DataWeave 2.2 is compatible and bundled with Mule 4.2. Standard Support for Mule 4.2 ended on May 2, 2021, and this version of Mule will reach its End of Life on May 2, 2023, 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 value of binary content using a specified algorithm.

The first argument specifies the binary content to use to calculate the hash value, and the second argument specifies the hashing algorithm to use. The second argument must be any of the accepted Algorithm names:

Algorithm names Description


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


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.


Name Description


The binary input content to hash.


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


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


%dw 2.0
import dw::Crypto
output application/json
{ "md2" : Crypto::hashWith("hello" as Binary, "MD2") }


{ "md2": "\ufffd\u0004ls\ufffd\u00031\ufffdh\ufffd}8\u0004\ufffd\u0006U" }
