Enum VerificationKeyIndicator 

#[non_exhaustive]
pub enum VerificationKeyIndicator {
    VerificationKey(PublicVerificationKey),
    ReconstructionValue(EccP256CurvePoint),
}

Contains either verification key or reconstruction value depending on certificate type.

Variants

• VerificationKey: For explicit certificates

  • Contains public key for verifying holder’s signatures

• ReconstructionValue: For implicit certificates

  • Contains value for recovering public key (per SEC 4 and 5.3.2)

Critical Information Field

This is a critical information field as defined in 5.2.5:

• An implementation that does not recognize the indicated CHOICE when verifying a signed SPDU shall indicate that the SPDU is invalid (per 4.2.2.3.2)
• Invalid in this context means its validity cannot be established

Canonicalization

Subject to canonicalization for operations specified in 6.1.2:

• Applies to PublicVerificationKey and EccP256CurvePoint
• EccP256CurvePoint must be in compressed form:
  • Choice must be either compressed-y-0 or compressed-y-1

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.

ReconstructionValue(EccP256CurvePoint)

Trait Implementations

impl AsnType for VerificationKeyIndicator

const TAG: Tag = { rasn::types::Tag::EOC }

The associated tag for the type.

const TAG_TREE: TagTree

The root of this type’s tree of tag’s if it a CHOICE type, otherwise its Leaf that points Self::TAG.

const IDENTIFIER: Identifier

Identifier of an ASN.1 type as specified in the original specification if not identical with the identifier of Self

const CONSTRAINTS: Constraints

The set of constraints for values of the given type.

const IS_CHOICE: bool = true

impl Choice for VerificationKeyIndicator

const VARIANTS: &'static [TagTree]
