Could I use Zendit with Microsoft 2007? That's what I and my friends mostly have.

I want to be able to send encrypted e-mails, with documents of about eight, single-spaced typed pages (usually less), as attachments, among three friends. I do not see Comcast on the supported list and I have it for my internet provider. But I do have a Yahoo account. If we all have a Yahoo account, all have Microsoft 2007 or 2010, and if we each get a free Zendit account for our home computers,
1) will it matter who is each one's internet provider, and
2) can we e-mail back and forth encrypted, including attachments?
3) if so, is it hard to save the documents, when finished, to a thumb
drive so as to be able to move it to an old computer to print it out?

Thanks so much for offering this free to regular people like us!

There's a lot of encryption software on the market. You need a File encription system, not a disk system. You should get an encryption package that encodes the file to a key, otherwise anybody that understands the algorithm could decode it. Example: Suppose the three of you read the same newspaper. You could use the first three words on a specific page as the key. Each day you read the newspaper, enter the three words and messages sent that day would decode to that sequence. The down side is every file will require a different sequence. If that's too much of a hassle, you could use the same sequence like a password for all of them.

As long as the program encodes by scrambling printable ASCII characters (ASCII 32 to 128) it will transfer and save on any system. For that reason I would create the files in NotePad. Text formatting uses the non-printable ASCII characters that could create problems. You would type the information into Notepad, save it as a text file, encode the text files and send them. The person receiving them would decode them then load them into NotePad to read them.

In the same manner, you can paste encoded printable ASCII into Outlook Express or Yahoo email message bodies and they will transfer anywhere in the Internet system.

Once you finish the project, you would still be able to load the plain text final version into document producing software and format the text to the final product.
