Hash Generator – Create MD5, SHA-1, SHA-256 and SHA-512 Digests
The hash generator calculates cryptographic digests (hashes) of text or files using different algorithms: MD5, SHA-1, SHA-256, and SHA-512. Works in browser without server connection — data doesn't go anywhere.
Enter text or upload a file, and you'll see the digest immediately with all algorithms. Used for file integrity verification, password storage, and digital signatures.
What's the Difference Between MD5, SHA-1, and SHA-256?
MD5 produces a 128-bit digest — fast but vulnerable to collision attacks, no longer secure for passwords. SHA-1 (160 bits) is also outdated from a security perspective. SHA-256 (256 bits) is the current standard and sufficiently secure for most use cases. SHA-512 is even stronger but slower.

Enter text or file, and the tool calculates a digest using your chosen algorithm.
- Supports common algorithms: MD5, SHA-1, SHA-256, and SHA-512.
- Copy hash value to clipboard with one click.
- Compare two inputs' digests to verify file integrity.
Hash is a one-way digest – original content cannot be recovered from hash.
- If two inputs produce the same hash, content is practically identical.
- MD5 and SHA-1 are no longer secure for password protection.
- SHA-256 is a good choice for general use in current standards.
Digests are not encryption – they're suitable for integrity checking, not data protection.
- Don't use plain hash for password storage – use bcrypt or similar.
- Calculation happens entirely in browser, your data isn't sent to servers.
- Processing very large files may be slow in browser.
