Hybrid Public Key Encryption, simplified
Data-at-Rest Encryption in DuckDB
DuckDB v1.4 ships database encryption capabilities. In this blog post, we dive into the implementation details of the encryption, show how to use it and demonstrate its performance implications.
FOKS - Federated Open Key Service
FOKS provides a secure, end-to-end encrypted Git hosting service. Your data is encrypted on your machine before it hits the server, and the server never sees data or filenames in unencrypted form. FOKS uses PQ-secure public-key cryptography, securing all end-to-end encrypted data against future quantum attacks. Your secrets are safe, even in the event of server compromise.
HEIR: Homomorphic Encryption Intermediate Representation
HEIR is a compiler toolchain for fully homomorphic encryption (FHE). We aim to be the industry-standard compiler for FHE. Application developers, compiler engineers, hardware designers, and cryptography researchers can build upon HEIR to accelerate the research and development of production-strength privacy-first software systems.
