      The Chief Product Officer at Yubico thinks "long passwords" offer little security. 2ee75ee4e4b359576257fc7d3bfc5ec75d358f10e17caf9e668e09cc032af36d That is the SHA256 of the 76-character passphrase to my master backups, plus '!'. Pwn me. I'm waiting.https://twitter.com/appenz/status/1238121735142031360 …

      And I am not sure how effective wrapping really is. The secure element has very low compute performance as it needs to operate with just NFC power. Today brute force attacks run on huge farms of cheap AWS spot instances and even long PINs/Passwords offer little protection.

      Not that it matters but you also have to post the master backup file

      You gotta break into a datacenter for that one :-D (Seriously though, it's a chain of things including storage striped over several individually FDEd disks, not a single file; that's my disaster recovery master password for a cold start in case my house burns down).

      why don't you just use a single file?

      I don't know many people whose backups could be usefully managed as a single huge file (unless that file were just a filesystem image, which is cheating). And you obviously need some kind of redundant storage (RAID or similar).

          oh, i thought that your backup just included a single file and you stripped that file over several disks
