The network used by a printing company uses a mixture of Windows, SUSE Linux OS and UBUNTU OS (as outlined in the original description). The network allows the "sharing" of password information for administrative reasons (it makes the management very easy to handle) and thus all the systems need to have agreement on the password hashing algorithm to be used. The hashing schemes used are DES56, MD5 and Blowfish. Specify which hashing scheme would be used overall and explain how effective this security setup is overall
