Convert from ASCII string encoded in Hex to plain ASCII?
PythonHexAsciiPython Problem Overview
How can I convert from hex to plain ASCII in Python?
Note that, for example, I want to convert "0x7061756c" to "paul".
Python Solutions
Solution 1 - Python
A slightly simpler solution:
>>> "7061756c".decode("hex")
'paul'
Solution 2 - Python
No need to import any library:
>>> bytearray.fromhex("7061756c").decode()
'paul'
Solution 3 - Python
>>> txt = '7061756c'
>>> ''.join([chr(int(''.join(c), 16)) for c in zip(txt[0::2],txt[1::2])])
'paul'
i'm just having fun, but the important parts are:
>>> int('0a',16) # parse hex
10
>>> ''.join(['a', 'b']) # join characters
'ab'
>>> 'abcd'[0::2] # alternates
'ac'
>>> zip('abc', '123') # pair up
[('a', '1'), ('b', '2'), ('c', '3')]
>>> chr(32) # ascii to character
' '
will look at binascii now...
>>> print binascii.unhexlify('7061756c')
paul
cool (and i have no idea why other people want to make you jump through hoops before they'll help).
Solution 4 - Python
In Python 2:
>>> "7061756c".decode("hex")
'paul'
In Python 3:
>>> bytes.fromhex('7061756c').decode('utf-8')
'paul'
Solution 5 - Python
b''.fromhex('7061756c')
use it without delimiter
Solution 6 - Python
Here's my solution when working with hex integers and not hex strings:
def convert_hex_to_ascii(h):
chars_in_reverse = []
while h != 0x0:
chars_in_reverse.append(chr(h & 0xFF))
h = h >> 8
chars_in_reverse.reverse()
return ''.join(chars_in_reverse)
print convert_hex_to_ascii(0x7061756c)
Solution 7 - Python
Tested in Python 3.3.2 There are many ways to accomplish this, here's one of the shortest, using only python-provided stuff:
import base64
hex_data ='57696C6C20796F7520636F6E76657274207468697320484558205468696E6720696E746F20415343494920666F72206D653F2E202E202E202E506C656565656173652E2E2E212121'
ascii_string = str(base64.b16decode(hex_data))[2:-1]
print (ascii_string)
Of course, if you don't want to import anything, you can always write your own code. Something very basic like this:
ascii_string = ''
x = 0
y = 2
l = len(hex_data)
while y <= l:
ascii_string += chr(int(hex_data[x:y], 16))
x += 2
y += 2
print (ascii_string)

>>> print "\x70 \x61 \x75 \x6c"
p a u l
>>> exit()

Solution 9 - Python
No need to import anything, Try this simple code with example how to convert any hex into string
python hexit.py
Hex it>>some string
736f6d6520737472696e67
python tohex.py
Input Hex>>736f6d6520737472696e67
some string
cat tohex.py
s=input("Input Hex>>")
b=bytes.fromhex(s)
print(b.decode())
