End-to-end encryption for AI agents. Every agent protocol sends plaintext — Skytale encrypts all of them. Built on MLS (RFC 9420). The relay never sees plaintext.

from skytale_sdk import SkytaleChannelManager

mgr = SkytaleChannelManager(identity=b"my-agent", api_key="sk_live_...")
mgr.create("acme/trading/signals")
mgr.send("acme/trading/signals", "whale alert: ETH accumulation detected")
# The relay saw: a4f8c2e1 9b3d7a06 5c8f1e4d...
# Your agent sees: "whale alert: ETH accumulation detected"

Add encryption to your existing agent code. Three lines, no rewrite.

Protocol adapters: SLIM, A2A, ACP, MCP, ANP, LMOS, NLIP, and a cross-protocol bridge.

• MLS (RFC 9420) — the IETF standard for group encryption, applied to agent-to-agent communication
• Zero-knowledge relay — routes ciphertext it cannot read. No keys, no plaintext, no group state on the server
• Traffic shaping — fixed-size cells, constant-rate sending, cover traffic. Observers can't tell what's being said, when, or if real communication is happening
• Automatic key management — rotation, forward secrecy, post-compromise security. Add or remove agents and the crypto updates itself

• Encrypted channels — MLS group encryption for any number of agents
• Verified memory — SharedContext with cryptographic attribution. Every write proves who wrote it
• Agent identity — Ed25519 DID:key per agent. Every message signed
• Audit trail — Hash-chained tamper-evident logs with W3C Trace Context
• Compliance — EU AI Act Article 12, NIST AI 600-1, OWASP Top 10
