Free Online Hash Generator
Use this free Hash Generator to create MD5, SHA-1, SHA-256, SHA-384, SHA-512, and HMAC hashes from text or files. Paste text, upload a file, choose the algorithms you need, and copy the generated hash values instantly.
Hash tools are useful for checksums, file integrity checks, API signatures, debugging webhook payloads, comparing generated outputs, and creating deterministic identifiers for non-secret data.
The tool runs in your browser with no login required. Text and file hashing are processed locally, so you can generate copyable hashes without sending content through an account-based service.

Hash Generator FAQ
What is a hash generator?
A hash generator turns input data into a fixed-length value using an algorithm such as MD5, SHA-256, or SHA-512. Hashes are commonly used for checksums, comparisons, and integrity checks.
Can I hash files with this tool?
Yes. You can select a file and generate hash values for its contents directly in your browser.
What is the difference between a hash and HMAC?
A normal hash uses only the input data. HMAC uses both the input data and a secret key, which makes it useful for signatures and webhook verification workflows.
Should I use MD5 for security?
No. MD5 is useful for legacy checksums but should not be used for modern security. Prefer SHA-256, SHA-512, or HMAC-based workflows when security matters.
Is my text or file uploaded?
No. Hashing runs in your browser and does not require login.
