> PBKDF2 알고리즘의 다양한 구현 방식을 시도해 보았지만, 모두 동일한 해시(Discourse의 것과 다름)를 출력했습니다.

`openssl`의 구현 방식을 시도해 보셨나요? 우리가 사용하는 방식입니다(`discourse/lib/pbkdf2.rb`에서 확인하실 수 있습니다).

예를 들어, 사용자 비밀번호를 `swordfish#`으로 설정한 후:

```plaintext
discourse_development=# select password_hash, salt, password_algorithm from users where id=2;
-[RECORD 1]------+-----------------------------------------------------------------
password_hash | 67650523776bdc87ebcd2fc11719553c87b11e6c4da49806d9d5232460d2adc9
salt | 712ef44dd6fe6d6f0f1b6f702bb78459
password_algorithm | $pbkdf2-sha256$i=600000,l=32$

```

```plaintext
$ openssl kdf \
  -kdfopt pass:'swordfish#' \
  -kdfopt salt:712ef44dd6fe6d6f0f1b6f702bb78459 \
  -kdfopt digest:SHA-256 \
  -kdfopt iter:600000 \
  -keylen 32 \
  PBKDF2 \
  | tr -d : | tr '[:upper:]' '[:lower:]'
