Dang. Mark Klein and John Young (cryptome) in two days. Information is going to have a harder time being free. :(

Damn, I didn't know that John Young passed.

Why the fuck this isn't on the front page will haunt me until I meet him again and ask, on the yonder side.

I didn't know until I read your comment.

Has it even been posted? I would but I can't find a good source.

I've only seen a single-sentence post on the cryptography mailing list by someone I don't know. (I think the news is true, but it's not the clearest source!)

Mark passed a month ago, WSJ just finally got around to writing about it.

OK wow had no idea about the Cryptome guy. I haven't been in the fedi lately.

What source can you find for John Young? Except for one extremely dubious blogspam link I can't find anything confirming this.

My only source so far is this anonymous mailing list post.

Mark wrote a slim volume about this. Well worth a read

Mark was a true American hero.

If you didn't, I was going to.

A hero and a true patriot.
