Being a Delphi Developer (mostly) and using SQLite quite often, I can tell you
some things about it:
You can easily wrap an SQLite DLL in Delphi, there are many free implementations of this, if you dont have one, send me a mail and I
will supply one. SEE will work as easily and I don't know of any restriction about it being used as a DLL, excepting to disguise it
for obvious reasons. (not least among which, the security of your own system).
Further to this, DISQLite works really well as a native implementation in specifically Delphi, and will work very well for your
purpose. It is however commercial so there is a cost consideration. (Yes it has a free-for-personal-use option, but any form of
commercial application needs the commercial version). The only possible disadvantage I can level at it is that to use new
adaptations of the SQLite system requires a recompile and update as opposed to just shipping another dll - but then if the dll
supports new API calls, much the same is true. If security is a concern and it is a wholly Delphi-integrated product, I would
suggest going with DISQLite if feasible.
Lastly, it seems that either you wish to use different forms of encryptions to further subterfuge or obscure database content, or
that you expect to be needing to open datasets with hitherto unknown encryptions. if it is the former, I can honestly say it is not
needed, just use whatever you like, most of the supported encryptions have ratings way above military specification when using
proper keys etc. If it is the latter case, you can't open Databases of which you don't know exactly the encryption and keys... there
is no way to do this, else the whole encryption racket would be rather useless.

but if you like I can replace it with your original SEE code for you.

Is it a pascal wrapper around SQLite or something bigger?
DISQLite3 is the only Delphi product which includes the _complete_
SQLite API, AFAIK. Using register calling conventions and the Delphi
memory manager, DISQLite3 surprised many users to perform noticeably
faster than other implementations. Features include:
etc...
