What is required to enable hashing with the DataWeave Crypto module?

• A. Java Keytool generates a keystore file
• B. Mule Crypto processor uses JCE configuration with a generated keystore file
• C. DataWeave hashing requires no keystore
• D. You must purchase a separate cryptography license

Answer: (B)

Hashing with the DataWeave Crypto module hinges on the Java Cryptography Extension (JCE) setup in Mule. The Crypto processor uses the JCE configuration to access cryptographic keys stored in a keystore, so enabling hashing requires configuring JCE and pointing it to a generated keystore file. This keystore holds the keys the JCE provider uses during hashing operations, and without that configuration and keystore, the hashing cannot run. While you might generate a keystore with Java Keytool, that step alone isn’t enough—you must also configure Mule’s JCE to use that keystore. The idea that no keystore is needed or that a separate license is required isn’t accurate.
