The struggle of PHP encryption and decryption _php Digest

But the emergence of the PHP decompile system quickly caused the Zend company and even the entire PHP user group panic, including the above products, almost all of the large PHP products have cracked version and even appeared complete source code. As a result, Zend has to bow to the cracker, acknowledging that all encryption techniques are cracked and promising to improve the encryption to provide stronger protection.

PHP encryption technology can be traced back to the 01, when PHP has been very popular, so many companies want to launch a commercial PHP system, so PHP encryption (compiler) products came into being, then the PHP big Jaw Zend Company launched its own Zend Encoder, until now, Zend's cryptographic products are still the leader in this field.

What about the PHP decryption technology? At the beginning of 02 there was a very strong decryption system. The system was actually developed by a core member of PHP, and until now, all of the PHP decryption technology has relied on the technology released by the PHP core members in 02, and there is no encryption product to avoid being cracked by the technology. (Given the benefits of a huge PHP developer, we're not exposing the technology here.)

It is worth mentioning that the Chinese again in the crack field of a face. At the end of 05, a domestic XX studio said that it can be Zend encrypted PHP code to restore, and provide online testing services. There is nothing special about this, because there are several similar teams in foreign countries that have provided PHP cracking services in 04 years. Different is the XX studio style is very tough, not only through a variety of channels to spread their own ads, even using virtual identity in the Zend Company's forum to publish advertising messages, causing a sigh of PHP industry.

Recently, in Google's blog users found a Chinese user to provide PHP cracking services, but also provide free counter-compiling testing services.

We have successively to several well-known, including foreign veteran, the domestic XX studio and recently appeared on Google blog, the PHP cracked team submitted the same compiled code, after the crack code comparison, we found that all of these cracking techniques are basically based on the same principle, Only the old company has a stronger strength, the cracked code closer to the source code, the new technical team is obviously a little less than a chip.

Later we learned that, in fact, only a XX studio in China to provide PHP cracking services, Google blog, the user is an old foreign-style PHP cracking team of Chinese members, only recently low-key appeared in the Chinese community.

In the same way, we compare the cracked technology and service price of each team, the domestic XX studio Although the price is far ahead, but its crack technology and the old team can not compare, even a friend said that the XX studio coerce their company: If you do not pay "protection fee", it is necessary to publish their source code. It really makes people a little ironic. OpenLink also has a large number of PHP products, perhaps one day to be the XX studio to collect protection fee is also unknown

In fact, OpenLink is now basically focused on the solution, users can get all the source code at once, so openlink do not need to care about the problem of cracking, but for other brother Enterprises, it is really necessary to consider the issue of intellectual property.
