Howdy,

I have been using the sample code for encrypting and decrypting files. I
have no trouble using the password version to encrypt a file and decrypt it
on the same machine. But when I move the file to a different machine with a
different OS, it fails. The two OSs are W2K and CE.

So far, I have found the the hash created from the same password is
different on the two machines. I have tried forcing the same hash on both
machines but that doesn't get me anywhere either. I haven't seen the CE
side, but the KP_IV of the W2K side is all 0's.

I would try transfering the key itself, but on a different problem, I can't
get CryptGetUserKey to return a key. I am using the code from the example
but nothing comes back. I get the error that there is no key.

Are there any ideas about either of these problems?

Thanks in advance.
