What this tool does
Analyzes password hashes produced by bcrypt or scrypt and surfaces parameters like cost/work factor.
This page focuses on practical, step‑by‑step usage for **Bcrypt & Scrypt Analyzer**, with clear examples and common pitfalls.
When you should use it
Use it when auditing password storage, migrating auth systems, or verifying that your cost settings are sensible.
How to use
- Paste the hash string.
- The tool detects the scheme and parameters.
- Compare cost factors against your security requirements.
Quick example
Example: Inspect a bcrypt hash and confirm the cost is set to 12 (or higher, depending on your threat model).
Notes
Never paste real production password hashes you can’t disclose; use test data where possible.

About Bcrypt & Scrypt
Bcrypt and Scrypt are modern password hashing algorithms designed specifically to protect against brute-force attacks. They incorporate work factors that make hashing computationally expensive, slowing down potential attackers.
Bcrypt Features
- Adaptive cost factor for increasing security over time
- Built-in salt generation
- Resistant to GPU and ASIC attacks
- Widely adopted in web applications
Scrypt Features
- Memory-hard algorithm
- Excellent resistance to hardware attacks
- Used in cryptocurrency (Litecoin)
- Configurable memory and CPU cost
FAQ
Is Bcrypt & Scrypt Analyzer encryption?
No. It is primarily an analysis/encoding utility. If you need confidentiality, use a real encryption scheme and manage keys properly.
What should I do if the input fails to decode/parse?
Start by checking for missing padding, wrong alphabet/variant, or extra whitespace. If the data looks multi-layered, try decoding step-by-step (e.g., URL decode → Base64 decode).
Is it safe to paste sensitive data here?
For best security, avoid pasting real secrets (private keys, live tokens, seed phrases). Use test data or work offline, especially for anything that could grant access or move funds.
