Struct MacAlgorithmDukpt

#[non_exhaustive]
pub struct MacAlgorithmDukpt {
    pub key_serial_number: String,
    pub dukpt_key_variant: DukptKeyVariant,
    pub dukpt_derivation_type: Option<DukptDerivationType>,
}

Parameters required for DUKPT MAC generation and verification.

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.

key_serial_number: String

The unique identifier known as Key Serial Number (KSN) that comes from an encrypting device using DUKPT encryption method. The KSN is derived from the encrypting device unique identifier and an internal transaction counter.

dukpt_key_variant: DukptKeyVariant

The type of use of DUKPT, which can be MAC generation, MAC verification, or both.

dukpt_derivation_type: Option<DukptDerivationType>

The key type derived using DUKPT from a Base Derivation Key (BDK) and Key Serial Number (KSN). This must be less than or equal to the strength of the BDK. For example, you can't use AES_128 as a derivation type for a BDK of AES_128 or TDES_2KEY.

Implementations

impl MacAlgorithmDukpt

pub fn key_serial_number(&self) -> &str

The unique identifier known as Key Serial Number (KSN) that comes from an encrypting device using DUKPT encryption method. The KSN is derived from the encrypting device unique identifier and an internal transaction counter.

pub fn dukpt_key_variant(&self) -> &DukptKeyVariant

The type of use of DUKPT, which can be MAC generation, MAC verification, or both.

pub fn dukpt_derivation_type(&self) -> Option<&DukptDerivationType>

The key type derived using DUKPT from a Base Derivation Key (BDK) and Key Serial Number (KSN). This must be less than or equal to the strength of the BDK. For example, you can't use AES_128 as a derivation type for a BDK of AES_128 or TDES_2KEY.

impl MacAlgorithmDukpt

pub fn builder() -> MacAlgorithmDukptBuilder

Creates a new builder-style object to manufacture MacAlgorithmDukpt.

Trait Implementations

impl Clone for MacAlgorithmDukpt

fn clone(&self) -> MacAlgorithmDukpt

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MacAlgorithmDukpt

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

Formats the value using the given formatter.

impl PartialEq for MacAlgorithmDukpt

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

Tests for self and other values to be equal, and is used by ==.

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

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