Key Takeaways
- This is a fully client-side suite: passwords use the browser Web Crypto API (crypto.getRandomValues) and bcrypt runs locally via bcryptjs, so your values are never sent to a server.
- Hashes are not interchangeable - use bcrypt (with a cost factor, 10 is the common default) for storing user passwords, and fast MD5, SHA-1, SHA-256 or SHA-512 only for checksums and file integrity, not password storage.
- To reach a Strong rating, set the length to 16 or more and enable all four character types (uppercase, lowercase, numbers and symbols) together; you can generate up to 20 passwords at once.
- bcrypt is intentionally slow and a higher cost factor takes several seconds in your browser, while the verifier accepts PHP password_hash and Laravel output for debugging logins.
How to Generate and Hash a Secure Password
Set length and character types
Drag the length slider and toggle uppercase, lowercase, numbers and symbols. Each generated value gets a Weak, Fair, Good or Strong rating based on its length and the variety of character classes it contains.
Generate and copy
Set how many passwords you want (up to 20) and click Generate. Every value is produced with the browser Web Crypto API (crypto.getRandomValues), and the Copy button next to each row places it on your clipboard.
Hash or verify if needed
Paste any value into the Hash Generator to see its MD5, SHA-1, SHA-256 and SHA-512 output instantly, create a bcrypt hash with a chosen cost factor, or use the verifier to confirm a plain value matches an existing hash.
Which Hash Algorithm to Use
This tool computes MD5, SHA-1, SHA-256, SHA-512 and bcrypt. They are not interchangeable: fast hashes suit checksums, while a deliberately slow function suits stored passwords. Use this table to match the algorithm to the job.
| Algorithm | Output length | Speed | Best for | Avoid for |
|---|---|---|---|---|
| MD5 | 32 hex chars | Very fast | Legacy checksums, file fingerprints, test data | Storing passwords (broken) |
| SHA-1 | 40 hex chars | Very fast | Legacy integrity checks, Git-style identifiers | Collision-sensitive use |
| SHA-256 | 64 hex chars | Fast | File integrity, checksums, signatures | Direct password storage |
| SHA-512 | 128 hex chars | Fast | Strong integrity checks on large data | Direct password storage |
| bcrypt | 60 chars with salt | Slow (tunable) | Storing user passwords, PHP and Laravel hashes | Quick checksums or large files |
Which Part of the Tool Fits Your Task
You need a strong password
Use the Password Generator. Pick a length of 16 or more, enable all four character types, and watch for the Strong rating. The Web Crypto API supplies the randomness.
You are checking a file or checksum
Use the Hash Generator. Paste the text and read off the MD5, SHA-1, SHA-256 or SHA-512 value, then compare it against the checksum the source published.
You are storing passwords in a database
Use the bcrypt generator. Set a cost factor (10 is the common default), generate the hash, and store the full $2 string. bcrypt is built to be slow against brute force.
You are debugging a login
Use the verifier. Paste the plain text and the hash, pick the algorithm, and confirm whether they match. The bcrypt verifier accepts PHP password_hash and Laravel output.
Common Problems and Fixes
The Copy button does not seem to work
Clipboard access requires a secure context. Make sure you are on the https page and that your browser has not blocked clipboard permission for the site, then click Copy again. The button shows Copied when it succeeds.
My password is rated only Weak or Fair
The rating rises with length and character variety. Increase the length to 12 or more and enable uppercase, lowercase, numbers and symbols together. With all four classes at 16 characters or more you reach Strong.
bcrypt hashing takes several seconds
That is expected. bcrypt is intentionally slow, and a higher cost factor multiplies the time. Cost 4 is near instant for testing, while 12 to 14 can take several seconds because all of the work runs in your browser.
A SHA hash will not verify even though it looks right
Confirm you selected the matching algorithm pill (MD5, SHA-1, SHA-256 or SHA-512). Hashes are compared in lowercase, so case is handled, but a trailing space or a different input encoding will produce a different digest.
