Reading from an encrypted database

I have been asked to find out if SAS is capable of connecting to and reading from an encrypted non-SAS database if we have the encryption key.

How will you be connecting - ODBC driver for example. On the connection string I should give the options of username and password e.g. in SQL passthrough:

proc sql;

connect to oracle (user="xyz" password="zyx" schema=...);

select * from connection to oracle (....);

disconnect from oracle;

quit;

You will also need SAS/Access licensed I believe.

Are you saying that ODBC has to decrypt the data? I am new at this so forgive me if I don't understand immediately.

You'll have to clarify for me what "encrypted database" you are talking about. Normally database's have access via drivers - ODBC is one type of driver. This passes your credentials onto the database process which decrypts the information and returns it via the driver to the caller. So, its a bit like a password protected zip file, except there is another layer, you put your credentials into the driver, the driver then passes it on and returns and found information.

Thanks very much. I will look at these articles.
