Enum UnauthenticatedRecipientMode 

#[non_exhaustive]
pub enum UnauthenticatedRecipientMode {
    Passphrase,
    PublicKey,
}

Result of a cheap structural probe of an .fcr file’s recipient list.

Not a security claim. probe_recipient_mode performs no KDF, no private-key operation, no credential prompt, no header-MAC verification, and no payload decryption. A positive result is not evidence that the file is authentic, decryptable, untampered, or well-formed beyond the structural shape required to classify it. Use only for UI / routing hints.

For an authenticated mode value — produced only after a recipient unwraps and the header MAC verifies — see AuthenticatedRecipientMode on DecryptOutcome.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Passphrase

File contains exactly one native argon2id recipient and is decrypted with a passphrase.

PublicKey

File contains one or more native x25519 public-key recipients and is decrypted with a matching PrivateKey.
