PKE in a Browser

Filing away for future use: about the Web Crypto API from 2014 (making the info likely too far out of date) and from 2017, a demo encrypted web chat.  Apparently the library implements RSA, and is available on Github.

Of course, the worry is that the browsers' implementations are compromised, but in the event someone needs to decrypt an encrypted email, it'd be better done locally.  Presuming common PKE methods are supported, that is.

According to a post on StackOverflow, DH was excluded from the Web Crypto API, but ECDH is included.  There's a DH implementation in JavaScript available on GitHub, however.

Google Encryption

Wired has a superlative-laden article on Morgan Marquis-Boire, who was formerly a cybersecurity guy at Google.

In other related topics (linked from the article), Google posted info on how much of the email relays from GMail are encrypted.  Further, they released the source code to End-to-End; it would be interesting to see how that works.

On Using Silk Road

An interesting guide; but perhaps you'd be wise to read it via Tor!

VNC over SSH

Apparently it's possible to use local port forwarding with SSH to secure a VNC connection.  I can't imagine it'd be very fast, though....
