The crypto.createHmac() method is used to create Hmac instances. Hmac objects are not to be created directly using the new keyword. import { createReadStream } from 'fs'; import { stdout } from 'process'; const { createHmac } = await import('crypto'); const hmac = createHmac('sha256', 'a secret'); const input = createReadStream('test.js'); input.pipe(hmac).pipe(stdout);const { createReadStream, } = require('fs'); const { createHmac, } = require('crypto'); const { stdout } = require('process'); const hmac = createHmac('sha256', 'a secret'); const input = createReadStream('test.js'); input.pipe(hmac).pipe(stdout); const { createHmac } = await import('crypto'); const hmac = createHmac('sha256', 'a secret'); hmac.update('some data to hash'); console.log(hmac.digest('hex')); // Prints: // 7fd04df92f636fd450bc841c9418e5825c17f33ad9c87c518115a45971f7f77econst { createHmac, } = require('crypto'); const hmac = createHmac('sha256', 'a secret'); hmac.update('some data to hash'); console.log(hmac.digest('hex')); // Prints: // 7fd04df92f636fd450bc841c9418e5825c17f33ad9c87c518115a45971f7f77e hmac.digest([encoding])#
