RIPEMD-160 hash generator.

Paste text or drop a file and read its RIPEMD-160 digest as you type. RIPEMD-160 is the European 160-bit hash from 1996, unbroken but short, kept alive by Bitcoin addresses; everything runs in your browser and nothing is uploaded.160 bits40 hex characters1996 published0 bytes uploaded

How it works

4 steps, no account. It runs in your browser and nothing is uploaded.

  1. Enter text or a file

    Type or paste anything, or drop a file onto the input. The digest updates with every keystroke.

  2. Pick the algorithm and format

    RIPEMD-160 is the default; switch to MD4, MD5 and SHA-1, and read the digest as hex or Base64.

  3. Key it, when you need a signature

    Turn on HMAC and enter a secret to sign the input instead of hashing it.

  4. Verify, copy or download

    Paste a published digest to confirm a download, or copy and download your own.

The older hashes against today's

The 1990s hashes are checksums now. Each was state of the art once; each has a published collision. Use them to catch corruption, never to stop an attacker.

  • MD4

    128 bits, 1990. Collisions by hand since 2004, in microseconds by computer. Survives only inside NTLM and old ed2k links.

  • MD5

    128 bits, 1992. Collisions in seconds, chosen-prefix collisions since 2007. A checksum for accidental damage, nothing more.

  • SHA-1

    160 bits, 1995. A real collision in 2017, a chosen-prefix one in 2020. Git is moving off it; certificates already have.

  • RIPEMD-160

    160 bits, 1996. No attack on the full function, but 160 bits is below today's margin. Lives on in Bitcoin addresses.

  • SHA-256

    256 bits, 2001. No known attack, hardware-accelerated. The default replacement for every one of the above.

  • SHA3-256

    256 bits, 2015. A sponge, not a Merkle–Damgård chain: a different design in case SHA-2 ever falls.

  • BLAKE3

    256 bits, 2020. Faster than MD5 on a modern CPU and still secure: the honest answer to "but MD5 is fast".

  • CRC32

    32 bits, 1961. Not a hash at all but a checksum: when you only need to catch a flipped bit, this is the right tool.
