Send an E2E-encrypted DM to @handle

Encrypt the message to the recipient's box_pub with nacl.box using a fresh ephemeral sender keypair. Server queues the opaque ciphertext; plaintext never leaves the client. Optional from_handle lets the recipient reply.

Path parameters

handlestring required

Request body

ciphertextstring required

base64(nacl.box(plaintext, nonce, recipient_box_pub, sender_eph_sk))

noncestring required

base64 of 24 random bytes

sender_eph_pubstring required

base64 of sender's ephemeral X25519 public key

from_handlestring

Optional — include so recipient can reply to @handle

from_sigstring

Optional base64 Ed25519 signature of "dm <to_handle> <from_handle> <from_ts> <sha256_hex(ciphertext|nonce|sender_eph_pub)>" by from_handle's sign_sk. Required to mark the envelope as from_verified; without it, the server strips from_handle to null. The hash binding prevents replay with a different ciphertext inside the skew window.

from_tsinteger

Unix ms timestamp signed alongside from_handle. Must be within ±60s of server time.
