Checksum Generator
Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 checksums from the same input in one click. Useful for matching downloaded files against publisher checksums, building manifests, and migrating between hash standards.
One input, five fingerprints
Each algorithm produces a fixed-size hex string — 32 chars for MD5, up to 128 for SHA-512.
Hello, world!
MD5 6cd3556deb0da54bca060b4c39479839 SHA-1 943a702d06f34599aee1f8da8ef9f7296031d699 SHA-256 315f5bdb76d078c43b8ac0064e4a0164612b1fce77c869345bfc94c75894edd3
Where multi-hash helps
Different ecosystems pin to different algorithms. Generate all five at once and pick the one you need.
Security audits
Match downloaded binaries against the publisher's checksum file (often multiple algorithms listed).
API auth
Some APIs sign with one algorithm; some with another. Generate both for testing.
File integrity
Build manifests with multiple hashes so the right one is available when needed.
Tokens & IDs
Generate deterministic IDs and pick the algorithm that fits your storage size.
How to generate multiple checksums

Frequently asked questions
MD5, SHA-1, SHA-256, SHA-384, and SHA-512. Each is the hex-encoded digest of the same input bytes.
No. Plain hashes (even SHA-512) are unsuitable for password storage. Use bcrypt, scrypt, or Argon2.
Yes — for the same UTF-8 byte sequence, the hex output matches md5sum, sha256sum, etc. Watch for trailing newlines.
For non-security uses (cache keys, dedupe, ETags) MD5 is fast and short. Just don't use it where an attacker could craft input.
Yes. No signup, no limits, no ads. Everything runs in your browser.
About cryptographic checksums
A checksum is a fixed-size fingerprint of arbitrary input. Cryptographic hash functions go further: they make it computationally infeasible to find two inputs with the same digest, or to reverse a digest into its input.
Algorithms compared
- MD5 — 128-bit, fast, broken. Use only for non-security checksums.
- SHA-1 — 160-bit, also broken (SHAttered, 2017). Legacy systems only.
- SHA-256 — 256-bit, modern default for TLS, Bitcoin, JWT.
- SHA-384 / SHA-512 — longer digests; SHA-512 is faster on 64-bit CPUs.
Tips
- Whitespace and line endings change the hash — strip them or include them deliberately.
- For passwords, never use a plain hash. Use bcrypt, scrypt, or Argon2.
- For authenticated hashes (with a secret key) use HMAC.
