RIPEMD128 generator

What Is RIPEMD-128?

RIPEMD-128 is the 128-bit variant of the RIPEMD family, developed in the 1990s European RIPE project as an open alternative to NSA-designed hashes. It produces a 32-hex-character digest from two parallel computation lines.

Security Status

Collision attacks against RIPEMD-128 have been demonstrated by researchers — it should be considered broken for collision resistance, like MD5. It survives here for legacy checksum matching and cryptographic archaeology, not for new security designs.

What to Use Instead

For new work: SHA-256 (or RIPEMD-160 if you specifically need the RIPEMD lineage, as Bitcoin does). Never deploy RIPEMD-128 where an attacker benefits from crafting collisions.

How to Use the RIPEMD-128 Hash Generator

RIPEMD-128 is the 128-bit member of the European RIPEMD family (1996) — a contemporary of MD5 with a parallel-line design, useful for legacy compatibility and hash research.

1. Enter the message to digest with RIPEMD-128 — the 128-bit hash developed in the European RIPE project.
2. Click the hash button to compute the 128-bit RIPEMD digest.
3. Copy the 32-character hexadecimal result for compatibility checks or comparative hash studies.

Example

Hashing the word hello with RIPEMD-128 always produces the same 32-character hexadecimal result — try it and compare the value against other 128-bit hashes like MD5 to see how different designs digest the same input.

Frequently Asked Questions

What does RIPEMD stand for?
RIPE Message Digest — it was developed within the European RIPE project as an open alternative to the American MD-family hashes of the early 1990s.

Is RIPEMD-128 secure?
No — 128-bit digests no longer offer an adequate security margin, and the original RIPEMD-128 is considered weak. It survives for compatibility and study, not for new security designs.

How is it different from MD5?
RIPEMD-128 processes data through two parallel computation lines instead of MD5 single line, giving it a distinct structure despite the same digest size.
