使用

先看后面的安装，Python脚本保存为SecureCRTDecrypt.py
用法
python SecureCRTDecrypt.py [filename...]
例子

      [@bx_5_219 /tmp]# python SecureCRTDecrypt.py 10.10.123.123.ini
      10.10.123.123.ini
      ssh root@10.10.70.30 # I'mpassword
  
 

依赖包

安装解密依赖包pycrypto
下载

      https://pypi.python.org/pypi/pycrypto
      wget https://pypi.python.org/packages/source/p/pycrypto/pycrypto-2.6.1.tar.gz
  
 

解压安装

      tar -zxvf pycrypto-2.6.1.tar.gz
      cd pycrtyto-2.6.1
      python setup.py build
      python setup.py install
  
 

密文解密程序

保存为SecureCRTDecrypt.py

      from Crypto.Cipher import Blowfish
      import argparse
      import re
      def decrypt(password) :

          c2 = Blowfish.new('24 A6 3D DE 5B D3 B3 82 9C 7E 06 F4 08 16 AA 07'.replace(' ','').decode('hex'), Blowfish.MODE_CBC, '\x00'*8)
          padded = c1.decrypt(c2.decrypt(password.decode('hex'))[4:-4])

              p += padded[:2]
              padded = padded[2:]
         return p.decode('UTF-16')
      REGEX_HOSTNAME = re.compile(ur'S:"Hostname"=([^\r\n]*)')
      REGEX_PASWORD = re.compile(ur'S:"Password"=u([0-9a-f]+)')

         return ''

         if m :
             return m.group(1) + '@'
         return ''
      parser = argparse.ArgumentParser(description='Tool to decrypt SSHv2 passwords in VanDyke Secure CRT session files')
      parser.add_argument('files', type=argparse.FileType('r'), nargs='+',
         help='session file(s)')
      args = parser.parse_args()
      for f in args.files :
          c = f.read().replace('\x00', '')
         print f.name
         print "ssh %s%s%s # %s"%(port(c), username(c), hostname(c), password(c))
