Free Password Hash Generator (Educational)
Hash a password with MD5, SHA-1, or SHA-256 to see what a raw, unsalted hash looks like. This tool is for learning and testing — it is not how real applications should store passwords.
How to Use It
Type a password, pick an algorithm, and the resulting hash is computed live in your browser. Copy the hash to compare against test fixtures or study how hash output changes with the input.
Example
Hashing password123 with SHA-256 always produces the exact same 64-character hex digest — which is precisely why plain hashing alone is unsafe for passwords (see FAQ).
Common Use Cases
- Learning how MD5, SHA-1, and SHA-256 differ in output length and format.
- Generating test fixtures for unit tests that check against a known hash.
- Demonstrating why unsalted password hashing is insecure, in a classroom or workshop.
FAQs
Is this how real systems should store passwords?
No. A plain MD5, SHA-1, or SHA-256 hash of a password is fast to compute — which means an attacker with a leaked database can try billions of guesses per second against it. Real systems must use a slow, purpose-built, salted algorithm like bcrypt, scrypt, or Argon2, which are deliberately expensive to brute-force and include a unique salt per user to defeat precomputed lookup tables. This tool exists purely to show what a raw hash looks like, for learning and testing.
What does "salted" mean?
A salt is random data mixed into the password before hashing, unique per user. It ensures two users with the same password get different hashes, and defeats precomputed "rainbow table" attacks. This tool does not add a salt — it hashes the raw password only, for demonstration purposes.
Is my password uploaded anywhere?
No — hashing happens entirely client-side in your browser. Nothing you type is sent to a server. Still, avoid entering a real password you actually use anywhere else.
