@intx/crypto

Web Crypto-backed cryptographic provider. Ed25519 key generation, import, sign, and verify; canonicalisation of text and byte payloads; SSH and PGP detached signature formats; ASCII armoring.

@intx/crypto/keys exposes Ed25519 key generation, import, public-key derivation, signing, and verification without loading the SSH or PGP modules.

The exported Ed25519Crypto implements the CryptoProvider contract that the mail and storage layers depend on. Consumed by @intx/mime (detached PGP signatures on outbound mail), @intx/storage-isogit (commit signing), @intx/mail-memory (per-address keys for the in-process transport), and @intx/hub-sessions (per-agent key material).

import { generateKeyPair, createEd25519Crypto } from "@intx/crypto";

const keyPair = await generateKeyPair();
const provider = createEd25519Crypto(keyPair);

const signature = await provider.sign(new TextEncoder().encode("hello"));
