How to select software dongle

Software generally needs encryption and authorization , It can be done in one way , That is encryption lock . Encryption lock is used with software , The encryption lock must be inserted when opening the software , Encryption lock can realize the use of software within a time limit , LAN network lock mode , Limitations of software module functions .

Chip type

At present, the common types of encryption locks in the market are divided into single-chip microcomputer type and smart card chip . Smart card chips also include domestic smart cards and imported smart cards . Considering the current safety factors , The best choice of smart card chip for encryption lock is CC EAL 5+ Certified . This kind of smart card is almost impossible to be broken in terms of hardware .

Built in security algorithm

Encryption lock usually has a built-in security algorithm . Commonly used encryption lock algorithms are ：

• RSA1024/RSA2048
• ECC192/ECC256/ECC384
• AES128/AES192/AES256
• DES/TDES
• SHA1/SHA256

Storage space

At present, the maximum storage space of encryption lock can reach 512K.

Interface standards

USB2.0 Full speed equipment

encryption ： Shelling tools

The shelling tool can quickly encrypt and protect the code , No need to change the code , High security encryption can be completed in a few minutes .
