RSA encryption, application authorization and MSSQL backup and restore

01.QBRSA plus decryption processing--

A. Using the RSA key generator to generate the key (E,N,D) [E,n] as the private key, [D,n] as the public key

B. Forward encryption: Encrypt with private key, decrypt with public key

C. Reverse encryption: Encrypt with public key, decrypt with private key

02. Application System Certification use: Tremoteauth

A. Client request authentication, provide an authentication file for the software (system name is the file name without EXE)

B. Software developers provide certification documents according to the content provided

C. The client registers the authentication file, then uses the client system normally;

--------------------------------------

* * Pay attention to the use of common mode, or the same system multi-point plug, will cause the account number to rob the downline;

* * After the success of the certification, the service side of the number of accounting certification, when the system is not certified or more than the number of certified on-line or more than the certification time, certification will fail

* * When the client accidentally dropped the network, the server will be in 2-3 minutes to clean up the dead chain, to ensure the normal landing of other business sites use;

* * For the client accidentally dropped the network, can be in the Tremoteauth.offline event, pop-up window alert, and exit the system;

03. Backup and restore of MSSQL in application system: Tremotebackup

A. Backup: tremotebackup.backupdatabase (Database identification, server-side backup file absolute path);

B. Restore: Tremotebackup.restoredatabase (Database identification, server-side backup file absolute path);
