Struct DecapsulationKey 

pub struct DecapsulationKey { /* private fields */ }

A KEM secret key, opening blobs with CryptoSystem::hpke_open (DHKEM-X25519 under VLD0, ML-KEM at VLD1). Signing uses SecretKey; under VLD0 this key is derivable from one via CryptoSystem::decapsulation_key_from_signing_secret. A value tagged with the CryptoKind of the cryptosystem it belongs to.

Ordering compares the kind first (by cryptosystem preference) then the value. Parses and displays as kind:value; a bare value with no kind: prefix decodes against the best available kind.
