(2) For enterprises, the requirements for document encryption products are firstly manifested in the security of file encryption system, that is, full-text encryption and high-intensity encryption algorithms must be considered in document encryption software. Enterprise encryption requirements will change with the upgrade of applications, the change of file format and the change of application scope. This requires encryption software to flexibly set the protected file format and related applications when the application environment changes.
(3) The enterprise network environment is complex, with many applications and diversified encryption requirements. Some enterprises need mobile office, some need offline use, some need to set file permissions, and some need to set offline authorization and security management. This requires encryption software to adapt to the various encryption needs of enterprises to the greatest extent.
