Sold $159.99 Buy It Now or Best Offer, FREE Shipping, eBay Money Back Guarantee It's unique to the laptop being unlocked. Unless there is a keygen available, most modern implementations use a hashed value from the serial number or hard drive as the master unlock password. Um, this is how it works for PC firmware passwords as well. > with this feature, Apple HQ can give a service center the ability to clear a particular firmware password without giving them a universal backdoor (hardware or software). ![]() Most PC laptop manufacturers also disable changing the boot device or choosing a temporary boot device when a setup password is enabled. > because when a firmware password is set, a Mac requires the password to choose a different boot disk. It's so much easier to flash a backup than muck around with TFTP. Incidentally, I highly recommend investing in one of these if you're doing firmware development for routers. Maybe 5 minutes to disassemble the machine.Īs for hardware, you can flash SPI chips using a Teensy and a clip chip. As far as I know, you’ll need to take the machine apart to reflash it, plus special hardware ![]()

![]() ![]() Addition and multiplication must be commutative: so a + b = b + a and similarly for multiplication.Addition and multiplication must be associative: so a + (b + c) = (a + b) + c and similarly for multiplication. ![]() Both addition and multiplicaiton are closed over the set, so for example if a and b are in the set then so are a + b and a * b.In order to be a field the following conditions also have to be met: The elements could be numbers, or they could be something else entirely. In essence a field is a set of elements with operations defined for the elements of that set that equate to something like addition, substraction, multiplication and division. We need to define what is meant by a field. However, with elliptic curve algorithms, the equivalent key length is 512 bits, which is entirely practical.įirst of all some terminology. Keys of this size are typically not practical due to the amount of processing power that would be required, and therefore the speed of the operations. As can be seen, to get equivalent strength to a 256 bit symmetric key, a standard asymmetric algorithm would have to use an enormous key of 15360 bits. ![]() ![]() Each area of the game also contains numerous secret areas to discover, as well as hidden treasures to find. From pistols and combat knives to shotguns and SMGs, there are a slew of fun guns to engage with. Weapons are easily obtainable, and you'll get to enjoy blasting enemies with a great range of weapons.

The narrative is smartly interwoven with the levels, and it remains fresh and entertaining throughout. Besides shooting Nazis and other human enemies, players will encounter a slew of paranormal creatures and biological experiments. Overall, the story is a fun mixture of military action and sci-fi. Working for a government agency known as the Office of Secret Actions, Blazkowicz tries to learn more about the evil General Deathshed and his range of paranormal experiments. Players once again take on the role of BJ Blazkowicz, who embarks on military missions to take down the Nazi machine. Return to Castle Wolfenstein takes the same setting and tone of the original game, but amps it up in some fun ways. ![]() Taken prison and kept locked up by the Nazis, BJ breaks free and goes on a killing rampage as he escapes from the prison. Set during World War II, the game followed soldier BJ Blazkowicz. The story of Wolfenstein 3D was appropriately simple, given the time the game came out. ![]() |
