Need to send encrypted e-mail to cell phone (text message) using ASP and Exchange

I am working on an ASP form/script which will send internal e-mails within our company and also to company-issued cell phones.  My form output is a single sentence summary of form data.  My IT security team tells me that I need to send the e-mails out in an encrypted form.

QUESTIONS:

1.  How do I encrypt an e-mail in ASP?
2.  If I encrypt it, how will the cell phone be able to read the message?  DOes it have enough smarts to decode an encrytped e-mail?

Sorry if I am asking stupid questions.  I am learning as I go, and not getting much support from the IT folks here.

Please see my mail generation code below...


.......code to build message.....

set cdoConfig = CreateObject("CDO.Configuration")
        with cdoConfig.Fields
            .Item("http://schemas.microsoft.com/cdo/configuration/sendusing")=2
            .Item("http://schemas.microsoft.com/cdo/configuration/smtpserver")="IP.ADDR.OF.SERVER"
            .Item ("http://schemas.microsoft.com/cdo/configuration/smtpserverport")=25
            .Update
        end with
       
        set myMail=CreateObject("CDO.Message")
        with myMail
            set .Configuration = cdoConfig
            .From="address@company.com"
            .Subject=subj
            .To="recipent_phone_#@txt.att.net"
            .TextBody=message
            .Send  
        end with

......close variables, end script, redirect.........

Cell phones are not smart enough to decrypt emails at this time (some can but what an Administrative nightmare).

You're best bet is to instead save the message(s) you want to a database.  Then write some code that will show the message you want on a webpage that is secure and encrypted itself if it is that important (HTTPS) which phones can handle.

Then you would send an email with a link in it to all the phones and desktop users that has a link like (https://www.mysite.com/supersecretmessage.aspx?Code=39002rjfj2f029f and then they can easily authenticate via the website instead.

Best of luck to you!

I need to send a message.  The phones I am sending to are 'dumb phones'.  They can receive text messages, but are not web enabled...

Am I trying to do something that cannot be done?

Mostly yes, you are trying to do something that cannot be done.  You would need to develop software for each mobile device that can decrypt your message properly.

It would be best to send the link to a secure site with the message to avoid that type of problem.
