Struct aws_sdk_paymentcryptographydata::types::WrappedKey

#[non_exhaustive]
pub struct WrappedKey {
    pub wrapped_key_material: Option<WrappedKeyMaterial>,
    pub key_check_value_algorithm: Option<KeyCheckValueAlgorithm>,
}

Parameter information of a WrappedKeyBlock for encryption key exchange.

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.

wrapped_key_material: Option<WrappedKeyMaterial>

Parameter information of a WrappedKeyBlock for encryption key exchange.

key_check_value_algorithm: Option<KeyCheckValueAlgorithm>

The algorithm that Amazon Web Services Payment Cryptography uses to calculate the key check value (KCV). It is used to validate the key integrity.

For TDES keys, the KCV is computed by encrypting 8 bytes, each with value of zero, with the key to be checked and retaining the 3 highest order bytes of the encrypted result. For AES keys, the KCV is computed using a CMAC algorithm where the input data is 16 bytes of zero and retaining the 3 highest order bytes of the encrypted result.

Implementations

impl WrappedKey

pub fn wrapped_key_material(&self) -> Option<&WrappedKeyMaterial>

Parameter information of a WrappedKeyBlock for encryption key exchange.

pub fn key_check_value_algorithm(&self) -> Option<&KeyCheckValueAlgorithm>

The algorithm that Amazon Web Services Payment Cryptography uses to calculate the key check value (KCV). It is used to validate the key integrity.

For TDES keys, the KCV is computed by encrypting 8 bytes, each with value of zero, with the key to be checked and retaining the 3 highest order bytes of the encrypted result. For AES keys, the KCV is computed using a CMAC algorithm where the input data is 16 bytes of zero and retaining the 3 highest order bytes of the encrypted result.

impl WrappedKey

pub fn builder() -> WrappedKeyBuilder

Creates a new builder-style object to manufacture WrappedKey.

Trait Implementations

impl Clone for WrappedKey

fn clone(&self) -> WrappedKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WrappedKey

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

Formats the value using the given formatter.

impl PartialEq for WrappedKey

fn eq(&self, other: &WrappedKey) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
