Image description
The image is a wide, landscape-oriented infographic that visually explains the Whirlpool hash algorithm at a high, conceptual level without committing to any low-level technical specifics. A clean blue grid background gives the impression of a technical blueprint, while soft light effects add visual depth without distracting from the main flow. At the very top, a bold banner reads "WHIRLPOOL HASH ALGORITHM" in large, white capital letters, establishing the subject clearly.
On the left side of the graphic, a rectangular panel labeled "INPUT DATA" contains simple icons representing generic digital information: stacked documents, a small file card, and an envelope. These icons suggest that any form of data — text, files, or messages — can serve as the input to the hash function. A thick arrow points from this input panel toward the center of the image, guiding the viewer into the main processing area.
The center is dominated by a large circular workflow ring, visually communicating the idea of repeated internal transformations. The ring is divided into several color-coded segments, each with its own label and simple illustrative icon. At the top of the circle, a segment labeled "SUBSTITUTION" shows a small grid of multicolored squares, implying that pieces of data are replaced or transformed. Moving clockwise, the next segment is labeled "PERMUTATION" and features an intertwined ribbon-like graphic, indicating that data elements are rearranged. Another "PERMUTATION" label appears on the left side of the circle, paired with a block-grid icon, reinforcing that rearranging steps happen in multiple places. Below that, a segment labeled "MIXING" is illustrated by a stack of layered, differently colored plates, conveying the idea of combining or blending internal state values.
On the lower right portion of the circle is a segment labeled "ROUND KEY". Its icon shows a small key next to a short binary-style number string, symbolizing that each round introduces additional transformation material. Beneath the circular ring, a ribbon banner reads "REPEATED ROUNDS", emphasizing that the operations in the circle are not executed once, but many times in succession. Directly below this banner, a rectangular box labeled "FINAL COMPRESSION" suggests a concluding stage where the internally transformed state is condensed into the final result.
From the right side of the circle, a bold arrow leads to a panel labeled "HASH OUTPUT". Inside this panel is a stylized hexadecimal-looking string ending with ellipses, visually representing a fixed-length digest without specifying any real parameters. A curved arrow loops back from the output area toward the bottom of the diagram, visually tying the final compression and output together and reinforcing the idea of a well-defined, closed process.
Overall, the image uses clear arrows, simple icons, and high-contrast colors to make the high-level structure of the Whirlpool hashing process easy to grasp, while deliberately avoiding any exact implementation details that could become outdated or misleading.
