Convert 16 bytes of random data to integer in Python


Convert 16 bytes of random data to integer in Python

seems to work fine I have generated a random 16 byte string. It looks like this: , In Python 3.2+, you can use int.from_bytes():
code :
>>> int.from_bytes(b'\xb68 \xe9L\xbd\x97\xe0\xd6Q\x91c\t\xc3z\\', byteorder='little')
122926391642694380673571917327050487990
>>> int.from_bytes(b'\xb68 \xe9L\xbd\x97\xe0\xd6Q\x91c\t\xc3z\\', byteorder='big')

seems to work fine Sven has you answer. However, byte shifting numbers (as in your question) is also possible in Python:
code :
>>> [hex(0x12345678 >> i & 0xff) for i in (24,16,8,0)]
['0x12', '0x34', '0x56', '0x78']

I wish this helpful for you return_data[5:6] returns an array consisting of a single element at index 5:
code :
>>> return_data = b'\00\01\02\03\04\05\06'
>>> return_data[5:6]
b'\x05'

I hope this helps you . In binary, 3 and 132 are 00000011 and 10000100 respectively. 900 in binary is 1110000100. By concatenating the binary representations of 3 and 132, you get 900.
code :
00000011
+       10000100
================
0000001110000100
>>> import struct
>>> x = b'\x00\x00\x03\x84\x00\x00\x04\xb0'
>>> struct.unpack(">II", x)
(900, 1200)

hop of those help? Once you find the unsigned result using the above method, you can convert it to a signed integer:
code :
max_int = 2**(8*len(data)-1)-1
result = result - (2 * (max_int + 1) if result > max_int else 0)

around this issue You can use the struct module to convert between integers and representation as bytes. In your case, to convert from a Python integer to two bytes and back, you'd use:
