Hello,
I am studying the RFC 4880 and I am using GPG as a tool to experiment.
I explored PGP signatures. You can find notes here :
https://github.com/denis-beurive/bouncy-castle-examples/blob/master/doc/pgp-sig.md
I pretty much explore all types of signatures, except one : *Standalone
signature (sigclass = 0x02*).
In the RFC, you can read :
This signature is a signature of only its own subpacket contents. It is
calculated identically to a signature over a zero-length binary document.
Note that it doesn't make sense to have a V3 standalone signature.
This description remains mysterious. I looked for this signature in various
PGP documents but could not spot one.
*Is it possible to generate this kind of signature with GPG ?*
*What is this signature used for ?*
My intuition tells me that it may be used in association with hashed
subpackets. However, I cannot find any document to confirm this intuition.
Thanks for your help,
Denis
