Secure Multi-Party Computation (MPC) with Go. This project implements secure two-party computation with Garbled circuit protocol.

Refresh/Access JWT authentication server with backend + administration frontend supporting HMAC (HS256 HS384 HS512), RSA (RS256 RS384 RS512), ECDSA (ES256 ES384 ES512) and Ed25519 (EdDSA). See also other repos for Javascript, Python and Go client libraries.
