How to convert a OID into name in Python

Hi @aikimark,

Thanks for your response, I am wondering what is the \xle before the actual vserver's name

also based upon your example I tried to do it with below OID:

31.73.78.97.121.105.103.108.121.98.121.118.98.53.111.52.100.108.103.114.109.97.114.100.115.104.120.97.100.120.100.48

Select allOpen in new window

and I didn't get expected response

>>> a = '31.73.78.97.121.105.103.108.121.98.121.118.98.53.111.52.100.108.103.114.109.97.114.100.115.104.120.97.100.120.100.48'
>>> ''.join([chr(int(x)) for x in a.split('.')])
'\x1fINayiglybyvb5o4dlgrmardshxadxd0'

Select allOpen in new window

I was expecting vs:single:test-machine-vip-tier1:http@80

appreciate your suggestion here

the period-delimited numbers are ASCII character values.  Since there is no equivalent character to represent the value of 30 or 31, Pyton converts those characters when it  displays or prints them.  I don't know why your second test string produced such weird results.

Thanks @aikimark for such quick response.

I appreciate any suggestion on where to look for ( any python module or function ) to convert \x1fINayiglybyvb5o4dlgrmardshxadxd0 to vs:single:test-machine-vip-tier1:http@80

any suggestion on what kind of encoding or conversion it could be? Thanks in advance

one unique things I see here is that if length of character of a vserver name is equal or more than 32 then only it gives weird result

after a little research, the first number is the length of the remaining character string

This is what I find after a little research in reverse engineering

vs:single:test-machine-vip-tier1:http@80

Select allOpen in new window

will convert to md5 hash

0023b370 b886effc cb4406e2 f25c30ee

Select allOpen in new window

and it's will converted to (Transform a 8 digits hex string (32 bits) a into a 32 bit unsigned long, little-endian)

1890788096 4243556024 3792061643 3996146930 

Select allOpen in new window

and using below script it will be converted as per ascii table

response = ''
ascii_map = 'abcdefghijklmnopqrstuvwxyz012345'
for j in range(7):
    response += ascii_map[(int('3996146930') >> (5*j)) & 31]
print response

Select allOpen in new window

Then Append IN if vserver's name is >=32 and and append last character of vserver's name , which is 0

INayiglybyvb5o4dlgrmardshxadxd0

Select allOpen in new window

and then it will be converted to as per ascii table

31.73.78.97.121.105.103.108.121.98.121.118.98.53.111.52.100.108.103.114.109.97.114.100.115.104.120.97.100.120.100.48

Select allOpen in new window

also as you mentioned it appends 31 as count of remaining chracter which makes it a total size of 32

since there is hashing algorithm (md5) involved, making it difficult ( impossible? ) to change from OID to actual name

Correct.  You have posted two OID strings.  The first one was simple to decode and gave you almost expected results.  Is the second string from a different source, since it goes through a hash process?

That bit of Python code will not produce the output string.  It only produces a 7 character (long) string.
