Yuav ua li cas thiaj li pab tau pob tshab ntaub ntawv encryption
- Kauj ruam 1: Tsim Database Master Key. Siv tus tswv; MUS CREATE MASTER KEY ENCRYPTION LOS NTAWM PASSWORD = 'Muab Tus Password Muaj Zog Ntawm No Rau Database Master Key'; GO.
- Kauj ruam 2: Tsim ib daim ntawv pov thawj los txhawb TDE .
- Kauj ruam 3: Tsim Database Encryption Ntsiab.
- Kauj ruam 4: Qhib TDE ntawm Database .
Ib sab ntawm no, Transparent Data Encryption yog dab tsi hauv SQL Server?
Transparent Data Encryption (TDE) encrypts SQL Server , Azure SQL ntawv Database, thiab Azure Synapse Analytics ( SQL ntawv DW) cov ntaub ntawv cov ntaub ntawv, hu ua encrypting cov ntaub ntawv thaum so. Lub DEK yog tus yuam sij symmetric ruaj ntseg los ntawm kev siv daim ntawv pov thawj khaws cia hauv tus tswv database ntawm tus server los yog tus yuam sij asymmetric tiv thaiv los ntawm EKM module.
Kuv yuav decrypt ib TDE database li cas? Cov kauj ruam hauv qab no yuav tshem tawm cov ntaub ntawv tawm ntawm TDE thiab tom qab ntawd tshem tawm cov ntaub ntawv teev tseg:
- Hloov cov ntaub ntawv kom muaj qhov kev xaiv ENCRYPTION teem rau tus nqi ntawm OFF.
- Tos kom txog thaum cov txheej txheem decryption tiav.
- Tso lub database encryption key rau lub database.
- Tshem tawm cov ntaub ntawv teev cia database.
Hauv qhov no, kuv yuav ua li cas thiaj li pab tau SQL encryption?
Qhib SQL ntawv Server Management Studio Ntawm Object Explorer toolbar, nyem Txuas, thiab tom qab ntawd nyem Database Engine. Ntawm Cov Khoom Txuas Txuas, nyem Nkag mus kev sib txuas. Nyem rau txuas.
Lub database encryption ua haujlwm li cas?
Nrog database encryption , ib encryption algorithm hloov cov ntaub ntawv hauv ib database los ntawm lub xeev nyeem tau mus rau hauv cov ntawv ciphertext ntawm cov cim tsis tau nyeem. Nrog tus yuam sij tsim los ntawm algorithm, tus neeg siv tuaj yeem decrypt cov ntaub ntawv thiab khaws cov ntaub ntawv siv tau raws li xav tau.

Kuv yuav hloov cov ntaub ntawv tab delimited rau cov ntaub ntawv csv li cas?
Mus rau cov ntawv qhia zaub mov, xaiv 'OpenCSVTab-Delimited File' (lossis tsuas yog nias Ctrl + O), thiab tom qab ntawd los ntawm lub thawv qhib, xaiv cov ntaub ntawv tab-delimited qhib. Koj tuaj yeem luam cov tab-delimited txoj hlua mus rau clipboard thiab tom qab ntawd siv 'Qhib Cov Ntawv Hauv Cov Ntawv Teev Npe' xaiv (Ctrl + F7)
Koj puas tuaj yeem ua kom kub Xovxwm pob tshab ntawv?
Nrog rau ib qho yooj yim daim ntawv thov rau cov tsoos tsho, lub Laser Transparent tshav kub daim ntawv tsim ib tug ntxiv mos thiab check luam mus rau dawb thiab lub teeb xim fabrics nrog zoo vibrancy, thiab tawm tsis muaj keeb kwm dawb nyob rau hauv lub unprinted cheeb tsam. Kev lag luam hom kub xovxwm yuav tsum tau siv nrog cov khoom no
Dab tsi yog tus lej ncaj qha uas yuav tsum raug tshem tawm ntawm cov ntaub ntawv tshawb fawb kom ua raws li kev siv cov ntaub ntawv txwv?
