Function pbkdf2

pbkdf2(password, salt, iterations, keyLen, algorithm): Buffer
Pbkdf2 algorithm
Parameters
- password: Buffer
  Key. This is sensitive information. Do not write it in plaintext in the source code.
- salt: Buffer
  Salt value. Note: For security purposes, the salt length should be greater than 8 bytes, and the salt should be a secure random number.
- iterations: number
  Dieda number. Note: More than 1000 iterations are recommended.
- keyLen: number
  Length of the generated hash key. Note: The length is less than 32 bytes, which may be insecure in some cases.
- algorithm: string
  Indicates the hash algorithm name.
Returns Buffer
Example
```
import * as crypto from 'crypto';
import * as buffer from 'buffer';

let password = buffer.from("**********");
let salt = buffer.from("***********");

let crypt = crypto.pbkdf2(password, salt, 1000, 32, crypto.Hashs.SHA1);
console.log(crypt.toString(buffer.Encoding.Base64));
```
