Calculates a secure hash of a field for storing in the event. See hashMatch() on how to search for events using hashes. bits can reduce the width of the output if desired to keep the resulting strings short.
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
| field | string | Yes | The name of the field to hash. | |
| as | string | No | The name of output field, defaults to the input field | |
| replaceInRawstring | bool | No | true | Replace all substrings in @rawstring that has the input value with the hash too. |
| salt | string | Yes | The name of the secret salt to use. | |
| hash | string | No | sha256 | Hash algorithm. Supported: sha256 and sha512. |
| bits | number | No | 256 | Hash algorithm output bits to keep. Must be a multiple of 8 in the range 8 - 512. |
field is the unnamed parameter.
Replace the value in the ssn field with the hash of the existing value, also replacing it in @rawstring
hashRewrite(ssn, salt="salt1")
