    en.wikipedia.org/wiki/Microsoft_Product_Activation

    In Windows 7 and later, significant hardware changes (e.g. motherboard) may require a re-activation. In Windows 10 and 11, a user can run the Activation Troubleshooter if the user has changed hardware on their device recently. If the hardware has changed again after activation, they must wait 30 days before running the troubleshooter again.

    Product Activation Requiring user to verify the license, often by entering a Product key in order to activate and use the software; some activation schemes require sending registration information over internet to prevent the same product key from being used by multiple users. In some cases, users are required to call a number to register and ...

    en.wikipedia.org/wiki/List_of_file_signatures

    A file signature is data used to identify or verify the content of a file. Such signatures are also known as magic numbers or magic bytes. Many file formats are not intended to be read as text. If such a file is accidentally viewed as a text file, its contents will be unintelligible.

    A product key is required to proceed and use Windows 95. In one form, product activation refers to a method invented by Ric Richardson and patented (U.S. patent 5,490,216) by Uniloc where a software application hashes hardware serial numbers and an ID number specific to the product's license (a product key) to

    The hardware key is programmed with a product key or other cryptographic protection mechanism and functions via an electrical connector to an external bus of the computer or appliance. [ 2 ] In software protection, dongles are two-interface security tokens with transient data flow with a pull [ clarification needed ] communication that reads ...

  9. Hash-based cryptography - Wikipedia

    en.wikipedia.org/wiki/Hash-based_cryptography

    Hash-based signature schemes use one-time signature schemes as their building block. A given one-time signing key can only be used to sign a single message securely. Indeed, signatures reveal part of the signing key. The security of (hash-based) one-time signature schemes relies exclusively on the security of an underlying hash function.
