Encryption
-
I would like to encyrpt the contents of my program before I write them to a file. How do I go about encypting the data before I write it to a file, (at the minute I am using serialization). One limitation is that I don't want to serialize the data to a temporary file and then encrypt the file as if the unencrypted file still exists then the data is not secure. Could someone please just get me started, as I am not sure where to look as many encryption tutorials on this site encrypt and decrypt a file that already exists, I want to encrypt data in memory and write it to a file encrypted, then read the encrypted data back into the program's memory. Thanks a lot

>> then the data is not secure. secure from what? Depending on the definition of "secure" it can be almost impossible to accomplish. >> many encryption tutorials on this site encrypt and decrypt a >> file that already exists Ok but at least one of them encrypts the data in memory and then writes it to the file. So that would show you how to do it yes?

If it's sufficient to just encrypt plain text data, you could encrypt your
CStrings before writing them out and after reading them in. /ravi My new year's resolution: 2048 x 1536 Home | Articles | Freeware | Music ravib@ravib.com -

Start by reading Applied Cryptography. Otherwise you will miss something subtile about encryption and get no benifit.
