☽PRIVATEER_RECORD

In the age of sail, a captain about to depart on a covert mission received sealed orders, documents prepared by the Admiralty, locked under wax, to be opened only when the ship was at sea and beyond enemy reach. No port official could read them. No informant could intercept them. Only the captain, in the right place at the right time, could break the seal. SEALED_ORDERS gives you the same mechanism for any message.

╔══ DESCRIPTION ═════════════════╗

Secure communications do not require a secure channel. They require good cryptography. SEALED_ORDERS generates X25519 key pairs locally, offline, and uses them to encrypt messages that can be posted on Discord, Reddit, SMS, or any public surface in the world. To anyone without the matching private key, it is noise. To the recipient, it is the message.

╔══ CAPABILITIES ════════════════╗

▸X25519 key pair generation: local, offline, instantly generated; no registration, no server, no account

▸Public key encryption: type a message, paste your contact's public key, receive a raw ASCII ciphertext block ready to post anywhere

▸One-click ciphertext: output is a self-contained ASCII block; paste it into any chat, forum, SMS, or social platform

▸Offline key management: import, export, and label contact public keys; stored locally, never transmitted

▸Clearnet-safe output: ciphertext is indistinguishable from random data; reveals nothing about the sender, recipient, or content

▸Message signing: optionally sign ciphertext with your own private key so the recipient can verify it came from you

▸Decryption UI: paste any ciphertext block and decrypt it with your private key in one step

▸Key fingerprint display: verify contact key authenticity via truncated fingerprint comparison

╔══ SECURITY_PROTOCOLS ══════════╗

■X25519 ECDH: elliptic curve Diffie-Hellman key exchange; 128-bit security level equivalent

■XChaCha20-Poly1305: authenticated encryption of the message payload with a per-message ephemeral key

■Ed25519 message signing: optional sender authentication; recipient can verify origin without revealing identity to third parties

■Strictly offline: no network calls at any point; key generation and encryption are entirely local

■No metadata: output ciphertext contains no sender identity, timestamp, or content type indicators
