Encryption dog, also known as encryption lock, is a software and hardware encryption product used in computers, intelligent hardware devices, industrial computers, cloud systems and so on. Software developers manage the authorization of software through the central control dongle of Zhejiang University, prevent unauthorized use or resist the threat of piracy, and protect source code and algorithms.
The generalized dongle is a complete set of software encryption scheme. Considering the usage, economic value, cracking pressure and software use environment of different software, a complete software encryption solution is designed from the aspects of software and hardware identification, data communication, authorization management, distribution mode and physical hardware requirements.

好的软件加密解决方案要包括软件保护涉及的各个方面，如：安 全、易用、耐用、兼容性好、跨平台、丰富的授权管理功能等。而安 全则是一个木桶效应，如果仅采用软件加壳工具或仅采用API加密，或仅考虑智能卡加密狗，这些方法都存在短板，会为破解者所利用并进行攻击。原创软件企业正在夹缝中生存，除了面临国内外软件巨头的挤压之外，同时面临着盗版对软件发展的巨大冲击。并且由于软件企业的发展正由之前的软件模仿向创新、创意发展，因此软件加密已成为国内软件企业乃至硬件设备商的重中之重。
A good software encryption solution should include all aspects involved in software protection, such as security, ease of use, durability, good compatibility, cross platform, rich authorization management functions, etc. Security is a barrel effect. If only software shelling tools or API encryption are used, or only smart card dongle is considered, these methods have shortcomings and will be used and attacked by crackers. Original software enterprises are surviving in the cracks. In addition to being squeezed by software giants at home and abroad, they are also facing the great impact of piracy on software development. And because the development of software enterprises is changing from software imitation to innovation and creativity, software encryption has become the top priority of domestic software enterprises and even hardware equipment manufacturers.
The above is about the introduction of dongle. I believe everyone has a preliminary understanding. If you want to know more, please click the central control dongle website of Zhejiang University.
