StrongBit technology is a SoftComplete Development division, specialized on software protection tools development and cryptography researches.
EXECryptor - is a powerful tool used for an application code protection from reverse engineering, analysis and modifications, based on a brand new metamorphing code tranformation technology, that allows to significantly increase software security. With EXECryptor the code block to protect is disassembling and becomes a subject of nondeterminate transformations, which destroys the visible logical code structure. After the code transformation it remains executable and working as it is supposed to but it cannot be neither analysed nor modificated. There is no concept of the code decryption with EXECryptor unlike the others. Protected code blocks are always in the executable state and they are executed as a transformed code. Code restoration becomes an NP-hard problem.
EXECryptor has the innovative very powerful antidebug, antitrace and import protection features. EXECryptor allows to work with the short registration keys of 12/16 characters long. It is based on new generation of HardKey algorithm - cryptographically strong ultrashort digital signature. Algorithm is based on NP-hard problem of finding solution of low degree equation system in Galua field. The algorithm has good resistance and allows to get digital signature 60bits long. In addition to advanced protection features EXECryptor allows to compress code and resources of your application.
Also our company has developed "HardKey" algorithm - cryptography strong short digital signature. Algorithm is based on NP-hard problem of finding solution of low degree equation system in Galua field. The algorithm has more then 2^64 resistance and allows to get short digital signature 75-125 bits length. The algorithm uses such keys: public and private. Public key is necessary for signature checking, and private key is uses for creature. The algorithm guarantees the impossible private key restoration by known public key. The management of the license system of "HardKey License Manager" was realised on algorithm "HardKey" basis, that is supporting the functioning with strong short serial numbers 15-25 symbols length (by example like "29UD4-3K6GH-VE5SX"). The professional version of "HardKey License Manager" also gives the additional opportunities for serial number management: registration database, email templates and parsers, external serial number generator. "HardKey License Manager" can be used with such general programming languages as Borland Delphi, Borland C++ Builder, Microsoft Visual C++.
The "HardKey" algorithm was licensed for using in online product activation WebMoney Software Activation Service systems. License enforcement using the product activation technique ensures that each license product is used in compliance with its licensing terms. When installed on a new PC, a product starts the Activation Wizard that (with the user's permission) queries a centralized license server via the Internet, asking for permission to run. The license server then either grants or denies permission according to the software licenses owned by the end-user. In case a permission is granted, the product receives a unique Activation Code that can be used to verify the product's activation status.
