สร้างภาพ A clean flat infographic showing the encryption concept. On the left side, a document icon with readable text labeled Plain Text. In the middle, a lock icon with a key representing the encryption process. On the right side, a document icon with scrambled unreadable characters labeled Cipher Text. Arrows flow left to right showing the transformation. Below, a reverse arrow shows decryption with another key icon. Modern minimal educational style with soft blue and green colors on white background. (encryption_concept.jpg)

สร้างภาพ A clean flat comparison diagram showing Symmetric vs Asymmetric encryption side by side. Left side labeled Symmetric: two people share the same single key icon, with arrows showing encrypt and decrypt using the same key. Right side labeled Asymmetric: one person has a public key (open lock icon) and private key (closed lock icon), showing how sender encrypts with public key and receiver decrypts with private key. Color coded blue for symmetric and green for asymmetric. Modern minimal educational style on white background. (symmetric_vs_asymmetric.jpg)

สร้างภาพ A clean flat infographic showing the hashing concept. Multiple inputs of different sizes (short text, long document, image file) all passing through a hash function box (depicted as a meat grinder or funnel icon) producing fixed-length output strings of the same size. An important note showing that changing even one character in input produces completely different output. One-way arrow indicating irreversibility. Modern minimal educational style with orange and purple accents on white background. (hashing_concept.jpg)
