About Hash Generator

Generate MD5, SHA-1, SHA-256, and SHA-512 cryptographic hashes from text. Hash Generator runs entirely in your browser — no installation, no uploads, and no data ever leaves your device.

Common use cases: verify file integrity by comparing checksums; hash passwords for storage verification examples; generate content fingerprints for caching. Whether you are debugging, prototyping, or building production code, having a fast and private tool for this task saves time compared to writing one-off scripts or using an online tool that logs your data.

Like every tool in Catalyst, this one is free forever, requires no login, and is safe to use with confidential data. All processing happens client-side via native browser APIs.

Frequently asked questions

Should I use MD5 for password storage?
No. MD5 and SHA-1 are cryptographically broken and should never be used for password storage. Use bcrypt, scrypt, or Argon2 on the server instead. MD5 and SHA-1 are still acceptable for non-security use cases like file checksums and cache keys.
Are hashes computed in my browser?
Yes. All four algorithms run via the Web Crypto API (crypto.subtle.digest) directly in your browser. The input text never leaves your device. MD5, which isn't in Web Crypto, uses a pure-JS implementation locally.
