This is only relevant if you are using Typescript, which the OP did not indicate. – lbragile Apr 09 '21 at 23:01
@Ibragile, Angular uses TypeScript by default, so is implied by the OP – SteveC Jul 24 '23 at 08:18

Per the author on npm , The crypto package is no longer available as it is now built in to Node.js. I would suggest looking for an alternative. I came across a Github Gist that contains some suggestions: https://gist.github.com/jo/8619441

Make sure whatever you pick is useable in the browser. Some of the options listed there are server-side only.

Make sure that you install 'crypto' module from npm

use: npm i crypto to install this module.

for more information please visit here.

If this is still not working then you have to check for alternative module because this module is dedicated you can check this
