<p>Hi Andrew,</p>
<p>1. Yes.</p>
<p>2. Yes.<br>
</p>
<p>3. I cannot speak for GnuPG, but Werner already answered this.</p>
<p>4. Yes.</p>
<p>5. Yes, however this brought the following discussion, which, as
for me, dramatically overcomplicate things:

<pre class="moz-quote-pre" wrap="">So at this point my understanding is:
1. It is desirable to protect the literal metadata
2. v5 sigs differ from other versions because they include the metadata (for 0x0 and 0x1 sig types only)
3. Gnupg/librepgp would like to implement v6 sigs but will not do so without metadata protection
4. A method exists (subpacket 40) to add metadata protection to v4 sigs
5. A similar method could be used to add metadata protection to v6 sigs
Please correct me if any of the above are inaccurate?
