このツールの使い方

1. 1

   Type or paste the password you want to hash.

2. 2

   Optionally set a salt (leave it blank for a secure random one) and choose an iteration count.

3. 3

   Click Hash. The salted PBKDF2-SHA256 digest is derived entirely in your browser.

パスワードハッシュジェネレーター（PBKDF2）とは何ですか？

よくある活用例

• Learn how salted, iterated password hashing works by watching the output change with the salt and work factor.

• Generate test hashes to seed a development database without wiring up your real auth code.

• Produce a reference digest to confirm your server-side PBKDF2 implementation matches for the same inputs.

• Demonstrate to a team why MD5/SHA-1 password storage is unsafe versus a deliberately slow KDF.

• Create a one-off credential for a script or prototype where pulling in a full auth library is overkill.

• Benchmark how iteration count affects hashing time on your hardware to pick a sensible work factor.
