This object allows you to generate a variety of message digests. The JavaScript equivalent is the Node.js Crypto API.

Object Creation: The hashing algorithm is specified when creating the roHashGenerator object.

CreateObject("roHashGenerator", algorithm As String)

The algorithm parameter accepts the following strings:

  • "SHA256"
  • "SHA384"
  • "SHA512"
  • "SHA1"
  • "MD5"
  • "CRC32"

Note

CRC32 is only available on firmware versions 4.4.x or later.

ifHashGenerator

Hash(obj As Object) As Object

Hashes the payload, which can be supplied in the form of a string (or any object implementing ifString) or an roByteArray. The hash is returned as an roByteArray.

SetHmacKey(key As Dynamic) As Boolean

Supplies a cryptographic key for the hashing function. This method accepts a plain-text key.

SetObfuscatedHmacKey(key As String) As Boolean

Supplies a cryptographic key for the hashing function. This method accepts a key that is obfuscated using a shared secret.

GetFailureReason() As String
