Hash Generator is a free online tool that computes MD5, SHA-1, and SHA-256 hashes of your text directly in your browser, producing a fixed-length fingerprint used to verify data integrity.
What a hash is
A hash is a fixed-length fingerprint of any input, produced by a one-way function. The same input always yields the same hash, but you cannot reverse a hash back into the original data. Hashes are used to verify that a file or message has not changed, to index data, and as a building block in many security systems.
The common algorithms
MD5 produces a 128-bit hash shown as 32 hexadecimal characters and is fast but no longer considered safe against deliberate collisions. SHA-1 produces a 160-bit, 40-character hash and is also deprecated for security use. SHA-256, part of the SHA-2 family, produces a 256-bit, 64-character hash and is the current standard for integrity and security work.
Verifying integrity
Hashes are the standard way to confirm a download or message arrived intact. A publisher lists the expected hash, you compute the hash of your copy, and if they match the data is identical. Even a one-character change produces a completely different hash, which is why hashing reliably catches corruption and tampering.
Private and local
Hash Generator runs entirely in your browser using the Web Crypto API for SHA algorithms. Your text is hashed locally and is never uploaded or stored, so sensitive input stays on your device. The computation is instant and no server sees your data.
사용 방법 해시 생성기
- Open the Hash Generator tool.
- Type or paste your text into the box.
- Choose an algorithm such as MD5, SHA-1, or SHA-256.
- See the hash computed instantly in your browser.
- Copy the resulting hash.
Verify a download
Verify a download
Compute the SHA-256 of a file's text and compare it with the publisher's listed hash to confirm integrity.
Fingerprint a string
Generate a stable hash of a value to use as a consistent identifier or cache key.
Check for changes
Hash a message before and after transit to confirm it was not altered along the way.
| Algorithm | Output length | Status |
|---|---|---|
| MD5 | 32 hex characters | Legacy, not secure |
| SHA-1 | 40 hex characters | Deprecated |
| SHA-256 | 64 hex characters | Current standard |
