function pbkdf2Sync
Usage in Deno
```typescript import { pbkdf2Sync } from "node:node__crypto.d.ts"; ```
pbkdf2Sync(): Buffer
Provides a synchronous Password-Based Key Derivation Function 2 (PBKDF2)
implementation. A selected HMAC digest algorithm specified by `digest` is
applied to derive a key of the requested byte length (`keylen`) from the `password`, `salt` and `iterations`.
If an error occurs an `Error` will be thrown, otherwise the derived key will be
returned as a `Buffer`.
The `iterations` argument must be a number set as high as possible. The
higher the number of iterations, the more secure the derived key will be,
but will take a longer amount of time to complete.
The `salt` should be as unique as possible. It is recommended that a salt is
random and at least 16 bytes long. See [NIST SP 800-132](https://nvlpubs.nist.gov/nistpubs/Legacy/SP/nistspecialpublication800-132.pdf) for details.
When passing strings for `password` or `salt`, please consider `caveats when using strings as inputs to cryptographic APIs`.
```js
const {
pbkdf2Sync,
} = await import('node:crypto');
const key = pbkdf2Sync('secret', 'salt', 100000, 64, 'sha512');
console.log(key.toString('hex')); // '3745e48...08d59ae'
```
An array of supported digest functions can be retrieved using [getHashes](../.././node__crypto.d.ts/~/getHashes).
