Hash Type Identifier
Identify the algorithm behind an unknown hash string. Recognises MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, bcrypt, Argon2, PBKDF2, NTLM and 20+ more by length and character set.
Data handling: Processing: this tool runs in your browser and does not send entered data to a tool-service endpoint. Site analytics, advertising, or embedded resources may still make separate requests. See the Privacy Policy for site-level details.
About Hash Type Identifier
In practical terms, Hash Type Identifier identify the algorithm behind an unknown hash string. Recognises MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, bcrypt, Argon2, PBKDF2, NTLM and 20+ more by length and character set. Using it is a three-step job: 1) Open Hash Type Identifier and review the inputs, units, and data-handling notice shown on its page, 2) Enter the information requested by this tool and adjust only the options that apply to your task, 3) Review the result and use the available copy, download, or reset controls. Processing depends on the specific operation. Any external lookup or service should be identified near the tool controls.
Hash Type Identifier is a free, browser-based hash identifier from ProfitTool. Identify the algorithm behind an unknown hash string. Recognises MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, bcrypt, Argon2, PBKDF2, NTLM and 20+ more by length and character set. Review any usage notes shown on this page before relying on its availability. Review the tool's data-handling notice before entering sensitive information; some features store settings locally or contact external services.

Common Mistakes to Avoid
Substituting characters and calling it strong
P@ssw0rd1 is on every cracking list. Randomness beats cleverness every time.
Storing generated secrets in notes apps
Use a real password manager with encryption at rest.
Reusing one strong password everywhere
One breach then exposes every account. Unique per site, always.
Pairs naturally with the DKIM Record Checker — try htpasswd Generator to finish the job.
Key Terms Explained
- Entropy
- A measure of unpredictability in bits. Each extra bit doubles the guessing effort; 80+ bits is a sensible floor.
- Passphrase
- Several random words joined together — easier to type and remember than a short random string, and usually stronger.
- Hashing
- A one-way transform of data. Unlike encryption, it cannot be reversed.
- Credential stuffing
- Attackers replaying username/password pairs leaked from one site against many others.
Data Handling
Data handling depends on this tool's implementation. Read the Data handling notice above the tool before entering sensitive information. Some features run locally; others contact named providers or ProfitTool services. Site analytics, advertising, and embedded resources may also make separate requests.
Why this matters
Weak, reused credentials remain the leading cause of account takeover. Generating genuinely random secrets and understanding how strong they actually are is the highest-leverage security habit available to a non-specialist.
Frequently Asked Questions
Is anything I enter into Hash Type Identifier sent over the internet?›
Do not enter a live password, key, or token unless you have checked the tool's data-handling notice and verified its behavior.
Can I use Hash Type Identifier for commercial or client work?›
Yes. Output from this security tool is yours to use commercially, with no attribution requirement and no licence to buy.
How strong should my output be?›
For anything valuable, aim for at least 16 characters with mixed classes, or a four-plus-word passphrase, and store it in a password manager.
What should I do if Hash Type Identifier gives an unexpected result?›
Re-check your input formatting first, then reload the page to clear any stale state. If it persists, send us the input through the suggestion form and we'll fix it.
Can I trust a browser-based hash identifier?›
Read the Data handling notice above the tool to see whether inputs stay local or are sent to a provider.
Are there related security tools I should use alongside it?›
Yes — the related-tools panel on this page links the utilities most people open right before or after Hash Type Identifier, so you can chain them into one workflow.
Should I reuse results across accounts?›
Never. Generate a fresh value per account so a single breach cannot cascade into your other logins.
Is Hash Type Identifier free to use?›
Yes — Hash Type Identifier is completely free with no signup, watermark, trial or hidden paywall, however often you use it.
