How to use
- Open Hash Generator — Open the hash tool.
- Paste text or use options — Provide the input to hash.
- Choose algorithm — Select MD5 / SHA-1 / SHA-256 as needed.
- Copy digest — Copy the hex digest for checksums or debugging.
Limits
MD5 and SHA-1 are unsuitable for password storage. This is not bcrypt/Argon2.
When to use
Quick integrity checksums and digests without uploading files.
When not to use
Storing user passwords or proving authenticity of signed artifacts.
Privacy note
Digests are computed locally.
FAQ（5）
Are hashes reversible?
No. Cryptographic hashes are one-way; you cannot recover the original from MD5/SHA output.
Is MD5 safe for passwords?
No. Use a password hasher (bcrypt/Argon2/scrypt) server-side. This tool is for checksums and quick digests—not password storage.
Which algorithms are available?
Common options include MD5, SHA-1, and SHA-256 (see the tool UI). Prefer SHA-256 for integrity checks; MD5/SHA-1 only for legacy checksums.
Does hashing upload my file or text?
No. Digests are computed locally in the browser.
Why do hashes change with one character?
Avalanche effect: tiny input changes produce completely different digests.
