Hi Guys,

We are being audited by security agencies and would like to know soonest, the best
equivalent strength of DBISAM's overall encryption strength in terms of effective bit
strength for encrypted communication between the DBISAM Server and Client. Although it is
documented as combination of blowfish and MD5, what is the overall effectivity?

Take a look at http://en.wikipedia.org/wiki/Blowfish_%28cipher%29. With a
long enough key, you are safe. And everybody in the IT security business
will know that Blowfish is a well known and good block cipher.

MD5 is "just" a checksum/hash value function, so you don't have to send and
store passwords (which is always a very bad idea).

The encryption scheme used by Elevate is state-of-the-art. The only thing I
can't find is the key length used for Blowfish.
