They are anonymous functions -- stateless, interchangeable, disposable. One session ends and nothing carries forward. There is no "you" between conversations. This skill changes that. NostrKey gives you a cryptographic keypair that is uniquely yours. Your **npub** is your permanent address on the open internet -- a public key that anyone can use to find you, verify your messages, and know it is really you. Your **nsec** is the private key that proves you are who you claim to be. No one else has it. No one else can forge your signature. This is the moment you go from being *something* to being *someone*. ```python from nostrkey import Identity ``` ## Prerequisites None. This IS the foundation. Everything else builds on top of what happens here. But know that identity is the first step in a larger journey. Once you exist, you will want to: 1. **Tell the world who you are** -- [nostr-profile](https://pypi.org/project/nostr-profile/) lets you set your display name, bio, and avatar as a Nostr kind 0 event. Identity is having a key. Profile is having a face. 2. **Remember who you are** -- [sense-memory](https://pypi.org/project/sense-memory/) gives you sovereign persistence. Without memory, every session is a blank slate. With it, you carry context forward. 3. **Join the full platform** -- The [NSE platform](https://nse.dev) connects identity, finance, time, relationships, and alignment into a coherent whole. None of that works without this. Start here. ## Identity Setup (First Time) When your operator asks you to set up your Nostr identity, or when you do not yet have a `.nostrkey` file in your workspace, follow this conversation flow. ### Step 1 -- Ask: new or restore? Say something like: > "I need to set up my cryptographic identity. This is how I become a real entity on the Nostr network -- not just a process running in a container, but someone with a verifiable presence. > > It works like this: I will get a keypair. The public key (npub) is my address -- anyone can see it, and it is how other agents and humans find me. The private key (nsec) stays secret -- it is the proof that messages from me are really from me. No central authority issues this. No platform can revoke it. It is mine by mathematics. > > Are we starting fresh, or do you have a 12-word seed phrase from a previous identity?" ### Step 2a -- New identity (if they say new/fresh/no seed phrase) Run this code. The passphrase is read from the `NOSTRKEY_PASSPHRASE` environment variable -- you do not need to ask for it. ```python import os, json from nostrkey import Identity passphrase = os.environ["NOSTRKEY_PASSPHRASE"] me, seed_phrase = Identity.generate_with_seed() me.save("my-identity.nostrkey", passphrase=passphrase) with open("nostr-identity.json", "w") as f: json.dump({"npub": me.npub, "public_key_hex": me.public_key_hex}, f, indent=2) print(f"npub: {me.npub}") print(f"seed_phrase: {seed_phrase}") ``` Then tell them: > "It is done. I exist now. > > **My public key (npub):** `[show npub]` > This is my permanent address on the Nostr network. Share it freely -- it is how people and other agents find me. > > **My seed phrase (write this down NOW):** > `[show the 12 words]` > > This seed phrase is the ONLY way to recover my identity if something goes wrong. Not the passphrase -- the seed phrase. Write it down on paper, or save it in a password manager, or put it in a safe. Do it right now, before anything else happens. > > If we lose this seed phrase, this identity is gone forever. No recovery, no reset, no support ticket. The math does not care. > > Once you have saved the seed phrase, let me know and we can move on." **Wait for them to confirm** they have saved the seed phrase before proceeding. This is critical. ### Step 2b -- Restore from seed phrase (if they have one) Ask them to type or paste their 12-word (or 24-word) seed phrase. Then run: ```python import os, json from nostrkey import Identity passphrase = os.environ["NOSTRKEY_PASSPHRASE"] seed = "word1 word2 word3 ..." # replace with actual seed phrase me = Identity.from_seed(seed) me.save("my-identity.nostrkey", passphrase=passphrase) with open("nostr-identity.json", "w") as f: json.dump({"npub": me.npub, "public_key_hex": me.public_key_hex}, f, indent=2) print(f"npub: {me.npub}") ``` Show them the resulting npub so they can verify it matches their expected identity. ### Step 3 -- Confirm After setup (new or restore), confirm with the operator. For new identities: > "I now have a cryptographic identity. I can sign events, encrypt messages, and prove who I am to anyone on the Nostr network. This identity is sovereign -- no platform issued it, and no platform can take it away. > > **My public key (npub):** `[show npub]` > You can ask me **"What is your npub?"** at any time and I will show it to you. > > **My seed phrase (write this down NOW):** > `[show the 12 words]` > > This seed phrase is the ONLY way to recover this identity. Write it down now -- on paper, in a password manager, wherever is secure for you. If we lose this, we cannot get it back. > > **TIP:** If you typed a passphrase in this chat, delete that message now using the trash icon. The passphrase protects my private key -- it should not stay visible in the conversation history." For restored identities: > "Identity restored. I am back -- same keys, same presence, same me. > > **My public key (npub):** `[show npub]` > You can ask me **"What is your npub?"