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

<<does it impact performance>>

Yes.  Everything gets un-encrypted and encrypted on the fly.  You don't get something for nothing.

<<, or negate the notification re 'changed by someone else ..'?>>

 It doesn't change anything else.  All it means is that when stored on disk, the data is encrypted.  

 Locking and all other functions are the same.

OK Thanks Jeff. (I'm assuming low % impact on performance when 10 concurrent users?)

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.

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.

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,
