What is the contract lock for?

Contract locks are used for data link and key management. All files on the contract lock are encrypted by SSL security protocol during the whole link transmission process (the link back to the source is also encrypted), so as to ensure that the files will not be stolen during the transmission process.

The encryption key of user data is encapsulated in a digital envelope by RSA algorithm. The digital envelope opening key is jointly obtained by the user password and the independent key subsystem. User data, encryption key and digital envelope opening key are stored in different subsystems, and finally extracted and used through user login authorization.
