Struct PublicKeyInfo 

#[non_exhaustive]
pub struct PublicKeyInfo {
    pub verifying_key_hex: String,
    pub revoked: bool,
    pub algorithm: KeyAlgorithm,
}

A key’s public half plus its revocation state, read directly from the stored record’s plaintext verifying_key_hex/revoked fields — no private-key decryption involved. For callers (like the did:web document builder in dpp-vc) that only ever need the public key, this avoids an AES-GCM decrypt per key on every call.

algorithm travels with the key because a reader cannot otherwise know how to represent it: the DID-document builder needs it to choose the JWK shape, and guessing is how a key ends up published under the wrong kty.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

revoked: bool
