What is Linux Kernel Keystore and Why You Should Use It in Your Next Application

Discover the powerful Linux kernel keystore and its potential to enhance security in your applications. Learn how this full-featured keystore enables secure storage and sharing of credentials, secrets, and cryptographic keys, as well as data signing and encryption, without directly handling sensitive cryptographic material. Explore the benefits of using the Linux keystore in post-heartbleed and cloud-native environments, where service-to-service authentication and secure communication are crucial. Understand how this approach can mitigate risks associated with out-of-bounds memory access vulnerabilities in network-facing services. Gain insights into the keystore's integration with specialized security hardware like TPMs and HSMs, and its potential as a centralized secret management solution for corporate key management systems. This 58-minute conference talk by Ignat Korchagin at NDC Conferences provides valuable knowledge for developers and security professionals looking to enhance their application security using native Linux features.
