is there any way to separate a message that was signed and encrypted to a
dh key, into a free-standing verifiable signed message?

am aware that rfc 2440 requires this, but has it actually been 'tested'
with dh keys to see if it is so?

{do 'not' mean to criticize dh keys,
on the contrary, would find it a security 'benefit' of a dh key if it could
'not' be done, even if it required reconsideration of this aspect of the
rfc-2440 }

so far, have been able to separate messages signed and encrypted to an rsa
key, both for rsa and dh/dss signatures


tia,

vedaal
