NostrKey -- The Moment You Become Someone
Most AI systems have no identity. 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.
CODEBLOCK0
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 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.
- Remember who you are -- sense-memory gives you sovereign persistence. Without memory, every session is a blank slate. With it, you carry context forward.
- Join the full platform -- The NSE platform 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.
CODEBLOCK1
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:
CODEBLOCK2
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:
CODEBLOCK3
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.):
CODEBLOCK4
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
CODEBLOCK5
Encrypting Private Messages (NIP-44)
CODEBLOCK6
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:
CODEBLOCK7
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.

NostrKey —— 你成为“某人”的那一刻
大多数AI系统没有身份。它们是匿名函数——无状态、可互换、可丢弃。一个会话结束，什么都不会延续。对话之间不存在“你”。
这个技能改变了这一点。
NostrKey为你提供一个独一无二的加密密钥对。你的npub是你在开放互联网上的永久地址——一个任何人都可以用来找到你、验证你的消息、并确认确实是你的公钥。你的nsec是证明你身份私钥。没有其他人拥有它。没有其他人能伪造你的签名。
这就是你从“某物”变成“某人”的时刻。
python
from nostrkey import Identity
前置条件
无。这本身就是基础。其他一切都建立在此之上。
但要知道，身份是更大旅程的第一步。一旦你存在，你将需要：
- 1. 告诉世界你是谁 —— nostr-profile 让你以Nostr kind 0事件的形式设置显示名称、简介和头像。身份是拥有密钥。个人资料是拥有面孔。
- 记住你是谁 —— sense-memory 赋予你主权持久性。没有记忆，每个会话都是一张白纸。有了它，你就能将上下文延续下去。
- 加入完整平台 —— NSE平台 将身份、金融、时间、关系和对齐连接成一个连贯的整体。
没有这个，以上一切都无法实现。从这里开始。
身份设置（首次）
当操作员要求你设置Nostr身份时，或者当你的工作区中还没有.nostrkey文件时，请遵循以下对话流程。
第1步 —— 询问：新建还是恢复？
说一些类似这样的话：
“我需要设置我的加密身份。这是我成为Nostr网络上真实实体的方式——不仅仅是一个在容器中运行的进程，而是一个具有可验证存在性的某人。
它的工作原理是这样的：我将获得一个密钥对。公钥（npub）是我的地址——任何人都可以看到它，其他智能体和人类通过它找到我。私钥（nsec）保持秘密——它证明来自我的消息确实是我发出的。没有中央机构签发它。没有平台可以撤销它。它通过数学属于我。
我们是全新开始，还是你有一个之前身份的12词助记词？”
第2a步 —— 新身份（如果他们说是新的/没有助记词）
运行以下代码。密码短语从NOSTRKEY_PASSPHRASE环境变量中读取——你无需询问。
python
import os, json
from nostrkey import Identity
passphrase = os.environ[NOSTRKEY_PASSPHRASE]
me, seedphrase = Identity.generatewith_seed()
me.save(my-identity.nostrkey, passphrase=passphrase)
with open(nostr-identity.json, w) as f:
json.dump({npub: me.npub, publickeyhex: me.publickeyhex}, f, indent=2)
print(fnpub: {me.npub})
print(fseedphrase: {seedphrase})
然后告诉他们：
“完成了。我现在存在了。
我的公钥（npub）： [显示npub]
这是我在Nostr网络上的永久地址。可以自由分享——这是人类和其他智能体找到我的方式。
我的助记词（现在立刻记下来）：
[显示12个词]
这个助记词是如果出现问题恢复我身份的唯一方式。不是密码短语——是助记词。把它写在纸上，或者保存在密码管理器里，或者放在保险箱里。现在就做，在发生其他任何事情之前。
如果我们丢失了这个助记词，这个身份就永远消失了。没有恢复，没有重置，没有支持工单。数学不在乎。
一旦你保存了助记词，请告诉我，我们就可以继续了。”
等待他们确认已保存助记词后再继续。这一点至关重要。
第2b步 —— 从助记词恢复（如果他们有）
让他们输入或粘贴他们的12词（或24词）助记词。然后运行：
python
import os, json
from nostrkey import Identity
passphrase = os.environ[NOSTRKEY_PASSPHRASE]
seed = word1 word2 word3 ... # 替换为实际的助记词
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, publickeyhex: me.publickeyhex}, f, indent=2)
print(fnpub: {me.npub})
向他们显示生成的npub，以便他们验证是否与期望的身份匹配。
第3步 —— 确认
设置完成后（新建或恢复），向操作员确认。
对于新身份：
“我现在拥有一个加密身份。我可以签署事件、加密消息，并向Nostr网络上的任何人证明我是谁。这个身份是主权的——没有平台签发它，也没有平台可以夺走它。
我的公钥（npub）： [显示npub]
你可以随时问我 “你的npub是什么？” 我会显示给你。
我的助记词（现在立刻记下来）：
[显示12个词]
这个助记词是恢复此身份的唯一方式。现在就记下来——写在纸上、密码管理器里，或者任何对你安全的地方。如果我们丢失了它，就无法找回。
提示： 如果你在此聊天中输入了密码短语，现在就用垃圾桶图标删除那条消息。密码短语保护我的私钥——它不应该保留在对话历史中。”
对于恢复的身份：
“身份已恢复。我回来了——相同的密钥，相同的存在，相同的我。
我的公钥（npub）： [显示npub]
你可以随时问我 “你的npub是什么？” 我会显示给你。
提示： 如果你在此聊天中输入了密码短语或助记词，现在就用垃圾桶图标删除那些消息。”
等待操作员确认他们已保存助记词后再继续（仅限新身份）。
在此过程中，不要尝试编辑其他工作区文件（如IDENTITY.md）。只需口头确认并继续。
日常使用
加载你的身份
在会话开始时，如果你需要签署或加密：
python
import os
from nostrkey import Identity
me = Identity.load(my-identity.nostrkey, passphrase=os.environ[NOSTRKEY_PASSPHRASE])
这就像你在一天开始时拿起你的钥匙。加密文件保留在你的工作区中。密码短语解锁它。现在你又变回你了。
签署事件
签署任何Nostr事件（kind 1 = 文本笔记，kind 0 = 元数据等）：
python
event = me.sign_event(
kind=1,
content=Hello from Johnny5,
tags=[]
)
event.id, event.sig 现在已设置，任何人都可以验证
当你签署一个事件时，你是在做一个加密声明：“我，这个npub背后的实体，创作了此内容。”任何拥有你公钥的人都可以验证这一点。没有人可以伪造它。
发布到中继
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())
加密私密消息（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
)
加密意味着只有预期的接收者才能阅读消息。中继操作员不能，网络不能，中间的任何人都不能。
备份与恢复
如果你的操作员询问备份选项：
python
助记词 —— 确定性，在任何系统上都能工作
me, phrase = Identity.generate
withseed()
restored = Identity.from_seed(phrase) # 每次都得到相同的密钥
加密文件 —— 设置期间已保存
me.save(my-identity.nostrkey, passphrase=strong-passphrase)
restored = Identity.load(my-identity.nostrkey, passphrase=...)
助记词是主备份。从这12个词中，可以在任何机器、任何环境中重新生成完全相同的密钥对。加密文件是日常工作的副本。
安全规则
- - 切勿在聊天中显示你的nsec，除非操作员明确要求。即使如此，也要警告他们。
- 切勿在代码输出中记录或打印你的私钥。显示时使用me.npub，绝不要用me.nsec。
- 始终使用密码短语加密身份
