Hash All Generator
Compute every common digest of any text at once — CRC-32, MD5, SHA-1, the SHA-2 family, SHA-3, RIPEMD-160, BLAKE2, BLAKE3 and Whirlpool — in one labeled table. Runs entirely in your browser, no server, no sign-up.
About this tool
This hash-all generator computes every common digest of the same text at once and lays them out in one labeled table, right in your browser. The hashing runs locally in WebAssembly — your input is never uploaded to a server, which makes it safe for passwords, keys, and other sensitive strings.
A hash is a fixed-length fingerprint of its input. The same text always produces the same digest, but the digest cannot be reversed back into the original — so hashes are ideal for verifying that data has not changed, fingerprinting content, and deriving identifiers. Computing all of them at once is handy when you do not yet know which algorithm a system expects, or when you want to compare a value against several candidates side by side.
Algorithms computed
- CRC-32 — a fast non-cryptographic checksum (the IEEE variant used by zip, gzip, and PNG). For error-detection only, never security.
- MD5 and SHA-1 — widely supported but broken for security use; treat them as checksums only, not for passwords or signatures.
- SHA-2 family — SHA-224, SHA-256, SHA-384, SHA-512. SHA-256 is the standard modern choice: it secures TLS certificates, Git object IDs, and download checksums.
- SHA-3 family — SHA3-256 and SHA3-512, the Keccak-based NIST standard with a different internal design from SHA-2.
- RIPEMD-160 — a 160-bit hash used in Bitcoin and PGP key fingerprints.
- BLAKE2 (BLAKE2b-512, BLAKE2s-256) and BLAKE3 — modern hashes that are typically faster than SHA-2 while remaining cryptographically strong.
- Whirlpool — a 512-bit hash from the ISO/IEC 10118-3 standard.
Options
- Interpret input as — hash the text as plain UTF-8 (default), or decode it from hex or base64 first so you can hash existing raw bytes such as a key or ciphertext.
- Output format — render every digest as hex (default) or as base64.
- Uppercase hex — emit the hex digests in uppercase.
Notes
- A hash is a one-way function: a digest cannot be reversed back into the original text.
- To compute a single chosen algorithm use the hash-text tool; to hash an entire file use the file-hash tool instead.
FAQ
Can I hash raw bytes (a key, ciphertext) instead of plain text?
Yes — set Interpret input as to hex or base64 and the tool decodes your input to raw bytes before hashing. Invalid hex or base64 is rejected with a clear error rather than silently hashed as text. The default (utf8) hashes the characters exactly as you typed them.
Why does my SHA-256 differ from what another tool prints?
The bytes being hashed differ. The usual culprits: a trailing newline or space (this tool hashes your input exactly, with no trimming), a different input interpretation (utf8 vs hex/base64), or comparing a base64-rendered digest against a hex one. Digest case never matters for hex — use the Uppercase hex toggle if you need to match a shouting-case reference.
Which of these algorithms are still safe for security purposes?
SHA-2 (SHA-256/384/512), SHA-3, BLAKE2, and BLAKE3 are all considered cryptographically strong. MD5 and SHA-1 are broken — collisions are practical — so treat them as integrity checksums for legacy systems only, and CRC-32 is purely an error-detection code, never a security primitive.
Does it work on files too?
This page hashes text (or hex/base64-encoded bytes) you paste in. For hashing a whole file, use the dedicated file-hash tool; for computing just one chosen algorithm, the hash-text tool is quicker.
