HMACBinary

DataWeave 2.2 is compatible and bundled with Mule 4.2. This version of Mule reached its End of Life on May 2, 2023, when Extended Support ended.

Deployments of new applications to CloudHub that use this version of Mule are no longer allowed. Only in-place updates to applications are permitted.

MuleSoft recommends that you upgrade to the latest version of Mule 4 that is in Standard Support so that your applications run with the latest fixes and security enhancements.

HMACBinary(Binary, Binary, String): Binary

Computes an HMAC hash (with a secret cryptographic key) on input content.

See also, HMACWith.

Parameters

Name Description

secret

The secret cryptographic key (a Binary) used when encrypting the content).

content

The input content, a Binary value.

algorithm

The hashing algorithm. HmacSHA1 is the default. Valid values depend on the JDK version you are using. For JDK 8 and JDK 11, HmacMD5, HmacSHA1, HmacSHA224, HmacSHA256, HmacSHA384, and HmacSHA512 are valid algorithms. For JDK 11, HmacSHA512/224 and HmacSHA512/256 are also valid.

Example

This example uses HMAC with a secret value to encrypt the input content.
