Struct EnvelopeProof 

pub struct EnvelopeProof {
    pub type: String,
    pub cryptosuite: Option<String>,
    pub verification_method: String,
    pub created: String,
    pub proof_purpose: String,
    pub proof_value: String,
    pub id: Option<String>,
    pub previous_proof: Option<String>,
}

The cryptographic proof block: either a W3C Data Integrity Proof or a detached JWS, per spec §8.2.

Fields

type: String

Always "DataIntegrityProof" for the JCS-canonicalized cryptosuites, or "JsonWebSignature2020" for compact JWS detached.

cryptosuite: Option<String>

Required for DataIntegrityProof — "eddsa-jcs-2022" or "ecdsa-jcs-2019" — and OMITTED, not nulled, for JsonWebSignature2020 (§7.1.11).

skip_serializing_if is load-bearing rather than cosmetic: this member sits inside the §7.2.1 canonicalization base, so emitting "cryptosuite": null would put a member in the SIGNED bytes that an implementer following the spec’s proof table never builds, and no JWS envelope this crate minted would verify anywhere else.

verification_method: String

DID URL referencing the verifying key (e.g., did:key:z6Mk...#z6Mk...).

created: String

RFC 3339.

proof_purpose: String

"assertionMethod" for a principal proof or a lone notary proof; "authentication" for the notary countersignature of a chain (§7.1.11).

proof_value: String

Multibase or base64url-encoded signature bytes.

id: Option<String>

Identifier for this proof, unique within the envelope. REQUIRED when proof is a chain, absent for a lone proof, which links to nothing.

previous_proof: Option<String>

The id of the proof this one countersigns. Present on the notary proof of a chain; absent on the principal proof, its head.
