In computing, a hex dump is a textual hexadecimal view (on screen or paper) of (often, but not necessarily binary) computer data, from memory or from a computer file or storage device. Looking at a hex dump of data is usually done in the context of either debugging , reverse engineering or digital forensics . [ 1 ]
256 byte hex dump of /dev/urandom In Unix-like operating systems , /dev/random and /dev/urandom are special files that serve as cryptographically secure pseudorandom number generators (CSPRNGs). They allow access to a CSPRNG that is seeded with entropy (a value that provides randomness ) from environmental noise, collected from device drivers ...
The od program can display output in a variety of formats, including octal, hexadecimal, decimal, and ASCII.It is useful for visualizing data that is not in a human-readable format, like the executable code of a program, or where the primary form is ambiguous (e.g. some Latin, Greek and Cyrillic characters looking similar).
The line-oriented debugger DEBUG.EXE is an external command in operating systems such as DOS, OS/2 and Windows (only in 16-bit/32-bit versions [1])..