Password Generator & Hash Tool - Free & Private
This free tool combines a secure random password generator with a complete hash toolkit. You can generate MD5, SHA-1, SHA-256, SHA-512 and bcrypt hashes, and verify them - all inside your browser with zero data sent to any server.
Frequently Asked Questions
How does the password generator work?
The password generator uses the browser's native Web Crypto API (crypto.getRandomValues) to produce cryptographically secure random values - the same standard used by operating systems and security software.
You can control the length (8-128 characters), and toggle uppercase letters, lowercase letters, numbers and symbols. A strength indicator rates each generated password.
Generate up to 20 passwords at once and copy any of them with a single click.
What is the difference between MD5, SHA-256 and bcrypt?
MD5 and SHA produce a fixed-length fingerprint of any input. They are fast by design and used for file integrity checks, checksums, and non-security-critical identifiers. SHA-256 and SHA-512 are far more collision-resistant than MD5.
bcrypt is a password hashing function intentionally designed to be slow. Its cost factor controls how long hashing takes, making brute-force attacks computationally expensive even with modern hardware.
For storing user passwords in a database, always use bcrypt, Argon2 or scrypt - never raw MD5 or SHA.
What is a bcrypt hash and where is it used?
bcrypt is the default password hashing algorithm in PHP (password_hash), Laravel, Ruby on Rails, Node.js (bcryptjs/bcrypt), Django (with bcrypt backend), and many other frameworks.
A bcrypt hash starts with $2b$10$ followed by 53 characters of salt and hash. The number after $2b$ is the cost factor that controls how slow the hashing is.
This tool generates valid bcrypt hashes with cost 4-14. Cost 10 is the default recommended value for most applications.
Can I verify a PHP password_hash output here?
Yes. PHP password_hash with PASSWORD_DEFAULT or PASSWORD_BCRYPT produces $2y$ or $2b$ hashes that are fully compatible with this verifier.
Paste the plain text password in the plain text field and the hash in the hash field, then click Verify Hash to instantly confirm if they match.
This is useful for debugging login issues, confirming test credentials, or checking hash values stored in a database.
Is my data safe? Does anything get sent to a server?
Browser-side hashing, password generation, and verification can run locally using JavaScript. Avoid entering sensitive data unless local processing is clearly shown.
You can safely paste real passwords and hashes - nothing is logged, stored or transmitted. You can even disconnect from the internet after the page loads and the tool will still work.
The bcrypt library is loaded from a trusted CDN (jsDelivr) the first time you visit, then cached by your browser.
What is the MD5 hash tool for?
MD5 is widely used for checksums, file integrity verification, and legacy database lookup. Many older systems still store MD5 hashes of passwords or files.
Type or paste any text and the tool instantly shows its MD5, SHA-1, SHA-256 and SHA-512 hash - useful for comparing checksums, reverse-engineering legacy systems, or generating test data.
Do not use MD5 for new password storage - it is considered cryptographically broken for that purpose.
What cost factor should I use for bcrypt?
The default cost factor of 10 takes roughly 100-300ms to hash on modern hardware, which is the recommended balance between security and user experience for most web applications.
As hardware gets faster, you can increase the cost. Cost 12 is a good choice for applications where you can afford slightly longer login times. Avoid going below 10 for production use.
In this tool you can set cost from 4 (very fast, for testing) to 14 (very slow, maximum security). Higher cost values will take several seconds to complete in the browser.
Can I use the hash verifier for SHA hashes from other tools?
Yes. The hash verifier supports MD5, SHA-1, SHA-256 and SHA-512 hashes generated by any tool - openssl, Linux sha256sum, online tools, or your own code.
Select the correct algorithm pill (MD5 / SHA-1 / SHA-256 / SHA-512), paste the plain text and the expected hash, and the result shows immediately.
Hashes are compared in lowercase so letter case differences in the hash string are handled automatically.
