     * PBKDF2 key derivation function as defined by RSA's PKCS #5: https://www.ietf.org/rfc/rfc2898.txt
     * $algorithm - The hash algorithm to use. Recommended: SHA256
     * $password - The password.
     * $salt - A salt that is unique to the password.
     * $count - Iteration count. Higher is better, but slower. Recommended: At least 1000.
     * $key_length - The length of the derived key in bytes.
     * $raw_output - If true, the key is returned in raw binary format. Hex encoded otherwise.
     * Returns: A $key_length-byte key derived from the password and salt.
