Hi,

I'm using Crypto (_crypt.vcx) to generate Activation Keys. I just discovered that keys generated by 2000 are different than those made by XP (40- Vs 128-bit encryption). All the solutions I have seen require changing a registry key to force this Windows or that to use the encryption of the other. Sounds silly to me to mess with users' global encryption choice for my petty needs.

I am looking for a way to 'tell' Windows to use 40 (rsabase.dll) or 128 (rsaenh.dll) for my one call, not overall. Kinda like a parameter.

Does anyone have any experience with this?

If all fails, do you know of a free string-encryption/decryption routine? Speed does not matter. This is a crucial but very low volume feature.

Thanks

Henry
