Applies cryptographic hashing algorithms with Message Authentication signing to text strings. Provide a Hash MAC (Message Authentication Code) Key for an extra level of security. By default, converted strings are converted to hex format and use UTF-8 encoding. To shorten the strings, select the Base 64 checkbox.

1. Not fully supported in calculation rules that have a condition of After Save or the Also Recalculate on Load option selected. It may fail if the rule's field is used in a grid, form, or saved search.

2. Except when this field appears on a form or is triggered by such a field.


Parameter Description
textValue The text data to hashes that result with the hashMAC function.


Hashing algorithm for the function (example: MD5, SHA1, SHA256, SHA512).


Hash function key value.


(Optional) Flag for returning result in base64 format. Default value is false.


(Optional) Flag to specify that key is in base64 format. Default value is false.

Return Value

hashMACText value


$(HashMACtext("Test value", "MD5", "keyValue", false, false))

Returns this value: 10ffe441a1b9db39adb520d9781958db
