Hash Generator
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from text or files.
How to use
- Paste text or drop a file onto the page.
- Select the hash algorithms you need.
- Click Generate to compute the digests.
- Copy the resulting hashes for verification.
About this tool
Hash Generator computes cryptographic digests for text snippets and files directly in your browser. Developers and administrators use it to verify downloads, generate cache keys, and double-check integrity of deployment artefacts.
Features
Support for MD5, SHA-1, SHA-256, and SHA-512, simultaneous computation across algorithms, drag-and-drop file input, streaming hashing for large files, and copy buttons for every digest. UTF-8 text is handled consistently across platforms.
Use cases
Verifying release artefacts against published checksums, building content-addressable cache keys, detecting file tampering, and providing hashes for vendors who require integrity proofs on uploaded documents.
Why choose this tool
Everything runs locally, so sensitive files never leave your computer. The tool relies on the browser native crypto implementation, which is fast and consistent with hashes produced by command-line utilities like sha256sum.
FAQ
- Which algorithms are supported?
- MD5, SHA-1, SHA-256, and SHA-512 are available, covering the most common integrity-check requirements.
- Is MD5 still safe to use?
- MD5 is suitable for checksums but should not be used for passwords or security-critical signatures due to known collisions.
- Can I hash large files?
- Yes. Files are read in chunks so multi-megabyte inputs can be hashed without running out of memory.
