The Boston Diaries

The ongoing saga of a programmer who doesn't live in Boston, nor does he even like Boston, but yet named his weblog/journal “The Boston Diaries.”

Go figure.

The near futility of encryption key management

Contrary to popular belief, encryption per se isn't all that difficult. The algorithms are well known and hardened, and typically, the actual encryption APIs (the bits of the program that do the actual munging of the bits) are pretty easy to use.

It's the encryption key management that's near impossible to handle correctly. Key authorities are a joke. And even if the authorities in charge of encryption keys weren't a joke, it's still hard to exchange keys with random people and know your communications aren't being monitored, never mind obtaining your encryption keys via literal eavesdropping or through power consumption of your laptop (previous two links via tedu).

Obligatory AI Disclaimer

No AI was used in the making of this site, unless otherwise noted.

You have my permission to link freely to any entry here. Go ahead, I won't bite. I promise.

The dates are the permanent links to that day's entries (or entry, if there is only one entry). The titles are the permanent links to that entry only. The format for the links are simple: Start with the base link for this site: https://boston.conman.org/, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

https://boston.conman.org/2000/08/01

You can also specify the entire month by leaving off the day portion. You can even select an arbitrary portion of time.

You may also note subtle shading of the links and that's intentional: the “closer” the link is (relative to the page) the “brighter” it appears. It's an experiment in using color shading to denote the distance a link is from here. If you don't notice it, don't worry; it's not all that important.
