Overview
Hexadecimal is a base-16 representation that uses 0-9 and a-f to express values. In analysis work, two hex characters commonly represent one byte, which makes hex a compact way to display raw binary data without losing byte-level precision.
Hex appears in hashes, packet captures, file signatures, memory dumps, encoded strings, and debugging output. Being able to move between hex, bytes, and text is a core analysis skill.
In this lab, you practice converting hexadecimal byte values into meaningful data, grouping bytes correctly, and separating encoded data from cryptographic protection.
