A soft certificate is equivalent to a password. When you want to use it online, you need to verify it through this. Similar to the network password token issued by the bank in the past, something similar to a U disk. This soft certificate is to copy the program of that thing and put it on your computer, so that you can use it at any time, and you don't need to keep the network password token you used before.

According to the different storage media, it can be divided into hard certificate (media certificate) and soft certificate (file certificate). If it is stored through a hardware secure medium (such as hardware), it is called a hard certificate. What is stored as an electronic document is called a soft certificate. Soft certificates do not need digital certificate media, and can be operated on any computer, and can be used by downloading and importing.

Soft certificates mainly have the following three characteristics:

First, safety. When a user applies for a certificate, there will be two different certificates, which are used to work on the computer and verify the information interaction of the user. If the computers used are different, the user needs to re-obtain the certificate used to verify the computers used by the user, but can't make a backup, so that even if others steal the certificate, they can't obtain the user's account information, which ensures the account information.

Second, uniqueness. Digital certificates give users corresponding access rights according to their identities. If you log in to another computer, but the user has no certificate backup and can't operate, he can only view the account information. A digital certificate is like a key. The so-called "one key can only open one lock" is the embodiment of its uniqueness.

Third, convenience. Users can immediately apply for, open and use digital certificates, and can choose the corresponding digital certificate protection technology according to users' needs. Users don't need to master the encryption technology or principle, but directly carry out security protection through digital certificates, which is very convenient and efficient.
