recoupling detached sig

[Rick van Rein]

Hello,

I've been trying to attach a decoupled signature under a file and make the
whole thing look as a cleartext signature. The signed data was textual.

This does not work, the signature is said to be wrong. Can anyone tell me
if I am doing something vitally wrong? If I understand rfc2440 [OpenPGP]
well, there is nothing special about detached signatures, it's just a
signature packet that's separately put in a file.

WHY you may ask. Okay, I am thinking of providing textual claims online,
which contain a few variables filled in, and end in a cleartext-signature.
The storage of a whole text (possibly even containing contract terms) would
take too much database space, so I'd like to separate out the variables and
the signature, for future recovery. I was wondering if detached signatures
were the way to go for this.


Thanx for any help,

Rick van Rein.
