I have created an Excel Macro that I use to send a spreadsheet as an attachment. Because of the nature of the information contained in the spreadsheet, it needs to be encrypted. I can create the message and attach the file. How do encrypt it programatically

Thanks.

As far as I'm aware, you cannot programmatically use signature / encryption
options for security reasons. If you could, viruses could start signing
themselves with your certificate!

If you already have a preshared passphrase, you could get some VB code for
an encryption algorythm such as blowfish and then encrypt the data yourself.
