This function calculates a keyed hexadecimal hash of a given text value using one of the algorithms listed in the table, below.
| Argument | Type | Description |
|---|---|---|
| algorithm | Text | The method to use to generate the hash from text. See the table below. |
| text | Text | The message data, combined with the key to generate the final hash value. |
| key | Text | The secret key mixed with text to generate the final hash value. |
Return value type: Text.
| Algorithm | Notes |
|---|---|
| md5 | |
| sha1 | |
| sha256 | |
| sha384 | |
| sha512 |
The specified algorithm is used as a Hash-based Message Authentication Code (HMAC). The HMAC process mixes a secret key with the message data, hashes the result with the hash function, mixes that hash value with the secret key again, and then applies the hash function a second time.
Data types other than text are not converted into text automatically. All texts are assumed to have the UTF-8 encoding. The algorithm name is case-insensitive. The key and the value are case-sensitive.
