Thanks all. I think the second example is using the Windows inbuilt crypto API via CAPICOM - which uses pretty reasonable levels if its CAPICOM 2 (I think)... can't find any useful guides on MSDN... Will the CryptAPI support 256bit AES on a vanilla (default) install of Win98 ? If so, then this will work nicely. If not, then I can use it for OS's that support 256bit AES using this API - and look for something to work on older / not supported systems (something in the back of my mind tells me that older OS's will only support 40bit etc functions...) If anyone has info to hand I'd appreciate it. TIA :)

@Horza: Thanks for reply. That code uses the ChilkatCrypt2 component - and looking at the VB design is manipulating a crypto object from that library, so it looks like it is an ActiveX component and will need registering, which I won't have rights to do... Thanks again for your time. Appreciate it. Also, just to preempt - don't want to use the Windows crypt system as can be pretty weak on older systems. Thanks again.

Hi all :) I'd really appreciate any input with a standalone tool I am developing (my coding skills are pretty weak - using VB6). This tool needs to encrypt some text +/- files, ideally using something like AES or Twofish. The target systems may be running any flavor of Windows (95-XP) and the user will not have Admin rights, and won't be able to write to registry / modify system files / register activex components etc. Does anyone know of any (ideally open-source / freeware) commandline / console tools (or better still self-managed DLLs that don't need registering) that will take a passed string-password+/-salt and return encrypted string (and vice versa) ? Any guidance greatly appreciated. TIA :roll:
