Hash Generator
Generate MD5 and SHA digests from text locally in your browser
MD5 and SHA-1 are provided for checksums and legacy compatibility — do not use them for password storage or security-sensitive integrity checks. Prefer SHA-256 or stronger.
Accepted upload: .txt · max 5 MB. Hashes are computed locally with Web Crypto (MD5 runs in-browser).
Input
Hashes update as you type — or press Generate
Hash comparison
MD5, SHA-1, SHA-256, SHA-384, and SHA-512

Enter text or load the sample to generate digests for all supported algorithms.
Frequently asked questions
Common questions about the Hash Generator.
How does Hash Generator work?
Enter or upload text and generate digests. ToolsArk computes MD5, SHA-1, SHA-256, SHA-384, and SHA-512 as lowercase hex in one pass. SHA algorithms use Web Crypto; MD5 uses a local RFC 1321 implementation.
Does my text leave my device?
No. Hashing runs in your browser. ToolsArk does not upload your text to a hashing API.
Should I use MD5 or SHA-1 for passwords?
No. MD5 and SHA-1 are fine for casual checksums and legacy compatibility, not for storing passwords. Prefer SHA-256 or stronger for integrity checks, and a dedicated password-hashing scheme (such as Argon2 or bcrypt) for credentials — those are outside this tool.
What are the size limits?
Input is limited to about 5 MB of UTF-8 text. Upload accepts .txt files within that limit. This tool hashes text content, not arbitrary binary files as opaque blobs.
Can I copy or download results?
Yes. Copy an individual digest or all digests, or download a labeled text file of the results.
