Delphi For PHP Serial Key Keygen

The other major attack vector is known as a software "keygen", which is much more ominous. Asits name may imply, a keygen is a form of software, often a separate program or webpage, thatgenerates valid license keys, i.e. a key-generator, or "keygen."

Delphi For PHP Serial Key Keygen


Most software vendors have some type of license keygen, which they keep secret. For example, aftera user submits a successful purchase order, part of the order process calls a key generator, whichgenerates a valid, legitimate license key for the new customer.

Depending on your key generation algorithm, a keygen like this may only be able to generate validkey for a single version of an application. But in the worst case, a bad actor can create a keygenthat generates valid license keys that work across all versions of an application, requiringa complete upheaval of the product's licensing system.

It's also worth mentioning that keygens are much more valuable to bad actors than cracks, becausea keygen can be used on the real application, vs the bad actor having to distribute a modified,cracked version of the application.

I'd recommend reading the above blog post by Brandon from 2007, with his partial serial numberverification system being written in Delphi. But if you're not into Delphi, we'll be portingthe partial key verification algorithm to Node.

With that said, let's assume the role of a business that is about to release a new application.We're going to write a keygen that we, the business, can use to generate legitimate keys forour end-users after they purchase our product.

Our PKV keygen should be a tightly kept trade secret, because with it comes the power to craftlicense keys at-will. But we'll soon realize, much to our demise, keeping a PKV keygen secretis actually not possible.

Now, a keygen for production-use may have more subkeys, or the subkeys may be arrangedor intermingled differently, but the algorithm is still going to be more or less thesame. As will the algorithm's vulnerabilities.

The gist of the verification algorithm is that we firstly check key formatting, then we'llverify the checksum is valid. Next, we'll verify the format of the seed value, which if werecall is the first 8 characters of the serial.

Well, that's doubly not good, for them. And as Murphy's Law would predict, this keygen hasjust been submitted to a popular online message board that the business has no control over.The keygen grows in popularity, sales dip, stakeholders are unhappy.

Let's reclaim our role as bad actor. Users of our keygen are claiming that it no longerworks, which is weird because it was most definitely working before. They're paying usin cryptocurrency, and even though we're a bad guy, we like to keep our customers happy.

It's simple: once we start verifying the 2nd subkey, which the bad actor will once againwrite a keygen for, and then the 3rd subkey, we'll eventually run out of subkeys.Even if we use 100 subkeys, running out is inevitable.

It means that after we've rotated through verifying each of our subkeys, in our clever attemptat combatting the keygens, we'll soon have no more recourse. Sure, we can start blacklisting seedvalues directly in our application code, but that's a fool's errand when there's somethingworse than running out of subkeys.

Well, at the end of this scenario, once all subkey parameters have been leaked, the bad actorcan fully replicate our secret keygen! (After all, we've literally given them the keys to ourcastle. It was a slow trickle, but they were patient.)

With that in mind, there's no benefit to using PKV, a licensing scheme that will eventuallyleak its secrets to any bad actor that is looking, vs. modern cryptography. It's not more secure,it's not easier to distribute, and it doesn't protect you from keygens. PKV is, by design,security through obscurity. And it should no longer be used.

After generating our keypair, we're going to want to keep those encoded keys in a safeplace. We'll use the private signing key for our keygen, and we'll use the publicverify key to verify authenticity of license keys within our application.

We've learned how legacy licensing systems, such as Partial Key Verification, canbe compromised by a bad actor, and how PKV is insecure by-design. We even wrote aPKV keygen ourselves. We then wrote a couple secure licensing systems using moderncryptography, implementing Ed25519 and RSA-2048 signature verification.

The good news is that unless a bad actor can break Ed25519 or RSA-2048, writinga keygen is effectively impossible. Besides, if a bad actor can break Ed25519 orRSA-2048 in 2021, we'll have much bigger things to worry about, anyways.

But remember, a crack != a keygen, so your application's licensing always runsthe risk of being circumvented via code modification. But license keys cannotbe forged when you utilize a licensing system built on modern cryptography.

The Installer opens the Registration dialog box during the installation of RAD Studio unless you previously install a registration file.The Offline Installer opens the Registration dialog box or the License Manager depending on whether you choose to use a serial number or you choose to use a registration file. After you register a RAD Studio license, you are taken back to the Offline Installer. If you choose to request a trial, the Offline Installer opens the Registration wizard after the installation.

The Registration wizard allows you to activate a trial version of RAD Studio or register RAD Studio using a serial number. If you need to register RAD Studio using a license file instead, use the License Manager.

Opens a dialog box where you can enter the serial number to add to the list of Unregistered serial numbers of the left-hand side column. This allows you to see the details associated with a given serial number without actually registering it on your system.

  • Key features:EXECryptor has innovative, powerful, anti-cracking, anti-debugging, anti-trace, and anti-reversing software in the business. It also has new code protection features to stop the latest cracking software and cracker issues.

  • Highly Sensitive Code Protection: EXECryptor allows developers to specify certain parts of their source code as highly sensitive areas and adds multiple layers of protection to these areas.

  • EXECryptor allows you to turn your program into trial, demo or evaluation versions easily and securely. You can set a flexible number of days or runs of your application or limit your software features.

  • EXECryptor contains an advanced flexible registration and license management system. It provides application with short, strong, serial numbers (12 characters). A serial number can be time-limited, can be locked to a Hardware ID, can contain encrypted registration information such as license type, and can allow features and other user defined information. EXECryptor also supports a black list database of 'stolen' illegal keys.

  • EXECryptor supplies you with one-touch trial technology that allows you to turn your full-feature application in 'try-before-you-buy' version in a few moments without changing your program code and even includes serial number registration support.

  • EXECryptor provides you with full-feature API to integrate in your application. The API allows you to create your own unique custom protection for your application and make it more secure.

  • In addition to protection features EXECryptor allows you to compress the code and resources of your application.

  • EXECryptor does not protect only EXE-files but also DLL and ActiveX components.

EXECryptor is able to protect software written in Delphi, C++Builder, Microsoft Visual C++, LCC, PellesC, Visual Basic, PowerBASIC, IBASIC, PureBasic. All SDK's and samples are freely available.

  • HardKey Base Features:Variable length of registration key (by example: "29UD4-3K6GH-VE5SX-ZA7EK-KDMPW" or "29QM-2YKM"). You always can select compromise before length of registration key and needed level of security. Key may contain following optional fields: Hardware ID, Expiry Date, Additional Info (any string). It allows to create temporarily operating keys and keys working only on one computer. Key always includes license type info (up to16 types). For one RegistrationName, you may generate different keys (up to2^32 - more then one million). It may be used for many licenses for one user.
