Struct EncryptedParamMetadata 

pub struct EncryptedParamMetadata {
    pub base_type_info: TypeInfo,
    pub algorithm_id: u8,
    pub encryption_type: EncryptionTypeWire,
    pub database_id: u32,
    pub cek_id: u32,
    pub cek_version: u32,
    pub cek_md_version: u64,
    pub normalization_rule_version: u8,
}

Always Encrypted cipher metadata, written after an encrypted parameter’s ciphertext value (MS-TDS 2.2.6.6 CryptoMetadata).

It tells the server how to validate and route the encrypted value: the plaintext column type (BaseTypeInfo), the AEAD algorithm and encryption mode, which column encryption key, and the normalization rule version.

Fields

base_type_info: TypeInfo

Type info of the plaintext column (the BaseTypeInfo).

algorithm_id: u8

Encryption algorithm ID (2 = AEAD_AES_256_CBC_HMAC_SHA256).

encryption_type: EncryptionTypeWire

Deterministic or randomized encryption.

database_id: u32

Database ID of the column encryption key.

cek_id: u32

Column encryption key ID.

cek_version: u32

Column encryption key version.

cek_md_version: u64

Column encryption key metadata version.

normalization_rule_version: u8

Normalization rule version applied to the plaintext.

Implementations

impl EncryptedParamMetadata

pub fn encode(&self, buf: &mut BytesMut)

Encode the cipher-metadata trailer to the buffer, in the order the server expects it after the ciphertext value.

Trait Implementations

impl Clone for EncryptedParamMetadata

fn clone(&self) -> EncryptedParamMetadata

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EncryptedParamMetadata

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
