I have couple of object I serialise and store them in file between
session. If you open the files you could see the string values. I want
a way to encrypt the data so that if anyone opens the file they
shouldn't be able to read it. Just to increase the security of the
system. How can I do this?
Thanks.

DBC: Although I am not an expert, I want to offer the following advice.
If you want to encrypt the values, the best way I can think of doing
this is to write the serialization to a temporary file, then run that
file through your favorite encryption algorithm and save the encrypted
file. Have fun :)

You're right... in fact, that's what i did when i needed to create a
user database with xml. I just forgot.... sorry! That's a really good
idea, DBC, you should use rossum's advice.

Just a thought. That should not be an issue as you can read and write it as
binary data (like any binary file). So you can remove the overhead of a
base64 conversion,whic h does not really buy you anything unless you want to
pass it around in email or something.

That's another good idea. Base64 is known for its overhead, and if you
are writing to a binary file.... then you don't necessarily need b64.
