RIPEMD-160 Hash Calculator
Type or paste text and this calculator returns its RIPEMD-160 hash: a fixed 160-bit digest written as 40 hexadecimal characters. The same input always produces the same digest, which makes it useful for integrity checks, digital signatures, and Bitcoin address derivation. It is maintained by the team at TestMu AI (formerly LambdaTest).

What is RIPE MD 160 Hash Generator?
RIPE MD 160 is a checksum and hash generator for web developers and programmers. Feed it non-sensitive sample input, such as a build number, a file path or a test fixture string, and it returns a one-way digest that cannot be turned back into the original. Whatever you type is sent to our servers to be hashed, so leave real passwords and personal data out of the field. The algorithm generates a 160-bit message digest from an arbitrary quantity of data.
How does the RIPE MD 160 Hash Generator work?
RIPEMD-160 belongs to the RIPEMD group of hash functions. The line opened with the original 128-bit RIPEMD, published in 1992 by the EU's RIPE project; RIPEMD-160 arrived four years later, in 1996, from Hans Dobbertin, Antoon Bosselaers and Bart Preneel at KU Leuven. Its structure borrows from MD4, and although MD4 itself turned out to be weak, the RIPEMD redesign kept the fast 32-bit word operations that suit ordinary processors. Your input is padded, cut into 512-bit blocks and pushed through two parallel compression lines whose results combine into the final 160-bit digest.
What is the RIPEMD-160 Hash Calculator used for?
The cryptographic hashing algorithm called RIPEMD-160 Hash Calculator is based on the Merkle-Damgard architecture. It is used by the Bitcoin standard. It is an enhanced version of the original RIPEMD algorithm, producing a 160-bit hash digest instead of the 128-bit output of the earlier method.
What is the output length of a RIPEMD-160 hash?
The 160-bit (20-byte) hash value generated by RIPEMD160 Hash Calculator is normally represented as a 40-digit hexadecimal number.
Which is faster: RIPEMD-160 or SHA 256?
On a plain software implementation the two land in the same ballpark, and benchmarks such as openssl speed often put RIPEMD-160 marginally ahead of SHA-256. That margin disappears on current hardware: any CPU with SHA-256 acceleration, such as Intel and AMD SHA-NI or the ARMv8 crypto extensions, computes SHA-256 several times faster than RIPEMD-160, which has no equivalent instruction support. Speed is the wrong tie-breaker anyway. A 160-bit digest gives RIPEMD-160 roughly 80-bit collision resistance, while SHA-256's 256-bit digest gives roughly 128-bit, so SHA-256 is the stronger of the two rather than the weaker. No practical collision against the full RIPEMD-160 has been published and it remains in service for Bitcoin address derivation, but SHA-256 is far more widely deployed and is the better default for new work.
