Image description
The image presents a clean, educational visualization of the RIPEMD-128 hash algorithm, designed to convey the overall idea without relying on potentially inaccurate implementation specifics. It is rendered in landscape orientation with a wide horizontal flow, guiding the viewer from left to right. At the far left, a large box labeled "Input Message" represents any arbitrary-length data such as text or files. Beneath it, a small caption notes that the message can be of any size, emphasizing that hash functions accept variable-length input.
From the input box, an arrow leads into a stage titled "Preparation", which visually suggests that the message is transformed into a form suitable for processing. This stage is intentionally abstract, using icons of split segments and padding shapes rather than numerical values. The next area, labeled "Message Blocks", shows the prepared message divided into equal-sized blocks arranged in a row, indicating that the algorithm works on chunks of data rather than the entire message at once.
The center of the diagram is dominated by a large container titled "RIPEMD-128 Core Processing". Inside this container, the path splits into two parallel lanes marked "Left Path" and "Right Path". Each lane is drawn as a vertical stack of rounded rectangles labeled generically as "Mixing Step", "Non-linear Operation", and "State Update". These labels are repeated several times to imply multiple rounds, but without stating the exact number or formulas. Curved arrows show that both paths process the same block in parallel, visually reinforcing the idea of dual processing streams.
At the bottom of each path, arrows converge into a "Combine Results" box. This convergence symbolizes the merging of the two parallel results into a single internal state. Another arrow then loops back upward to the message block row, illustrating that the process repeats for every block until the entire message has been consumed.
On the far right of the image, the final arrow exits the processing container and points to a prominent box labeled "128-bit Hash Output". This box is styled with a binary motif and a lock icon, reinforcing the notion of a compact, fixed-size digest used for integrity or identification. A small note under the box explains that the output is always the same size regardless of input length.
The overall color scheme uses soft blues and greens for data flow, with contrasting orange accents for the parallel paths to make them easy to distinguish. Simple icons, minimal text, and ample spacing make the visualization approachable to beginners, while the absence of hardcoded constants or equations ensures the diagram remains accurate at a conceptual level.
