Crypto: Hash Node

The Crypto: Hash Node allows you to create a cryptographic hash and put it on your payload.

Crypto: Hash Node

Node Properties​

The Crypto: Hash Node's configuration is broken up into two sections ...

Configuration​

First, define the data to encode, the secret to use for hashing, and options for the encoding:

  • Data Template: (Required) A string template that is the input data (or message) used to create the hash.
  • Data Encoding: The encoding of the provided data. By default UTF-8 is selected.
  • Secret Template: A string template, that when provided will be used to create an HMAC digest, instead of a straight hash of the provided data.
  • Secret Encoding: The encoding of the provided secret. By default UTF-8 is selected.
  • Algorithm Type: (Required) The algorithm that is used to generate the hash. Options are:

Note: For Edge Workflows, the data and secret encoding options are only available in GEA version 1.32.0 or higher. In previous GEA versions, both the data and secret are assumed to be encoded as UTF-8.

Result Path​

Next, define where to place the hashed data on the payload:

  • Hash Encoding: The encoding the hash digest should be formatted in. By default Hex is selected.
  • Destination Path: (Required) A payload path to store the hash on the payload, e.g. data.hash.

Node Example​

Given a Crypto: Hash Node with the following configuration ...

  • Data Template: {{working.myData}}
  • Data Encoding: UTF-8
  • Secret Template: {{globals.mySecret}}
  • Secret Encoding: UTF-8
  • Algorithm Type: SHA256
  • Hash Encoding: Hex
  • Destination Path: working.hashedData

... and a payload of the following ...

{
  "working": {
    "myData": "Please Hash Me!"
  },
  "globals": {
    "mySecret": "ThisIsMySuperSecret?!"
  }
}

... the following would be placed on the payload at the path of working.hashedData:
