Image description
The infographic is a wide, landscape-oriented technical visualization of the HAVAL-256/3 cryptographic hash algorithm, designed in a futuristic blue-and-orange cyber style. On the far left, a column labeled "INPUT DATA" shows binary digits cascading into a funnel marked "PADDING & LENGTH APPENDING", representing the preprocessing stage where the original message is padded and its bit length is appended. Beneath the funnel, a glowing panel clearly states "1024-BIT BLOCKS", indicating that the padded message is divided into fixed-size 1024-bit blocks. These blocks flow downward into a "MESSAGE BLOCKS" section, with individual blocks labeled B1 and B2, from which arrows lead into the main compression pipeline.
The central area is enclosed in a large rounded rectangle titled "3 PASSES", emphasizing that HAVAL-256/3 performs three sequential passes over each block. Inside this region are three horizontal stages labeled PASS 1, PASS 2, and PASS 3, each with small schematic circuits illustrating the internal mixing operations. To the right of these stages is a vertical stack of small register boxes labeled with letters such as B, C, D, E, and F, symbolizing the algorithm’s internal state words that are updated during processing. A label reading "96 ROUNDS" appears near the right edge of the passes area, summarizing that the three passes together consist of 96 total steps.
Below the passes, a framed section labeled "HAVAL FUNCTION" breaks down the core per-round operations. Within it, the function f(x, y, z) is shown feeding into a sequence of operators including addition, rotation, and multiplication-style symbols, all connected by arrows to illustrate the nonlinear transformations applied to the state. This block visually conveys how message words and internal registers are combined and permuted during each round.
On the far right, multiple glowing lines converge toward a large golden padlock icon embedded in a stylized circuit board background, representing the security outcome of the hashing process. Beneath the padlock, a prominent box reads "256-BIT HASH VALUE", followed by a truncated hexadecimal digest string beginning with "D95A5B59A335933988A06A96..." to illustrate the final output format. Along the bottom of the infographic, the title "HAVAL-256/3 HASH ALGORITHM" is displayed in bold lettering. Overall, the diagram presents the full data flow from raw input through padding, 1024-bit block processing, three-pass compression with 96 rounds, and finally to the fixed-length 256-bit hash result, using color-coded arrows and panels to make the structure and stages of the algorithm easy to follow.
