Problems solved by technology

The encryption algorithm adopted by the personal data encrypted by the password manager in the prior art is simple and easily cracked by brute force; the encrypted content is stored on the user's personal computer, and once the encrypted data files are lost or modified by a virus, all of the user's data will be lost. Account information can no longer be retrieved

Embodiment 1

[0051] Embodiment one: client hardware adopts central processing unit CPU to be more than P2, internal memory more than 64M, hard disk space more than 80G, operating system is more than Microsoft Win98, and browser is IE5.0, Netscape4.0, firefox Firefox1.0 or three The higher version, the network card is more than 10M, and the bandwidth is more than 56K; the computer of the account data backup server uses: the operating system is Red Hat Enterprise Linux 4U2, Tomcat5.5 is installed, the database is MySQL5.0, 2.0G dual-core CPU, 4G memory, 100G hard disk, 100M network card, 2M bandwidth, storage device space of more than 20M; the password manager samples encrypted U disk, which can be the U228 hardware encrypted U disk flash disk produced by Netac Technology, and the flash disk has a wrong password After a certain number of times, the data can be automatically destroyed, and it can be used without installing additional software; the network communication protocol is HTTP1.0.

Embodiment 2

[0052] Embodiment 2: Application development environment parameters: Delphi2009. An account password security encryption system based on the C / S framework can be constructed.

[0053] The login unit verifies that the login password is correct, and sends the command to the decryption unit:

[0054] tmpStr:=DesDecryptStr(tmpStr);

[0055] After the decryption unit receives the decryption instruction, the decryption unit extracts and decrypts the encrypted account information data stored in the personal data unit:

[0056]

[0057] After the decryption unit decrypts the account information data, the command to send the decrypted account information data to the editing unit for editing:

[0058] gSysVariant.DataConfig.txInitXMLFromString(tmpStr);

[0059] After the editing is completed, the editing unit judges that the account information data has been modified, and sends the modified account information data to the encryption unit for encryption, and the encryption unit per...

Abstract

The invention discloses an account password secure encryption system for improving the safety of an account password. According to the technical scheme of the invention, the account password secure encryption system is characterized by comprising an account data backup server, a client and a password manager, wherein the password manager is connected to the client and the client is connected with the account data backup server via the Internet. Compared with the prior art, the account password secure encryption system has the advantages that information of an account and a password is encrypted by adopting the password manager and then saved in the password manager and a network server, thereby preventing the leakage of the account and the password when the password manage is lost; and a user can find account information of the user through the network server, thereby improving the safety of the user password.

Description

technical field [0001] The invention relates to an account security system, in particular to an encryption system for network account passwords. Background technique [0002] At present, the most commonly used application tool for managing various personal network account passwords of the public is a password manager, which can effectively save some personal account information and passwords. In the Internet era, users usually go to a website to register a user name and information, and then go to another website to register another user name and information. In the end, they can’t remember how many user names they have applied for. The password of each account, once the account password of the user is stolen, it means that all the registered accounts are stolen. The encryption algorithm adopted by the personal data encrypted by the password manager in the prior art is simple and easily cracked by brute force; the encrypted content is stored on the user's personal computer,...
