Hi all,

Anyone knows how to make a key from a string.

I have a key ( string ) which I want to use for a RC4 encryption. The problem I have is to set up a key (using CryptImportKey() I guess). Once I have set up the key I can call either CryptEncrypt() or CryptDecrypt().

I am generating a small pdf file which I would like to protect from modifying

Now I have a little program in vfp that does the RC4 encryption ( rc4(rc4Key, src) ). I would prefer to use the crypto functions instead since they will be much faster.


Thanks
