SQL Server Compact Database File Security


SQL Server Compact Database File Security


 


SQL Server Compact (SQL CE) supports password protecting the database file. 


1)      Password is a must to encrypt SQL CE database


2)      When you create a SQL CE database with a password, it automatically gets encrypted


 


Now there have been many questions around on about the strength of the security.  The strength of the database file security lies in the encryption and authentication algorithms used to protect it.  Please keep your question of why authentication algorithm is required and why not just encryption algorithm sufficient enough in your mind only and I hope you agree with me on the fact that some details better be not open for the sake of better securityJ.


Now coming to what exactly are the algorithms used in what version is outlined in a table below:


 










































Version


Encryption Mode


Encryption Algorithm


Authentication Algorithm


Provider


3.0


Not Applicable


RC4


MD5


PROV_RSA_FULL MS_ENHANCED_PROV


3.1


Not Applicable


RC4


MD5


PROV_RSA_FULL MS_ENHANCED_PROV


3.5


PPC2003 Compatibility


3DES


SHA1


PROV_RSA_FULL MS_ENHANCED_PROV


3.5


Engine Default


AES128


SHA1


PROV_RSA_AES MS_ENH_RSA_AES_PROV


3.5


Platform Default


If possible use Engine Default else fall back to PPC2003 Compatibility.


4.0
