As I move more information online, what information do I need to encrypt? to back-up?
During intervals of the night, when anxiety had kept him waking, the same idea had occurred to him; concealment was his only security[.] 1
Currently, my personal files are backed up to an unencrypted hard drive and, if public, hosted redundantly on github.
- hosting my website on linode and adding a public key certificate
- understanding and implementing PGP for emails
- symmetric encryption for personal documents
Having worked at a refugee resettlement agency, I believe the following documents should be redundantly (and securely) stored online. Maybe also on optical disk?
- national origin documents
- medical records
- financial history

I back up all of my important data remotely. At work, I use a script wrapping duplicity to do incremental encrypted backups to S3 buckets.
I need to save my passwords in a keyring. I’d also like to create a PGP key to share. See riseup.net.
To make strong passwords, I might learn a bit about Shannon Entropy. See pthree.
From Scott Aaronson:
I was reading an obituary of Shannon, asking myself: why did it take till 1948? That the semantics of a message are irrelevant to how to transmit it, that the distribution from which the message was chosen is all that matters, is obvious.
