  • Can I delete Nostr accounts? I deleted from the OpenVibes app. I didn’t know I can do that.

    harry reafor LYQ6GgAqg70 unsplash scaled

    Nostr accounts cannot be fully deleted because they are based on a decentralized protocol. Instead of traditional “accounts,” Nostr uses key pairs (public and private keys) to represent users. Here’s what you can do:

    • Clear Metadata: You can delete or clear all metadata (e.g., username, profile picture) associated with your public key. This effectively “empties” your profile.
    • Abandon the Key: Simply stop using the key and generate a new one. The old profile will persist on relays but remain inactive.
    • Delete Content: Some apps, like Damus, allow you to mark content as deleted, but this is not enforced across all relays and doesn’t guarantee full removal.
    • OpenVibe App: If you used OpenVibe to manage your Nostr activity, removing your account there only affects the app, not the underlying Nostr data.

    Due to the decentralized nature of Nostr, true deletion is not possible, as data may still exist on relays or in backups.

  • How to get a verification badge using your own server on Damus

    riswan ratta oQinz7ct9ww unsplash scaled

    1. Convert Public Key to HEX format

    1. Copy the Public Key from the Damus home screen
    2. Open Damus’ KeyConverter and convert Public Key to HEX format

    2. Creating a JSON file

    1. Use a code editor (e.g. XCode on Mac)
    2. Create a new folder on your desktop
    3. Create “nostr.json” file
    4. Enter the code below and replace <name> with your own Damus ID name (the string after @), and <pubkey> with the hex key created above.
    {"names": {"<name>": "<pubkey>"}}

    3. Upload JSON file

    1. Open the server’s file manager
    2. Create a “.well-known” folder in the public_html folder
    3. Upload the nostr.json file in the “.well-known” folder

    4. Enter CORS settings in .htaccess file

    Add the following code between the IfModule parentheses in the .htaccess file depending on the server software.

    • For Apache: Header set Access-Control-Allow-Origin "*"
    • For Nginx: add_header 'Access-Control-Allow-Origin' '*';
    <IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
Header set Access-Control-Allow-Origin "*"
</IfModule>

    The server I’m using is an XServer, so I used Apache’s.

    5. Set NIP-05 VERIFICATION

    1. Tap “Edit” on the Damus home screen
    2. Enter “DamusIDname@yourservername” in NIP-05 VERIFICATION
    3. Tap “Save”

    If configured correctly, the authentication batch will be your server name. Tap the verification badge to access your site.

  • Choosing the Best Security for Nostr: HEX, nsec, ncryptsec, and Bunker Explained

    ted balmer VYutFw1k94k unsplash scaled

    Nostr is a fast-growing decentralized social protocol, and securing your account is critical. With various login methods—HEX/nsec, ncryptsec encryption, bunker remote signers, and browser extensions like nos2x—users may be unsure which approach offers the best balance of safety and convenience. This article breaks down the differences and best practices for each option.

    Understanding Nostr Key Formats: HEX vs. nsec

    Your Nostr identity is tied to a cryptographic private key. This key can be expressed as:

    • HEX: A 64-character hexadecimal string (raw private key).
    • nsec: A Bech32-encoded, user-friendly string version of your key.

    Security Implication:
    Both formats represent the same secret information. The risk lies not in the format, but in the exposure—never enter your HEX or nsec into untrusted apps or websites, as stealing the key means losing your account forever!

    ncryptsec (NIP-49): Encrypted Key Storage

    As the ecosystem matures, the ncryptsec format (defined in NIP-49) is gaining support. Here’s what you need to know:

    • What is ncryptsec?
      It’s your private key, encrypted with a password and presented as a secure string.
    • Why use it?
      Even if someone finds your ncryptsec, they can’t access your Nostr identity without your password.
    • How to set it up?
      Most modern Nostr apps and browser tools let you encrypt your existing key or generate a new one, prompting you to set a password. Always backup your ncryptsec and password safely.

    Bunker: Remote Signing for Ultimate Safety

    Bunker refers to remote signing services such as nsecBunker or nsec.app.

    • What does a bunker do?
      Your key never leaves the “bunker” server, which signs actions for you after you approve them. Apps only receive the signature, not your key.
    • Advantages:
      • Private key is never exposed to any third-party app or device.
      • Great for users with multiple devices or organizations/teams.
      • Bunker permissions can be revoked if a device is lost or compromised.
    • How to get one:
      Use a hosted service like nsec.app, or self-host your own bunker using nsecBunker.

    Browser Extensions like nos2x

    • nos2x acts as a local signer: you approve actions, and the extension signs them—never exposing your real key to web apps.
    • Recent features now include ncryptsec support, letting you encrypt and back up your key with a password inside the browser.
    • How to use it:
      • Install nos2x, import or generate your key, optionally encrypt it as ncryptsec for backup.
      • All signing happens locally; your key is never sent to websites.

    Which is Best?

    ScenarioBest Method
    Simplicity & Passwordncryptsec (encrypted key)
    Shared/Advanced UseBunker remote signer
    Browser Conveniencenos2x extension with ncryptsec
    Legacy compatibilitynsec/HEX (not recommended!)

    Summary:

    • Never use unencrypted nsec/HEX keys in untrusted environments.
    • Use ncryptsec for simple backup and import across apps.
    • Use a bunker for the highest level of protection, permission management, and multi-device safety.
    • Use nos2x or similar extensions for browser-based local signing—especially with ncryptsec support for backup.

    Securing your Nostr identity isn’t just about convenience—it’s your digital sovereignty. Choose the setup that best fits your technical comfort, and always follow secure backup and recovery practices!

    Stay safe, and enjoy your journey on Nostr!
