# pyhexdmp Python hex dump module #### Copyright 2021 #### Author: Paul Melson ## Author notes: * Accept single variable as input, plus optional config arguments * Detect data type of input * Supported data types: str, bytes, bytearray * Unsupported data types: complex, bool, int, float * Undecided (currently unsupported): list, dict, range, tuple, memoryview * Convert input to bytearray() * Print hex output format, supported optional arguments: * **offsets**: on/off, default=on, print the distance of the first byte of each line in hex notation on the left ```python hexdmp(test_data, offsets='off') ``` * **showascii**: on/off, default=on, print the ASCII characters of each byte on the right (print periods for hi/lo bytes) ```python hexdmp(test_data, showascii='off') ``` * **start**: int, manually set offsets start value ```python hexdmp(test_data, start=2) ``` * **width**: positive int, default=16, let the user set the number of bytes per line to print ```python hexdmp(test_data, width=8) ``` ## Usage: ``` >>> from pyhexdmp import hexdmp >>> with open('/home/paul/sample.exe', 'rb') as f: ... raw = f.read() ... >>> test_data = raw[:128] >>> hexdmp(test_data) 00000000: 4d 5a 90 00 03 00 00 00 04 00 00 00 ff ff 00 00 MZ.............. 00000010: b8 00 00 00 00 00 00 00 40 00 00 00 00 00 00 00 ........@....... 00000020: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00000030: 00 00 00 00 00 00 00 00 00 00 00 00 f8 00 00 00 ................ 00000040: 0e 1f ba 0e 00 b4 09 cd 21 b8 01 4c cd 21 54 68 ........!..L.!Th 00000050: 69 73 20 70 72 6f 67 72 61 6d 20 63 61 6e 6e 6f is program canno 00000060: 74 20 62 65 20 72 75 6e 20 69 6e 20 44 4f 53 20 t be run in DOS 00000070: 6d 6f 64 65 2e 0d 0d 0a 24 00 00 00 00 00 00 00 mode....$....... >>> hexdmp(test_data, offsets='off') 4d 5a 90 00 03 00 00 00 04 00 00 00 ff ff 00 00 MZ.............. b8 00 00 00 00 00 00 00 40 00 00 00 00 00 00 00 ........@....... 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 00 00 00 00 f8 00 00 00 ................ 0e 1f ba 0e 00 b4 09 cd 21 b8 01 4c cd 21 54 68 ........!..L.!Th 69 73 20 70 72 6f 67 72 61 6d 20 63 61 6e 6e 6f is program canno 74 20 62 65 20 72 75 6e 20 69 6e 20 44 4f 53 20 t be run in DOS 6d 6f 64 65 2e 0d 0d 0a 24 00 00 00 00 00 00 00 mode....$....... >>> hexdmp(test_data, showascii='off') 00000000: 4d 5a 90 00 03 00 00 00 04 00 00 00 ff ff 00 00 00000010: b8 00 00 00 00 00 00 00 40 00 00 00 00 00 00 00 00000020: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00000030: 00 00 00 00 00 00 00 00 00 00 00 00 f8 00 00 00 00000040: 0e 1f ba 0e 00 b4 09 cd 21 b8 01 4c cd 21 54 68 00000050: 69 73 20 70 72 6f 67 72 61 6d 20 63 61 6e 6e 6f 00000060: 74 20 62 65 20 72 75 6e 20 69 6e 20 44 4f 53 20 00000070: 6d 6f 64 65 2e 0d 0d 0a 24 00 00 00 00 00 00 00 >>> hexdmp(test_data, start=2) 00000002: 90 00 03 00 00 00 04 00 00 00 ff ff 00 00 b8 00 ................ 00000012: 00 00 00 00 00 00 40 00 00 00 00 00 00 00 00 00 ......@......... 00000022: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00000032: 00 00 00 00 00 00 00 00 00 00 f8 00 00 00 0e 1f ................ 00000042: ba 0e 00 b4 09 cd 21 b8 01 4c cd 21 54 68 69 73 ......!..L.!This 00000052: 20 70 72 6f 67 72 61 6d 20 63 61 6e 6e 6f 74 20 program cannot 00000062: 62 65 20 72 75 6e 20 69 6e 20 44 4f 53 20 6d 6f be run in DOS mo 00000072: 64 65 2e 0d 0d 0a 24 00 00 00 00 00 00 00 de....$....... >>> hexdmp(test_data, width=8) 00000000: 4d 5a 90 00 03 00 00 00 MZ...... 00000008: 04 00 00 00 ff ff 00 00 ........ 00000010: b8 00 00 00 00 00 00 00 ........ 00000018: 40 00 00 00 00 00 00 00 @....... 00000020: 00 00 00 00 00 00 00 00 ........ 00000028: 00 00 00 00 00 00 00 00 ........ 00000030: 00 00 00 00 00 00 00 00 ........ 00000038: 00 00 00 00 f8 00 00 00 ........ 00000040: 0e 1f ba 0e 00 b4 09 cd ........ 00000048: 21 b8 01 4c cd 21 54 68 !..L.!Th 00000050: 69 73 20 70 72 6f 67 72 is progr 00000058: 61 6d 20 63 61 6e 6e 6f am canno 00000060: 74 20 62 65 20 72 75 6e t be run 00000068: 20 69 6e 20 44 4f 53 20 in DOS 00000070: 6d 6f 64 65 2e 0d 0d 0a mode.... 00000078: 24 00 00 00 00 00 00 00 $....... >>> hexdmp(test_data, offsets='off', showascii='off', start=16, width=32) b8 00 00 00 00 00 00 00 40 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 f8 00 00 00 0e 1f ba 0e 00 b4 09 cd 21 b8 01 4c cd 21 54 68 69 73 20 70 72 6f 67 72 61 6d 20 63 61 6e 6e 6f 74 20 62 65 20 72 75 6e 20 69 6e 20 44 4f 53 20 6d 6f 64 65 2e 0d 0d 0a 24 00 00 00 00 00 00 00p >>> from pyhexdmp import strhexdmp >>> test_hexdump_string = strhexdmp(test_data) >>> print(test_hexdump_string) 00000000: 4d 5a 90 00 03 00 00 00 04 00 00 00 ff ff 00 00 MZ.............. 00000010: b8 00 00 00 00 00 00 00 40 00 00 00 00 00 00 00 ........@....... 00000020: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00000030: 00 00 00 00 00 00 00 00 00 00 00 00 f8 00 00 00 ................ 00000040: 0e 1f ba 0e 00 b4 09 cd 21 b8 01 4c cd 21 54 68 ........!..L.!Th 00000050: 69 73 20 70 72 6f 67 72 61 6d 20 63 61 6e 6e 6f is program canno 00000060: 74 20 62 65 20 72 75 6e 20 69 6e 20 44 4f 53 20 t be run in DOS 00000070: 6d 6f 64 65 2e 0d 0d 0a 24 00 00 00 00 00 00 00 mode....$....... >>> ```
