Assume your devices are compromised
I trust it enough no solve my DR scenario. If I was targeted by the NSA, I don't expect this to keep me safe.
I don't think SecretSharingDotNet has had any audits, and I'm pretty sure i hasn't been checked for side-channel attacks. I couldn't find anything in GitHub [1] saying it's no longer maintained though.
I'm pretty sure a well founded attacker would be able to hack me, but I think it's orders of magnitude more likely that I'll forget my master password, I'll get stolen, my apartment will catch on fire or I'll just die. Those are the scenarios I'm preparing for.

At perhaps 2KB per page, you'd need 524288 pages to store a 1GB. That's 1048 reams. Please just use an archival optical disk instead.
