Re: Asymmetric Encryption in VBA

Hi Eric

I don't want to encrypt the emails. I would like to add a dialog to call a
website. To its URL I would like to add some parameters. These parameters
should be stored on the client side (on the clients registry) and they have
to be encrypted.
I can call some cryptographic functions of the advapi32.dll but I didn't get
the clue to use my already existing public key :-(

Kindest regards,
Reto

Do you want to encrypt outgoing e-mails? There are no programming
interfaces
for encryption or digital certificates or anything similar with Outlook.

Hi everybody



I would like to encrypt a string with a public key (in Outlook), send the
encrypted data to a server and decrypt the data on the server with the
private key (an application server which isn't part of the problem now).
Unfortunately I couldn't find an example or a description to encrypt the
data with VBA and Outlook 2003 (Windows XP). There are examples for
symmetric encryption but no one that shows the asymmetric encryption. Can
somebody explain me how I can import the public key into the VBA Program
and
encrypt the data? The public key does already exist as a byte stream.



Thank you in advanced for your help.



Kindest regards,
