I am currently sending an email from my xcode/iphone app. The requirements are to send an encrypted email or attached file and then be able to decrypt/open the information after receipient delivery.
Has anyone seen any code to help me accomplish this task?
Thanks
Leland
I don’t think you’ve quite thought this one through. In general, if an email client or webmail system does not have a feature to send an encrypted email (in any way), then you can be pretty sure that it also does not have a feature to read encrypted emails. For example, Gmail does not have a “send as encrypted” option, so sending any kind of encrypted email to Gmail will not be readable without using a separate decryption program.
There are two de facto standards for encrypting email, and lots of information about them both can be found on the page S/MIME and OpenPGP. However, neither of these solutions offer a generally available email encryption facility. The level of interoperability between different systems is terrible, and no progress appears to be happening today.
One approach might be Hushmail which has been around for a long time and is essentially its own encrypted webmail provider. You would email a Hushmail link to the user, they would click on that and go to the Hushmail site where they could read the email.
