<pre class="moz-quote-pre" wrap="">I recall from the early days of PGP that there was a way to create a corporate key, fragmented into a certain number of potions, which would require some quorum to be able to perform decryption. I pored over the GnuPG documentation but could not find an equivalent. Perhaps I’m just getting the terminology wrong. Is this still possible in OpenPGP and therefore in GnuPG?

The number of shares created, and the number needed to retrieve
the secret<br>
are set at splitting time. The number of shares required to
re-create the<br>
secret can be chosen to be less that the number of shares created,
so any<br>
large enough subset of the shares can retrieve the secret.<br>

This scheme allows a secret to be shared, either to reduce the
chances that<br>
the secret is lost, or to increase the number of parties that must
