Hi,

I have previously used the blowfish encryption toolkit quite happily in applications using SQL Server 2005. Now I am trying to run the very same apps on a SS 2008 R2 and am getting errors. The errors generated by the xp_blowfishencrypt function are 17750 error code which I believe relates to the dlls.

Has anyone succesfully used the toolkit with 2008 R2 or had experience of solving this problem when migrating to 2008 R2.

Many Thanks

Error: 17750 is "Could not load the DLL ", you are correct.

the xp_dlls are in the Binn folder of the correct instance, right? i know you can get that error due to dependancy or file path issues, if the dlls, or any companion dlls that xp_ might call, are not together in the same Binn folder.

i'm wondering if it's a 64 bit installation calling the older 32 bit dlls that is part of the issue; i'd recommend searching for recompiled 64 bit versions of the same dlls.

--edit-- the original thread has a lot of problem solving issues similar to yours:

read thru that first!

Thanks for your response Lowell.

That sounds like it could be the problem as the new installation is 64bit and the encryption toolkit dlls are probably quite a few years old and therefore likely to be 32bit. The dlls are BTW in the Binn folder so that should be in order.

I have not seen any 64bit dlls on the encryption toolkit page (http://qa.sqlservercentral.com/articles/Security/freeencryption/1980/) so if anyone knows how I would go about getting these I would be very grateful. Is it fact possible to create 64bit dlls from the 32bit ones?

Mike C, the original author, pointed to a different thread where folks talked about not being able to use 64 bit with the originals.

cygnussolutions posted a zip file for 64 bit blowfish routines.

scroll down to the post where he attached a zip file.

Thanks so much Lowell, replaced the originals with the dlls in the zip and it worked a treat.

Appreciate your help with that one as I had read the thread previously but not put 2 and 2 together with respect to the 32/64 bit inconsistency!!

I'm glad this worked out for you!
