= How to retrieve pickled data =

If data is in "motpy.pickle" and salt is "salt" and the host we search for
is the first item then

--- cut ---
def decrypt(salt, ciphertext):
        from Crypto.Cipher import AES
        import re
        re_code = re.compile(
            "^\{(?P<version>\d+)\}\{(?P<iv>.{" + str(AES.block_size) + \
            "})\}(?P<chipertext>.*)$")
        c = re_code.search(ciphertext)
        if c:
            code_version = c.group('version')
            iv = c.group('iv')
            ciphertext = c.group('chipertext')
        else:
            code_version = '1'
            iv = salt
            ciphertext = ciphertext
        if code_version == '1':
            try:
                encobj = AES.new(salt, AES.MODE_CFB)
            except:
                encobj = AES.new(salt, AES.MODE_CFB, iv)
        elif code_version == '2':
            encobj = AES.new(salt, AES.MODE_CFB, iv)
        else:
            sys.exit(10)
        plaintext = encobj.decrypt(ciphertext)
        return plaintext

salt='salt............'
