Detailed Description

Per-key metadata stored alongside encrypted Parquet components.

For INTERNAL mode: key_material contains the raw AES key bytes. For EXTERNAL mode: key_id contains the KMS reference string.

This is serialized into the Parquet ColumnChunk's column_crypto_metadata field so that the decryptor can identify which key to use.

◆ deserialize()

static expected< EncryptionKeyMetadata > signet::forge::crypto::EncryptionKeyMetadata::deserialize	(	const uint8_t *	data,
		size_t	size
	)

inlinestatic

Deserialize from bytes.

Returns an error if the data is malformed.

Parameters

data	Pointer to TLV-serialized bytes.
size	Number of bytes to parse.

Returns: Deserialized metadata, or ENCRYPTION_ERROR if truncated or missing key_mode.

Definition at line 430 of file key_metadata.hpp.

◆ serialize()

std::vector< uint8_t > signet::forge::crypto::EncryptionKeyMetadata::serialize ( ) const

inline

Serialize to bytes using TLV format.

Returns: Serialized byte vector containing all populated fields.
