I was just wondering what happens to a valid signature on a gpg key<br>
when the key is revoked or goes out of date ?<br>
<br>
I have two keys that are a few years old. I looked over the signatures<br>
of the keys that signed mine , several have been revoked. So, does<br>
this lessen the strength of my key, are the signatures are still valid?<br>
