com.roma.apic.livedata.common.v1.AesUtils

Description

This class is used to provide the AES encryption and decryption methods.

Example

Encryption:

importClass(com.roma.apic.livedata.common.v1.AesUtils);
function execute(data) {
  var plainText = "plainText";
//Hard-coded encryption and decryption keys pose higher security risks. You are advised to store the key in the configuration file. This example uses the secretKey configured for the custom backend.
  var secretKey = "#{secretKey}";
  var initialVector = "initialVector";
  var encryptText = AesUtils.encrypt(plainText, secretKey, initialVector, AesUtils.KEYLENGTH.KL_128, AesUtils.MODE.GCM, AesUtils.PAD.NOPADDING);
  return encryptText
}

Decryption:

importClass(com.roma.apic.livedata.common.v1.AesUtils);
function execute(data) {
  var encryptText = "encryptText";
//Hard-coded encryption and decryption keys pose higher security risks. You are advised to store the key in the configuration file. This example uses the secretKey configured for the custom backend.
  var secretKey = "#{secretKey}";
  var initialVector = "initialVector";
  var decryptText = AesUtils.decrypt(encryptText, secretKey, initialVector, AesUtils.KEYLENGTH.KL_128, AesUtils.MODE.GCM, AesUtils.PAD.NOPADDING);
  return decryptText
}

Method List

Method Details

• public static java.lang.String decrypt(java.lang.String encryptText, java.lang.String secretKey)

  Decrypting ciphertext using the AES algorithm and a private key

  Input Parameters

  • encryptText: ciphertext to be decrypted (a maximum of 8192 characters).
  • secretKey: secret key.

  Returns

  Decrypted data

• public static java.lang.String encrypt(java.lang.String plainText, java.lang.String secretKey)

  Encrypting plaintext using the AES algorithm and a private key

  Input Parameters

  • plainText: plaintext to be encrypted (a maximum of 4096 characters).
  • secretKey: secret key.

  Returns

  Encrypted data

• public static java.lang.String decrypt(java.lang.String encryptText, java.lang.String secretKey, java.lang.String initialVector, AesUtils.KEYLENGTH length, AesUtils.MODE mode, AesUtils.PAD pad)

  Decrypting ciphertext using the AES algorithm and a private key with mode and length specified.

  Input Parameters

  • encryptText: ciphertext to be decrypted (a maximum of 8192 characters).
