The encryption dog "encryption dog" is a kind of encryption product which is inserted into the parallel port of computer and combines software and hardware (the new encryption dog also has USB port). Generally, there are dozens or hundreds of bytes of nonvolatile storage space for reading and writing, and now the newer dog also contains a single chip microcomputer.
Software developers can exchange data with softdog through interface function (that is, read and write softdog) to check whether the softdog is inserted in the interface; Or directly use the tool attached to the softdog to encrypt your own EXE file (commonly known as "shell"). In this way, software developers can set multiple software locks in the software, and use the softdog as the key to open these locks;
If the softdog is not inserted or does not correspond, the software will not run normally.
