Enum KeyEncryptionKeySource 

pub enum KeyEncryptionKeySource<'a> {
    Encapsulation(&'a EncapsulationMechanism),
    Direct,
    Encrypted(&'a EncryptedKey),
    Agreement(&'a AgreementMethod),
    Derived(&'a DerivedKey),
}

Supplies a content-encryption key for parsed XMLEnc data. A source resolved for a wrapping algorithm. Its output is never implicitly treated as a CEK or exported from a non-exportable provider handle.

Variants

Encapsulation(&'a EncapsulationMechanism)

Experimental KEM producing this operation’s wrapping key.

Direct

Application-owned key material without transported establishment hints.

Encrypted(&'a EncryptedKey)

A key transporting this operation’s wrapping key.

Agreement(&'a AgreementMethod)

Agreement producing this operation’s wrapping key.

Derived(&'a DerivedKey)

Derivation producing this operation’s wrapping key.
