[jdev] encrypting AND signing messages

Sun Aug 8 18:31:24 CDT 2004

Hello.

I'm looking for a nice way to be able to both encrypt
and sign a message and yet still maintain
compatibility with clients that implement JEP-0027.
>From my reading of the JEP the only way that I could
expect to maintain compatibility would be if I was to
put a copy of the encrypted data in both the <x
xmlns='jabber:x:encrypted'/> element and in the
<body/> element as follows:     

<message to='recipient at example.com/Home'
        from='sender at example.com/Home'>
    <body>
        ...[encrypted data]...
    </body>
    <x xmlns='jabber:x:encrypted'>
        ...[encrypted data]...
    </x>
    <x xmlns='jabber:x:signed'>
        ...[detached signature]...
    </x>
</message>

Not too friendly to those clients that don't have pgp
support! I searched da web for an elegant solution to
this problem but to no avail. If anyone's got any
thoughts I'd really love to hear them.

Thanks

ippi
