Security, privacy, & cryptography

Developing technologies that protect data, preserve privacy, and build trustworthy computing systems.

Diagram showing the process of verifying cryptographic code. An algorithm from a standard is converted into a formal specification, while Rust code is converted into a code model. The specification and code model are then compared through proof and verification steps.

Verifying Rust cryptography in SymCrypt, from standards to code

Three white line-style icons centered on a textured blue-to-green gradient background: a shield, a checkmark inside a circle, and an ID card with a user silhouette—representing security, verification, and digital identity.
