API

function hmac_sha256

Performs a HMAC SHA256 hash.

| Parameter | Type | Description | | :-------- | :--------- | :------------ | | data | Uint8Array | Data to hash. | | key | Uint8Array | Secret key. |

Returns: Uint8Array — The HMAC-SHA256 data.

Examples

How to use.

const data = Uint8Array.from([104, 101, 108, 108, …])
const key =  Uint8Array.from([193, 208, 122, 108, …])

hmac_sha256(data, key).then(console.log)

The logged output is UintArray([43, …])
