SJCL is a compact, high-performance JavaScript library for industry-standard AES, SHA-256, and ECC cryptography.

Stanford University researchers developed the Stanford JavaScript Crypto Library (SJCL) to provide a secure, efficient toolkit for browser-based encryption. It implements NIST-approved algorithms (AES-128, 192, 256) and utilizes CCM mode for authenticated encryption to prevent padding oracle attacks. The library is designed for minimal footprint and maximum speed, making it a reliable choice for projects requiring client-side data protection without heavy dependencies.

## Recent Public Talks and Demos

### [Provably Private Inference: Trusted Hardware and In-Browser Verification of LLMs](https://boston.aitinkerers.org/talks/rsvp_hQGG4IgqTVY)

AI inference relies on trusting the operator with your private data: prompts and model responses are visible in the clear to your provider. In this demo, we show how to decouple trust from the model operator, making prompts and model responses provably private. We use remote attestation with AWS Nitro Enclaves and a novel approach to automatic, in-browser cryptographic verification of a running LLAMA model to show that provable private inference is not only possible, but practical and achievable with tooling available today.
