THE LAST OF US serial key or number

Warehouse Key

Location

Sequence

Warehouse Key is the sixth collectible artifact that is found during the chapter "The Quarantine Zone" in The Last of Us.

Description

The Warehouse Key is a silver mechanically cut key used to open a door to the warehouse portion of the docks outside of the Boston quarantine zone. It is used and protected by Robert's's henchmen to allow access to the docks.

Location

The Warehouse Key is found during the second chapter, "The Quarantine Zone", in the section "The Slums". After Joel and Tess drop through a hole in a fence to advance to the docks, two of Robert's's men appear. This is the activation scene teaching the player how to stealth kill human enemies. After killing the two men, there are two more guys inside the nearby building. Killing one of the guys will drop the key. This is required to advance through the chapter.

Generating and validating license keys is a common requirement for commercial desktop applications. This article shows a state of the art implementation in It is simple and cryptographically secure.

Scope

When you browse StackOverflow for licensing implementations, you frequently read the following warning:

No license scheme is % secure.

It is true. So, given that our task is ultimately impossible, we don't want to think about it for too long. At the same time, we want something that is reasonably safe.

This article is about registration codes that work offline. No phoning home to a license server. Even if you use a server, you likely don't want your app to stop working just because your user doesn't have internet for a brief while. To achieve this, you will need an offline way of validating licenses.

Cracks vs. keygens

There are several ways in which people can work around the copy protection in your software. The most common are cracks. These usually patch your application's executable, to trick it into believing that there is a valid license. Every desktop application can be fooled in this way. Fortunately, cracks usually only work for specific versions of an app (eg. but not ).

The worst case for software vendors are key generators. They can be used to create arbitrarily many valid serial numbers. If a keygen exists for your app, then your licensing algorithm is compromised beyond repair.

Partial key verification

To prevent keygens from working for all versions of your software, a commonly used technique is partial key verification. Under this scheme, you only use some bits to check the validity of a license key. For example, the first version of your app might only check the first character in each group of a product key:

If someone publishes a keygen for your app, then you can release a new version that checks the second character (say) for a different requirement:

This limits the potential damage of a single key generator. But it doesn't prevent other keygens from appearing for your new app version.

Key length

Historically, license keys had to be entered manually. For instance, when you bought Windows XP, you received a CD-ROM and a printed product key that you had to type in upon installation:

To make this workable, license keys had to be short and consist of simple characters such as A - Z and 0 - 9.

Nowadays, hardly anyone types in license keys by hand. When a user purchases your software, you send them an email. They either download the license key, or copy/paste it into your application. Because of this, the length of license keys has little practical relevance today.

Older articles about license verification spend a lot of brainpower on 1) encoding information in the limited-length license key, such as a maximum app version, and 2) on partial key verification. If we drop the requirement that license keys be easy to type, we can get a simpler and more secure solution.

A modern approach

At the end of the day, a license check boils down to code like the following:

Note that this even applies to more exotic solutions. For example, say your app's binary is encrypted and only valid license keys can "decrypt" it somehow. Then amounts to asking "can this key be used to decrypt the binary?".

We thus need to choose an implementation for . Fortunately, modern cryptography gives us just the right tool for this: We can use RSA signature verification to sign the licensing data with a private key, then verify the signature with an associated public key.

Below is an example in Python that uses the rsa library. Because RSA is so ubiquitous, you should be able to easily port this to another language if required.

First, create an RSA key pair on your development machine. We use bits here because it leads to shorter signatures. In practice, you probably want bits or more.

When a user purchases, generate a license key:

This prints the following:

Send this to your user. Then, in your application, check the validity of the license key as follows:

Once execution reaches the last line, you can trust that was not tampered with. This lets you include information relevant to licensing in the data, such as a maximum app version to which your user is entitled.

The above code works as-is when you type it into one interactive Python interpreter session. In practice, you will have to ship the public key with your app and decide where the user will put the license key. These are just details however. The important parts of the implementation are all here.

Caveats & Summary

Assuming you use a large enough bit size, the above implementation should be safe from key generators. It is not immune to cracking however – as mentioned above, no desktop app is. If you want to make your app even more secure, you could look at obfuscation. This makes reverse-engineering and thus circumventing your copy protection more difficult.

Which means you can render images, fub up to 8K video, manipulate photos, create real-time audio effects, or compile your next five-star app — all at lightning speed. These women exist in a violent world, set up by Naughty Dog in the original Last of Us. Who are the strange cult that have made such an ring in the footage we've seen so far. PreSonus simply bundles the additional software with ours as an extended benefit to our customers. The index for consumer goods rose 0. Will The Last of Us Part 2 run at 4k resolution. Upon completion of fee con, the transfer will be finalized. Had the new format been used this year, Justin Rose, who actually tied for fourth place, would have finished at 14 under and beaten Tiger Woods, who actually won the event by two shots. And even with context, is this the best prime to sell the film. The condensed schedule, combined with one less playoff event, has placed an added importance on players getting off to fast starts.

