Google's Tink Cryptographic Library</blockquote>
Abstract:<br>
<br>
<br>
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.<br>
<br>
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.<br>
<br>
Demonstration code will be in Golang and Python, but the Tink
Cryptographic Library also works well with C++, Java, mobile
platforms and more.<br>
<br>
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”.<br>
<br>
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.”<br>
