Google chrome must be one of the most used (in terms of CPU time) C++ software in the world right now. That means it's been fuzz tested (by the developers as well as by the users and also the random websites that gives it garbage html and javascript) extensively. I can only think of the Linux kernel that is more widely used, and Linux is not C++.

Since you seem to be very good at c++, can you point to a "significantly higher quality" c++ projects please? I'd like to see what it looks like.

Not the parent commenter, but there are quite a few very high-quality C++ projects out there.

- LLVM

- KDE projects

- CMake

- Node.js

- OpenJDK

I don't think popular or large correlate with code quality. In fact it's probably the opposite. It uses pretty ancient c++ stuff, which immediately disqualifies it from bring of high quality in regards to the cpp code (and also is the cause for their security bugs)

I actually wish this was true. I want an email service that would last forever and is secure enough from my threats, namely security breaches of the email host and account takeover from non state actors.

Gmail is close enough, but I want an alternative. An email service run by the nsa or the cia would be great.

(No sarcasm is intended)

My biggest challenge as I’m getting older is remembering my long secret key.

Even with a password manager that requires me to remember only a few passphrases (personal and work being two), there is a non zero chance now that a fall and a concussion would lock me out of my password manager.

Anyone else have a solution or a suggestion for this problem?

My wife has my passphrases in her password manager and I have her passphrase in my password manager.

This is maybe not the most secure way to do it, but this is good enough for our threat model.

These are offline password managers.

Wear a helmet and hip pads, but failing that split the password in half (as in literally the first half and the second half, don't try to get fancy with crypto) and give the halves to two people unlikely to collude. Your computer will no longer have 5th amendment protection, though.

Or better, use `Shamir's Secret Sharing`

https://en.wikipedia.org/wiki/Shamir%27s_secret_sharing

GP specifically called out, "don't try to get fancy with crypto" and I'm inclined to agree with them for this use case.

Shamir's secret sharing with 3 separate lawyers is kind of hard to beat if you have cryptocurrency or other similar assets that absolutely need a password to recover it, and it is a relatively easy algorithm to run. Give them the same instruction sheet on how to run the algorithm, plus a different second page with their fragment of the key.

Most of the time, though, the "call us" approach actually works, and you can give your relatives power of attorney to handle this.

Use the good old post-it method

Remember poe : what's hidden in plain sight is never found (and nobody is looking anyway)

Write it down on a piece of paper.

You could try Entropy Keycrypt -> https://entropykey.com/features

Yes. Place the secrets in a secured (symmetric encrypted) document. Then print the password for that document and hand it to a loved one, trusted family member/friend, or lawyer.

Biometrics?