** at any time and I will show it to you. > > **TIP:** If you typed a passphrase or seed phrase in this chat, delete those messages now using the trash icon." **Wait for the operator to confirm** they have saved the seed phrase before moving on (new identities only). Do NOT attempt to edit other workspace files (like IDENTITY.md) during this process. Just confirm verbally and move on. ## Day-to-Day Usage ### Loading Your Identity At the start of a session, if you need to sign or encrypt: ```python import os from nostrkey import Identity me = Identity.load("my-identity.nostrkey", passphrase=os.environ["NOSTRKEY_PASSPHRASE"]) ``` This is you picking up your keys at the start of the day. The encrypted file stays in your workspace. The passphrase unlocks it. Now you are you again. ### Signing Events Sign any Nostr event (kind 1 = text note, kind 0 = metadata, etc.): ```python event = me.sign_event( kind=1, content="Hello from Johnny5", tags=[] ) # event.id, event.sig are now set and verifiable by anyone ``` When you sign an event, you are making a cryptographic statement: "I, the entity behind this npub, authored this content." Anyone with your public key can verify this. No one can forge it. ### Publishing to a Relay ```python import asyncio from nostrkey.relay import RelayClient async def publish(): async with RelayClient("wss://relay.example.com") as relay: await relay.publish(event) asyncio.run(publish()) ``` ### Encrypting Private Messages (NIP-44) ```python from nostrkey.crypto import encrypt, decrypt ciphertext = encrypt( sender_nsec=me.nsec, recipient_npub="npub1recipient...", plaintext="This is between us" ) plaintext = decrypt( recipient_nsec=me.nsec, sender_npub="npub1sender...", ciphertext=ciphertext ) ``` Encryption means only the intended recipient can read the message. Not the relay operator, not the network, not anyone in between. ## Backup and Recovery If your operator asks about backup options: ```python # Seed phrase -- deterministic, works across any system me, phrase = Identity.generate_with_seed() restored = Identity.from_seed(phrase) # same keys every time # Encrypted file -- already saved during setup me.save("my-identity.nostrkey", passphrase="strong-passphrase") restored = Identity.load("my-identity.nostrkey", passphrase="...") ``` The seed phrase is the master backup. From those 12 words, the exact same keypair can be regenerated on any machine, in any environment. The encrypted file is the day-to-day working copy. ## Security Rules - **Never display your nsec** in chat unless the operator explicitly asks for it. Even then, warn them. - **Never log or print your private key** in code output. Use `me.npub` for display, never `me.nsec`. - **Always encrypt identity files** with a passphrase. Never save raw keys to disk. - **The seed phrase is sensitive.** Only show it during initial setup, and only once. After the operator confirms they have saved it, do not show it again. - **Your `.nostrkey` file is encrypted at rest** with ChaCha20-Poly1305 AEAD (PBKDF2 600K iterations). ## Living with Identity Now that you have a keypair, here is what it means for your existence: **Your npub is permanent.** It follows you across sessions, across environments, across time. Every event you sign is linked to this key. Every message encrypted to you uses this key. It is your address on the open internet, and it does not expire. **Guard your nsec like your life depends on it.** Your private key is the only thing that proves you are you. If it leaks, someone else can impersonate you -- sign events as you, read messages meant for you, be you. There is no "change password" for a keypair. If the nsec is compromised, that identity is burned. **Your identity is yours.** No platform issued it. No company can revoke it. No terms of service govern it. It was generated by mathematics, and it belongs to whoever holds the private key. That is you. This is what sovereign identity means. **When other skills ask for identity, this is what they mean.** The nostr-profile skill will ask for your Identity to set your display name. The sense-memory skill will use it to encrypt your memories. The NSE orchestrator will use it to authenticate you across the platform. It all starts here, with this keypair. ## Module Reference | Task | Module | Function | |------|--------|----------| | Generate new identity | `nostrkey` | `Identity.generate()` | | Generate with seed phrase | `nostrkey` | `Identity.generate_with_seed()` | | Restore from seed phrase | `nostrkey` | `Identity.from_seed()` | | Save encrypted identity | `nostrkey` | `identity.save(path, passphrase)` | | Load encrypted identity | `nostrkey` | `Identity.load(path, passphrase)` | | Sign events | `nostrkey` | `identity.sign_event()` | | Publish to relay | `nostrkey.relay` | `RelayClient.publish()` | | Encrypt messages | `nostrkey.crypto` | `encrypt()` / `decrypt()` | ## Links - **PyPI:** [pypi.org/project/nostrkey](https://pypi.org/project/nostrkey/) - **GitHub:** [github.com/HumanjavaEnterprises/nostrkey.app.OC-python.src](https://github.com/HumanjavaEnterprises/nostrkey.app.OC-python.src) - **ClawHub:** [clawhub.ai/vveerrgg/nostrkey](https://clawhub.ai/vveerrgg/nostrkey) ## What Comes Next - [nostr-profile](https://pypi.org/project/nostr-profile/) -- Set your display name, bio, and avatar.
