About This Tool & Technical Logic
A hash is a one-way fingerprint: fixed-length output, deterministic, and infeasible to reverse. This tool computes every supported algorithm simultaneously so you can compare — MD5 (128-bit, broken for security), SHA-1 (160-bit, broken), the SHA-2 family (the current standard), SHA-3 (the backup standard), and RIPEMD-160.
bcrypt is different: a deliberately slow, salted password hash with a cost factor, stored in a self-describing modular crypt string. Passwords should always use bcrypt (or argon2), never raw MD5/SHA — speed is the enemy when defending against offline guessing.
crypto-js digests (MD5, SHA*, RIPEMD160) + bcryptjs with cost 10; digest rendered as lowercase hex.
How to Use — Step by Step
- 1
Choose the right algorithm
File integrity checks: any. Legacy compatibility: MD5/SHA-1. New designs: SHA-256+. Passwords: bcrypt only.
- 2
Verify with hex output
Compare the digest against a published checksum to confirm a file or message hasn't been altered.
- 3
For passwords, copy the bcrypt string
It embeds salt and cost — generate a fresh one per password; identical inputs yield different bcrypt outputs by design.
Frequently Asked Questions
Collisions — two different inputs with the same MD5 — can be manufactured in seconds on a laptop. Fine for checksums, fatal for signatures.
