pub fn open_multi(
keypair: &KeyPair,
envelope: &MultiRecipientEnvelope,
) -> Result<Vec<u8>>Expand description
Decrypt a multi-recipient envelope with keypair, if it is a recipient.
Every wrap is trial-decrypted; there is no per-recipient identifier on the
wire. Returns Error::DecryptionFailed uniformly if keypair is not a
recipient or the envelope was tampered with.
