Interface: DecryptionHandler

Example

A sample implementation and usage of the sap.ve.dvl.DecryptionHandler interface with the asmCrypto library.

  ...
  <script src="http://vibornoff.com/asmcrypto.js"></script>
  ...
  var decryptionHandler = {
      deriveKey: function(salt, password) {
          try {
              return asmCrypto.PBKDF2_HMAC_SHA256.bytes(password, salt, 10000, 16);
          } catch (ex) {
              return null;
          }
      },
      decrypt: function(key, iv, input) {
          try {
              return asmCrypto.AES_CBC.decrypt(input, key, true, iv);
          } catch (ex) {
              return null;
          }
      }
  };

  var dvl = ...
  dvl.Client.setDecryptionHandler(decryptionHandler);
