An executable for any application must is "signed" before it can be executed by anyone who does not having an NX Open Author License. This section describes the signing process. This process is typically performed if an application is distributed to the user base and are used to verify that Applica tion has been developed using a valid NX Open Author license.The following steps define the general signing pr

To ensure the integrity of the document, prevent the document from being tampered with, and ensure the source of the document, the Open XML provides support for digitally signing the document. The ability to capture digital signatures by using signature lines in Office documents enables organizations to use paperless signing processes for documents such as contracts or other agreements. Unlike paper signatu

consumes CPU computing resources. RSA is currently the only algorithm that can be used for both key exchange and certificate signing. Dh:diffie-hellman key exchange algorithm, the birth time is earlier (1977), but 1999 is not public. The disadvantage is that CPU performance is more consumed. ECDHE: The DH algorithm using Elliptic curve (ECC) has the advantage of being able to achieve the same security level as RSA with a smaller prime number

If you want to test your iOS app on your iOS device, or on someone else's iOS device, or want to publish to the App Store, sign the app first. A certificate is required for signing, which requires the process of applying for a certificate.To put your own application in the device, there are several main ways:① connect the iOS device to the computer so that you can select the device in the upper left corner of Xcode, then click Run and the program will
