Making cryptography more accessible and useful with Google's Tink Cryptographic Library
Brian covers the basics of a relatively new library from Google, with demonstration code running on multiple platforms. We'll also delve into some of the more advanced topics related to this code and take a special, deep dive into Key Management Systems.
As part of the discussion, Brian explores the challenges of brittle bytes and how to achieve secure, authenticated access to critical data over time. Demos cover code running on tiny little machines and bigger&emdash;but still bargain&emdash;builds.
Demonstration code will be in Golang and Python, but the Tink Cryptographic Library also works well with C++, Java, mobile platforms and more.
We'll also walk through and demonstrate code and the use of cryptography in “nostr”, which stands for “Notes and Other Stuff Transmitted by Relays”.
According to its chief architect, nostr is “The simplest open protocol that is able to create a censorship-resistant global ”social“ network once and for all. It doesn't rely on any trusted central server, hence it is resilient; it is based on cryptographic keys and signatures, so it is tamperproof; it does not rely on P2P techniques, therefore it works.”
