Wrapped key material
Key Material
Symmetric credential keys delivered to the wallet platform in encrypted form, never as plaintext. Each wallet has a published key-wrapping spec the issuer must follow. The wallet's key-management infrastructure decrypts internally; the issuer never has access to the unwrapping key.
