Question:
I want to send a symmetrically keyed encrypted email message from my VB6 program.
I would like for the recipient to be able to use standard email program like Outlook Express and when the message is selected then input the symmetrical key to view the decrypted message.
Do you see this is possible with your (Chilkat) products?
Answer:
The issue is that there is no standard to do what you are asking. Standard email programs like Outlook, Eudora, Mozilla Thunderbird, etc.
can only handle public-key encrypted emails (i.e. emails encrypted using digital certificates). Chilkat actually has a feature allowing you to symmetrically (AES) encrypt
an email, but you would only use that feature if the receiver was also using Chilkat to receive and decrypt the email.
There is nothing built-into Outlook or other programs to do symmetric encryption (where the secret key is known by both sender and receiver). Your best solution may be to send your message as a file attachment
in an AES (strong-encrypted) Zip. The recipient can then open the .zip attachment and then enter a password when unzipping.
