decrypt function

Uint8List decrypt({ required Uint8List msgToOpen, required Object? msgToAuth, required SecretKey recipient, required Uint8List domain, })

Decrypts a sealed message without verifying the signature.

This allows inspecting the signer before verification. Use signer to extract the signer's fingerprint, then verify or verifyDetached to verify.

• msgToOpen: The serialized COSE_Encrypt0 structure
• msgToAuth: The same additional authenticated data used during sealing
• recipient: The xHPKE secret key to decrypt with
• domain: Application domain for HPKE key derivation

Returns the decrypted COSE_Sign1 structure (not yet verified).

Implementation

Uint8List decrypt({
  required Uint8List msgToOpen,
  required Object? msgToAuth,
  required xhpke.SecretKey recipient,
  required Uint8List domain,
}) => ffi.coseDecrypt(
  msgToOpen: msgToOpen,
  msgToAuth: _encode(msgToAuth),
  recipient: recipient.inner,
  domain: domain,
);
