ACCESS 2010 ENCRYPTION PERFORMANCE
Hi All
does anyone have a simple answer regarding the Encrypt database option.
Specifically (and ref the ominous message re row-level locking), does it impact performance, or negate the notification re 'changed by someone else ..'?
In a multi-user environment, is encryption OK?
thank you

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
Depends on a number of factors; available CPU, amount of data, pattern of usage, etc.
It's not the type of thing that it's easy to say if it will have a large or small impact other then trying it.
The only thing you can state for certain is that it will result in less performance if it's turned on.

cheers Jim.
Jim ... did encryption change in A2010? Because in <=A2003, all it did was ... say you opened an MDB in Word ... it would be *totally unreadable* ... as I recall.
Are you saying now that it actually encrypts data ?

MX,
Not sure what you mean, Access has always had the ability to encrypt and if you did, the data was unreadable.
But yes, the encryption method was changed int he past couple of releases (Believe it was A2010) because the old method had become crackable.

I don't recall ... Encryption from with in the Access UI ... every actually encrypting data. Are you positive about that ? I assume you have tried it ?
Yes. In an un-encrypted DB, you could take Word and open the db and read the fields. Yes, there would be a lot of junk, but if you understand the structure, you can read the data.
With encryption turned on, you can't read the pages at all.

Understood. But ... if you ... say were to Encrypt a BE data db - and send it to me - and I open it with Access - is the data going to be encrypted ?

If you cant read the data with an 'external' editor e.g. Word, then it must be encrypted.
and, if you open it using the password then your 'view' is un-encrypted,
