onMessage and reply with text or AES-256-GCM encrypted files via ctx.reply and ctx.replyFile. - Public bot directory: Publish a Kind-1 gupt-bot listing with publicBot metadata so the bot appears under Talk to bot in the GUPT app. - Use Case: A backup script finishes on a home server; a GuptBot with a dedicated keypair calls bot.reply(process.env.GUPT_USER_PUBKEY, "Backup completed successfully") and only the account owner can decrypt it. ## Quick Start Install gupt-sdk with npm, set GUPT_BOT_KEY and GUPT_USER_PUBKEY environment variables with at least two shared wss relays, then start a GuptBot and call reply to send an encrypted message to the recipient's public key.High-intent search queries and answers about installing and using this skill.
Install gupt-sdk, create a GuptBot with a dedicated bot secret and at least two wss relays, then call bot.reply with the recipient's 64-character public key after bot.start(). The message arrives as an encrypted DM that only that key can decrypt.
Register a handler with bot.onMessage and use ctx.reply for text or ctx.replyFile for files. Inbound messages are serialized per sender with default cooldowns of 1 second and a 20 replies per minute per peer limit.
Yes for message payloads: GUPT sends an encrypted DM to your pubkey instead of plaintext on a public topic. However, it is not an OS wake-up ping while the app is fully closed; that remains the separate ntfy PING path.
ctx.replyFile and bot.replyFile accept a path, Blob, Buffer, Uint8Array, or ArrayBuffer. Bytes are AES-256-GCM encrypted and pinned via Originless with a default cap of 100 MiB, while text messages are capped at 8000 characters.
The bot and recipient must share at least one relay, or the recipient must DM the bot first so it learns a relay hint. Also check that SDK bots ignore other bots' messages unless acceptBotMessages is enabled.
No. Each bot needs its own dedicated secp256k1 keypair passed as GUPT_BOT_KEY. Reusing a personal identity or logging secrets violates the framework's security rules.
