I can also digitally sign PDF, which Adobe Acrobat will recognize and validate without any hassle to the user. May come in handy. Though it's a paid hardware signing module that is not really that suitable for signing batches of documents in bulk, it remains an option for one-off requests.
I'm not too familiar with PDF signing, but that sounds like it would be more accessible to non-technical people. Would it be too much of a reach to generate a PGP-signed message and have that placed into a signed PDF?
I'd be more than happy with one signed document per roll, listing the coins contained therein. I can envision silkscreening some nice certificates of authenticity with the PGP-signed messages, reminiscent of old 19th century bearer bonds
Given that the final count of 0.5s with series 2 holograms is apparently only 45(!), I'm quite eager to get the "stamp of approval" on them!
I could secondarily PGP-sign the entire (Adobe-signed) PDF file as a binary (creating a separate signature file that GPG recognizes)
Signing PDFs also allows for easy signing of the embedded photos. I have scanned all of the silver coins and most of the recent brass coins.
Also, just keeping this on the radar:
Hi Mike,
No doubt you're busy these days -- can we get an estimate as to when you'll have the time to provide signed docs?
I'd love to have my personal PGP fingerprint included in the message as well, as this would help create a chain of custody for the coins.
Yeah, I still have it on the radar. We're gettin' there.
Any update on this?
I'm closer. Sorry it's taken so long. Am currently doing one-offs upon request as well.
Hi Mike,
As of today, a full
three months has passed since you made the offer to provide signed docs. I'd like to ask again if there's any update on this.
I paid you
55 BTC for two rolls of coins back in
July. That was close to six thousand dollars at the time of purchase, or over
sixteen thousand dollars at today's exchange rate. I'm not asking for a lot here, and given the fact that I've personally enriched you to the tune of several thousand dollars, I'm both upset and amazed that I've had to pester you so many times already to do this.
You've lost me as a paying customer; this can only be described as a complete failure of customer service. Hopefully I'm the exception and others have gotten better treatment so far.
Perhaps you could take some time out of your day to either provide me with the promised documents, or at least give me a definite time frame in which they'll be delivered? I can provide you with my PGP fingerprint via email or PM.
