usage: Check Session ID Entropy Bit [-h] [-s SID] [-v]

Check Session ID Entropy Bit

optional arguments:
  -h, --help            show this help message and exit
  -s SID, --session SID

2. Session ID Entropy Check

$ python csid.py -s a00a0a100203
### Session ID Check Entropy ###
+ Session ID : a00a0a100203
+ String Length : 12
+ Characters : 36 Type
+ Strength : 62.0 Bits
+ Result : Vulnerable(At least 128 Bits)

$ python csid.py -s 1a44f079183C8492d55805ef18f1079b0357c8d6                                                                
### Session ID Check Entropy ###
+ Session ID : 1a44f079183C8492d55805ef18f1079b0357c8d6
+ String Length : 40
+ Characters : 62 Type
+ Strength : 238.2 Bits
+ Result : Good

3. 결과값 설명

   • Session ID : 입력한 Session ID(세션 ID)
   • String Length : Session ID 값의 길이
