encrypting/decrypting xml files

[Sam]

Hi,
I have a bunch of xml files that are used by my vb application. Those
files were written by hand (ie not generated). Do you know a tool to
encrypt them, so that no one can read their content when opening them,
which would also allow me to decrypt them in my code via some
functions?

Thx

Can someone help please ?

Hi Sam,

Take a look at System.Security.Cryptography namespace members, e.g.
DESCryptoServiceProvider.

For a sample see:

"How To Encrypt and Decrypt a File by Using Visual Basic .NET"
http://support.microsoft.com/kb/301070/

I hope this helps,
Roman

Actually in this article it is said that instead of using a key and a
IV, one should be able to use a password. That's what i want but it
doesn't work, its size should be equal or greater to a specific number
of bytes and unfortunately I don't know which value is that.
Can you help?
