How to encrypt an existing file on device ...

[JustMe]

Hi ...

I've poured over all the various code snippets and samples, and it appears
that these all allow you to encrypt strings from within an application.

Is it possible to specify an existing file (ie. An Excel spreadsheet) and
encrypt it?

Thanks for your help on this ...

Hi,

..NET CF does not currently support the cryptography namespace.

This article discussing how to call Crypto API thru P-Invoke might be useful
to u.

Girish.

i dont support CryptoStream in my interface,
so you have to read the file stream into a byte[],
and then pass it to one of the ciphers.
Thanks,
