Enum RecipientInfoKind 

#[non_exhaustive]
pub enum RecipientInfoKind {
    Ktri,
    Kari,
    Kekri,
    Kemri,
    Pwri,
    Ori,
}

How a CMS structure conveys the content-encryption key to its recipient.

The variants are the RecipientInfo CHOICE of RFC 5652 §6.2, plus the KEM alternative RFC 9629 carries inside OtherRecipientInfo.

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.

Ktri

KeyTransRecipientInfo: the CEK is encrypted under the recipient’s public key.

Kari

KeyAgreeRecipientInfo: a shared secret is agreed with the recipient’s key, run through a KDF, and used to wrap the CEK.

Kekri

KEKRecipientInfo: the CEK is wrapped under a previously shared symmetric key.

Kemri

KEMRecipientInfo (RFC 9629), carried as OtherRecipientInfo.

Pwri

PasswordRecipientInfo.

Ori

An OtherRecipientInfo this build does not recognise.
