hashWith

DataWeave 2.1 is compatible with Mule 4.1. Standard Support for Mule 4.1 ended on November 2, 2020, and this version of Mule will reach its End of Life on November 2, 2022, when Extended Support ends.

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.

hashWith(Binary, String): Binary

Computes the hash of binary content with a specified algorithm.

You can use these names as algorithm arguments:

Name Description

MD2

The MD2 message digest algorithm as defined in RFC 1319[http://www.ietf.org/rfc/rfc1319.txt].

MD5

The MD5 message digest algorithm as defined in RFC 1321[http://www.ietf.org/rfc/rfc1321.txt].

SHA-1, SHA-256, SHA-384, SHA-512

Hash algorithms defined in the FIPS PUB 180-2 [http://csrc.nist.gov/publications/fips/index.html]. SHA-256 is a 256-bit hash function intended to provide 128 bits of security against collision attacks, while SHA-512 is a 512-bit hash function intended to provide 256 bits of security. A 384-bit hash may be obtained by truncating the SHA-512 output.

Parameters

Name Description

content

A binary input value to encrypt.

algorithm

The name of the algorithm to use for encrypting the content. This value is a String. Defaults to SHA-1.

Example

This example uses the MD2 algorithm to encrypt a binary value.

Source
