Security note: hashes are one-way cryptographic fingerprints — they cannot normally be reversed back into the original data. Nothing you enter into this tool ever leaves your browser.

How It Works

1

Enter text or upload a file

Type or paste text, or select a local file to hash.

2

Choose algorithms

Select any combination of MD5, SHA-1, SHA-256, SHA-384 and SHA-512.

3

Copy or download the generated hashes

Copy any single hash, copy all of them, or download a full report.

Common Uses

Password verification Compare stored hashes against submitted credentials.
File integrity Confirm a downloaded file matches its published hash.
Software verification Verify installers and releases haven't been tampered with.
Checksums Detect accidental corruption during transfer or storage.
Digital forensics Fingerprint evidence files to prove they weren't altered.
Development Generate cache keys, ETags and content fingerprints.
Cybersecurity Match hashes against known-malware or breach databases.
APIs Sign requests and verify webhook payload integrity.
Database records De-duplicate rows or index large text fields efficiently.
Version tracking Identify exactly which build or asset version is deployed.

Frequently Asked Questions

What is a hash?+

A hash is a fixed-length fingerprint produced by running data through a cryptographic algorithm. The same input always produces the same hash, and even a tiny change in the input produces a completely different one.

Can hashes be reversed?+

No. Hashing is a one-way function. You cannot recover the original data from a hash, which is why hashes are used to verify data rather than store it directly.

What is the difference between hashing and encryption?+

Encryption is reversible with the right key, so the original data can be recovered. Hashing is one-way and produces a fixed-size fingerprint that cannot be decrypted back into the source data.

Which algorithm should I use?+

For security-sensitive work use SHA-256 or higher. MD5 and SHA-1 are fine for quick checksums or file-integrity checks where collision resistance doesn't matter.

Why is MD5 considered insecure?+

MD5 is vulnerable to collision attacks, meaning two different inputs can be crafted to produce the same hash. It should not be used for passwords, signatures or anything security-critical.

Is SHA-256 secure?+

Yes. SHA-256 has no known practical collision or preimage attacks and is widely used in TLS certificates, blockchains and modern security systems.

Can I hash files with this tool?+

Yes. Switch to File mode, choose a local file, and the tool computes its hash directly in your browser without uploading it anywhere.

Does this tool upload my data?+

No. All hashing happens locally using your browser's built-in cryptographic functions. Nothing you type or upload ever leaves your device.
