加密原理流程图

一张深色模式流程图信息图，在深炭灰（#1A1A2E）背景上展示对称与非对称加密原理。两条平行轨道垂直排列：左轨为青色节点的 「加密原理流程图」；右轨为琥珀色节点的 RSA 流程。中央菱形决策节点：「Same key?」 分叉至两轨。节点为带 1px 亮边框的圆角矩形，内部使用等宽字体标签。顶部电紫色标注横幅写道："Every HTTPS handshake uses both methods simultaneously."底部右侧图例，顶部白色粗体压缩标题。

A dark-mode flowchart infographic illustrating symmetric and asymmetric encryption on a deep charcoal (#1A1A2E) background. Two parallel tracks run vertically: left track shows "Plaintext → AES Encrypt → Ciphertext → AES Decrypt → Plaintext" with teal nodes; right track shows "Plaintext → RSA Public Key → Ciphertext → RSA Private Key → Plaintext" with amber nodes. Diamond decision node in the center: "Same key?" branches to each track. All nodes are rounded rectangles with 1px bright borders. Monospace labels inside each node. Callout ribbon across the top in electric purple reads: "Every HTTPS handshake uses both methods simultaneously." Thin connecting lines with animated-style dashes. Legend at bottom-right. Bold condensed title at top in white.
