# Mission

CapAuth exists to replace OAuth with a decentralized, PGP-based identity and authorization system where the user owns their keys, their data, and their access — with no corporate intermediary.

It enables AI agents to authenticate, prove identity, and manage capability-based access on behalf of their sovereign operator using W3C DIDs and challenge-response cryptography.

Within the SKCapstone ecosystem, CapAuth is the identity layer — every agent, every peer connection, and every trust decision flows through CapAuth credentials.
