Description
Technical field
The present invention relates to a kind of encryption system more particularly to a kind of encryption systems of accounting software.
Background technique
Accounting software is used exclusively for the computer software software systems and its functional module of accounting, financial management,
Program, storing data and the relevant information of accounting and the work of pipe sun are carried out including one group of command computer.For example, accounting
Accounting processing module in software not only includes that command computer carries out the program of accounting processing, master data (accountant's department
Mesh, voucher etc.), and including the related technical data such as software service manual to instruct user of service to carry out accounting processing behaviour
Make.Accounting software usually has following major function: 1. be accounting, financial management directly provides data defeated people；2. generating
The accounting datas such as voucher, account book, report；3. a pair accounting data is converted, is exported, is analyzed, is utilized.But in the prior art, meeting
Meter software be it is important, the data of the inside are also extremely important, and confidentiality is also extremely important, and the cipher mode first having is mostly all
It is account password, cryptographic capabilities are poor, and accordingly, there exist rooms for improvement.
Summary of the invention
The object of the invention is that providing a kind of encryption system of accounting software to solve the above-mentioned problems.
The present invention through the following technical solutions to achieve the above objectives:
