Cards API

Retrieve Card Data | Additional Method

This is a web service designed to retrieve the card data required for completing e-commerce payments — PAN, CVC2/CVV2, expiry date of the card can be retrieved. The returned payload is encrypted with an asymmetric public key; this enables end-to-end encryption to the card holder device. The parameters that were included in the request are only returned. The caller is responsible of validating the integrity of the public key.

Send a request to this endpoint, if you are not using the Enfuce BIN sponsorship.
Retrieving card data through this endpoint implies PCI DSS compliance of the client with the Scheme. An easier method that you can use is the Initiate Card Data Retrieval endpoint — this endpoint enables rendering of card information to the cardholder’s device without requiring compliance of the client with PCI DSS.

Example:

// ...

import java.security.KeyFactory;
import java.security.PrivateKey;
import java.security.spec.PKCS8EncodedKeySpec;
import java.util.Base64;
import javax.crypto.Cipher;

// ...


## Example of decrypting an encrypted field

```java
private String decrypt(String data, String privKeyPEM) throws Exception {


## Example of preparing the key

```java
  String privKeyString = privKeyPEM.replaceAll("\\n", "").replace("-----BEGIN PRIVATE KEY-----", "").replace("-----END PRIVATE KEY-----", "");
  byte[] encodedKey = Base64.getDecoder().decode(privKeyString);
  PKCS8EncodedKeySpec spec = new PKCS8EncodedKeySpec(encodedKey);
  KeyFactory kf = KeyFactory.getInstance("RSA");
  PrivateKey privateKey = kf.generatePrivate(spec);


 ## Example of preparing the decryption

  ```java
  Cipher cipher = Cipher.getInstance("RSA/ECB/OAEPWithSHA-256AndMGF1Padding");
  cipher.init(Cipher.DECRYPT_MODE, privateKey);


## Example of preparing the data

 ```java
 byte[] cryptogram = Base64.getDecoder().decode(data);


## Example of decryption

 ```java
 byte[] decryptedBytes = cipher.doFinal(cryptogram);
return new String(decryptedBytes);
