Parameters that are required to encrypt plaintext 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.

mode: Option<DukptEncryptionMode>

The block cipher mode of operation. Block ciphers are designed to encrypt a block of data of fixed size, for example, 128 bits. The size of the input block is usually same as the size of the encrypted output block, while the key length can be different. A mode of operation describes how to repeatedly apply a cipher's single-block operation to securely transform amounts of data larger than a block.

The default is CBC.

dukpt_key_derivation_type: Option<DukptDerivationType>

The key type encrypted 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 incoming data decryption, outgoing data encryption, or both.

initialization_vector: Option<String>

An input to cryptographic primitive used to provide the intial state. Typically the InitializationVector must have a random or psuedo-random value, but sometimes it only needs to be unpredictable or unique. If you don't provide a value, Amazon Web Services Payment Cryptography generates a random value.

Implementations

impl DukptEncryptionAttributes

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 mode(&self) -> Option<&DukptEncryptionMode>

The block cipher mode of operation. Block ciphers are designed to encrypt a block of data of fixed size, for example, 128 bits. The size of the input block is usually same as the size of the encrypted output block, while the key length can be different. A mode of operation describes how to repeatedly apply a cipher's single-block operation to securely transform amounts of data larger than a block.

The default is CBC.

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

The key type encrypted 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 incoming data decryption, outgoing data encryption, or both.

pub fn initialization_vector(&self) -> Option<&str>

An input to cryptographic primitive used to provide the intial state. Typically the InitializationVector must have a random or psuedo-random value, but sometimes it only needs to be unpredictable or unique. If you don't provide a value, Amazon Web Services Payment Cryptography generates a random value.

impl DukptEncryptionAttributes

pub fn builder() -> DukptEncryptionAttributesBuilder

Creates a new builder-style object to manufacture DukptEncryptionAttributes.

Trait Implementations

impl Clone for DukptEncryptionAttributes

fn clone(&self) -> DukptEncryptionAttributes

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DukptEncryptionAttributes

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

Formats the value using the given formatter.

impl PartialEq for DukptEncryptionAttributes

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