The lack of glue, the use of modular components, and standard Torx screws helped give the Apple TV 4K a repairability score of eight out of ten. Stops in France, Ireland and Scotland had all benefitted in recent years from geography and a relatively quiet portion of the Tour schedule, but that will change. This translates to higher frame rates for VR, real-time 3D rendering, more lifelike special effects, and gameplay at max settings.

Knowledge Base - Baker was speaking at a p ress panel - along with Nolan North - at the MCM Comic Con in Birmingham, when he revealed the news, along with usual plaudits saying how awesome the game looked. One notable addition to the app roster on the Apple TV 4K is the app, which finally arrived on the platform in early December.

The Last of Us Part 2 has teased us with beautiful, brutal, but all too brief trailers, and we're desperate for our next glimpse of Ellie. Sadly, the lack of a PlayStation Experience event this year means we'er unlikely to get a deep dive - or a release date - before So we'll have to be patient, and just keep compiling our notes and questions on our The Last of Us Part 2 wall of craziness. How does Ellie feel about the choice Joel made to save her at the end of the last game? Where is Joel, and why hasn't he appeared in any of the trailers yet? Who are the strange cult that have made such an impression in the footage we've seen so far? Until we get answers, here's everything we do know about The Last of Us Part 2. Naughty Dog has a history of delays, and it's understandable that the studio might not want to commit to a Last of Us Part 2 release date yet. Both The Last of Us and were pushed back on more than one occasion, so it seems wise that Druckmann and co. Given that we've only just seen a gameplay demo as of E3 , this one might still be a way off. Read more: The Last of Us Part 2 story will focus on Joel and Ellie. Still, that doesn't name Joel explicitly, so there's still a chance his presence will be a psychological one rather than a literal one. Naughty Dog before its big games release. We just don't yet know in what capacity. Joel's daughter, Sarah, was the driving force of the first game, and, well Seeing as the last game ended on such a wonderfully ambiguous, quasi-cliffhanger, we expect The Last of Us 2 to deal with the lie Joel told Ellie during that emotional epilogue. Whether or not Ellie bought Joel's lie is currently unknown, but what we do know is that she seems really, really angry - though not without humanity. Whatever's going on, Ellie is in an interesting place. Read more: The Last of Us Part 2 gameplay shows Ellie meting out a whole lot of bloody violence As of Sony's E3 presentation, we've now, finally, had an intensive look at some The Last of Us Part 2 gameplay. Very much taking its cues from the first game's meaty, improvisational, evasion-driven guerrilla combat, The Last of Us Part 2 looks to take a somewhat quicker, more nimble approach with Ellie as its protagonist - she can grab bottles and hurl them seamlessly at attackers without breaking a sprint, for instance, and her transitions between various types of cover and combat look a lot slicker than Joel's. That said, the level of graphic violence has clearly gone up. The Last of Us was no slouch when it came to uncomfortable gore, but the Last of Us Part 2 gameplay demo is on a whole other level. Following a tender scene of friendship and romance, we starkly cut to Ellie, knife already in a man's throat, gutting him like a fish. It only stays messy from there on out, the violence depicted as hovering somewhere between extravagantly graphic bloodletting and gritty, anatomically realistic unpleasantness. It's nasty, crunchy, choking, gurgling, and wheezing stuff throughout. Hopefully there's a reason for that. The first game was, after all, a violent game about violence, in which the unglamourous depiction of killing with repercussions formed a great deal of the point. With so little context for Ellie's actions so far, it's hard to know whether The Last of Us Part 2 is doing something clever here, or just trying to win a 'maturity' arms-race with itself. We'll probably only know for sure when we get hold of the final game. The Last of Us Part 2 trailer selection is high on mood and threat, low on context We've actually now had a few different The Last of Us Part 2 trailers, yet still, somehow, we have very little idea of what's going on. The first was an ambient piece, reintroducing Joel and Ellie while giving very little detail of the scenario. The second was a sustained, gruelling bout of violence, depicting a bunch of characters we don't know, but hinting at a far more tribalised society with at least one murderous cult in its midst. As of E3 though, we have a proper, focused look at Ellie and her story, told through both cutscene and The Last of Us Part 2 gameplay. Though you probably watched it on the way to scrolling down here. No, we're still not sure what's going on either. The original began in Boston then went on a journey across the United States as far west as Salt Lake City. When we last saw Joel and Ellie, they'd headed back east a ways to Jackson County in Wyoming, planning to stay at the settlement led by Joel's brother Tommy. We don't know how long that arrangement lasted, but Ellie's clearly done more traveling since then. It seems unlikely that The Last of Us Part 2 will remain rooted in the Pacific Northwest after how much roving the first game did. Maybe Ellie will make her way down the coast? We don't know if things are as bad on the western seaboard in terms of infection and military oppression. But it wouldn't be much of a survival story if Ellie just traipsed down to Portland and lived happily ever after. Couldn't be prouder to be a part of this! Update: Bruce Straley has since left Naughty Dog, so he definitely won't be joining back in on the company's future projects, either.

He has these passion projects he just picks and chooses. He started writing some new themes for us, and for this trailer you hear some new themes at the beginning, and a new rendition for the original theme at the end.
