Crypto File Survey

[ChristopherA]

We've begun a survey of current practices for files containing backups or data from crypto-wallets. Currently, we've surveyed Coldcard, Passport, and Gordian Seed Tool on the topics of file names, encryption methods, and contents.

The survey is here:

Any thoughts on what other devices or data we should include? Any thoughts on best practices or other methodologies we should highlight?
