Which hash algorithms are supported?

MD5, SHA-1, SHA-256, SHA-384, and SHA-512 via the Web Crypto API, plus HMAC with a secret key. SHA-256 is recommended for most uses.

Is my input sent to a server?

No. Hashing runs locally using the browser's native crypto, so your input never leaves your device.

Should I use MD5 or SHA-1 for security?

No. MD5 and SHA-1 are broken for security purposes. Use SHA-256 or stronger for anything security-sensitive; older algorithms are only for non-security checksums.

Can I hash passwords with this tool?

Not for storage. Password storage needs a slow, salted key-derivation function like bcrypt or Argon2 — not a plain hash. This tool is for checksums and fingerprints.

Is the output always the same for the same input?

Yes. The same input and algorithm always produce the same digest, which is exactly what makes hashes useful for verification.

About this tool

The Hash Generator computes cryptographic hashes — including SHA-256, SHA-1, SHA-384, SHA-512, and MD5 — from any text, right in your browser. Paste input and get the hex or Base64 digest instantly using the native Web Crypto API, with nothing sent to a server. It also supports HMAC and constant-time hash comparison, making it handy for checksums, fingerprinting, and verifying data integrity.

How to use it

Enter your text. Paste or type the text you want to hash.
Pick an algorithm. Choose SHA-256, SHA-1, SHA-384, SHA-512, or MD5 — or generate all at once.
Read the digest. The hash is computed instantly and shown as hex or Base64.
Copy the hash. Copy the digest to your clipboard for checksums or comparisons.
