Protection of PHP code has always been a core concern of many companies, such as well-known forums vBulletin and Discuz! PhpWind and ShopEx, which has been very popular recently, but the emergence of PHP decompilation systems has quickly caused Zend's panic and even the entire PHP user base, almost all major PHP products, including the above products, have cracked versions and even complete source code. As a result, Zend had to bow to the Cracker, acknowledge that all encryption technologies have a solution to crack, and promise to improve encryption products to provide stronger protection.
PHP encryption technology can be traced back to 01 years. at that time, PHP was very popular, so many companies wanted to launch a commercial PHP system, so PHP encryption (compilation) product came into being, then PHP dajui Zend launched its own Zend Encoder. until now, Zend's encryption products are still leaders in this field.
What about PHP decryption technology? 02 a very strong decryption system emerged at the beginning of the year. The system was actually developed by PHP core members. until now, all PHP decryption technologies have been decrypted by the technology released by PHP core members in, currently, no encryption products can be used to prevent such attacks. (Considering the interests of a huge PHP developer, we will not disclose this technology here)
It is worth mentioning that the Chinese once again have a face in the field of cracking. At the end of the 05 S, a xx studio in China called it to restore the Zend encrypted PHP code and provided online testing services. There is nothing special about this, because several similar foreign teams provided PHP cracking services in the 04 years. The difference is that the style of the XX studio is very tough. it not only spreads its own advertisements through various channels, but even uses virtual identities to publish advertisement messages on Zend's Forum, which leads to a buzz in the PHP industry.
Recently, Google's Blog users found that a Chinese user provided the PHP cracking service and also provided the free decompilation test service.
We submitted the same compiled code to several well-known foreign-established XX studios in China and PHP cracking teams that recently appeared on Google Blog, after comparing the cracked code, we found that all these cracking technologies are basically based on the same principle, but old companies have stronger strength, and the cracked code is closer to the source code, the new technical team is obviously less competent.
Later, we learned that there is actually only one XX studio in China that provides the PHP cracking service. the user on Google Blog is a Chinese member of a foreign veteran PHP cracking team, it is only recently that the Chinese community has a low profile.
Similarly, we compared the prices of cracking technologies and services of various teams. although the prices of XX studios in China are far ahead, their cracking technologies cannot be compared with those of old teams, some friends even said that the XX studio has threatened their company: if they do not pay the "protection fee", their source code will be published. It is a bit ridiculous. OPENLINK also has a large number of PHP products. it may be unknown when the studio will charge protection fees.
In fact, OPENLINK has basically specialized solutions. users can obtain all the source code at a time, so OPENLINK does not need to care about the issue of cracking, but for other brothers, we should consider the issue of intellectual property rights.
