
    }

    fmt.Println("Success!")

    crypt.DisposeCrypt2()
