Struct DukptDerivationAttributes

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

Parameters required for encryption or decryption of data using DUKPT.

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_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

dukpt_key_variant: Option<DukptKeyVariant>

The type of use of DUKPT, which can be for incoming data decryption, outgoing data encryption, or both.

Implementations

impl DukptDerivationAttributes

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_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

pub fn dukpt_key_variant(&self) -> Option<&DukptKeyVariant>

The type of use of DUKPT, which can be for incoming data decryption, outgoing data encryption, or both.

impl DukptDerivationAttributes

pub fn builder() -> DukptDerivationAttributesBuilder

Creates a new builder-style object to manufacture DukptDerivationAttributes.

Trait Implementations

impl Clone for DukptDerivationAttributes

fn clone(&self) -> DukptDerivationAttributes

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DukptDerivationAttributes

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

Formats the value using the given formatter.

impl PartialEq for DukptDerivationAttributes

fn eq(&self, other: &DukptDerivationAttributes) -> 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.
