fn seal_blob_content(
blob: CipherBlobV1,
cipher_key: SymmetricKeySlotId,
ctx: &mut KeyStoreContext<'_, KeySlotIds>,
) -> Result<String, BlobEncryptionError>Expand description
Seals a constructed CipherBlobLatest under cipher_key, returning the
opaque string form. Shared by all CipherBlobLatest producers so they
don’t each re-implement the versioned-enum wrap + COSE seal + base64 chain.
