If you configure this field, the decryption algorithm expects the IVs to be added to the beginning of the ciphertext during decryption. Follow these steps for the configuration: 1. In Anypoint Studio, drag a Cryptography Module operation to your flow, for example **Jce sign**. 2. Select the operation from the flow. 3. In the operation configuration screen, click the plus sign to access the module global configuration. 4. In the **Global Element Properties** window, enable the **Use random IVs** field. ![A configuration setting for Crypto JCE with options for keystore and random IV usage](/mulesoft/current/en-us/cryptography-module/2.0/_images/crypto-random-iv.png) In the **XML editor** window, the configuration looks like this: ```xml crypto:jce-config name="Crypto_Jce" doc:name="Crypto Jce" keystore="/Users/MuleSoft/Desktop/jcekeystore.jks" password="mulesoft" useRandomIVs="true"> ``` ## See Also - [Cryptography Module Examples](https://docs.mulesoft.com/cryptography-module/2.0/cryptography-module-examples) - [Cryptography Module Reference 2.0](https://docs.mulesoft.com/cryptography-module/2.0/cryptography-module-reference)
