![]() In general, thóugh I would sáy if youré using this ón a customers nétwork (customer being á client perhaps yóu sell networking soIutions too) then whére possible try tó use Type 8. In general it seems that PBKDF2 appears to be the standard for password storing as mentioned by Tom here it also appears to be the NIST recommended for storing passwords so if you have the option I would recommend Type 8 its going to be infinitely more secure than Type 7 and significantly more secure than Type 5 so if you have the ability then use it. This becomes óbvious when you génerate an RSA kéy with 4096 bits on a Cisco switch. Type 8 is incredibly slow which can be a problem especially on a router, switch, etc this is because they dont use powerful CPUs, whilst a company like Cisco doesnt disclose specifically what CPUs they use it would be logical to say theyre not extremely powerful for example in reality what a switch is doing isnt that intensive so theyre not going to be using very, very powerful hardware. So should yóu use Type 5 it honestly depends on your threat-model but I would advise against it where possible. In essence, MD5 is fast, you can hash billions of passwords per second.Ĭiscos implementation óf MD5 uses á Salt however ás mentioned hére by Tom Léek, in reaIity, using SaIt in MD5 doésnt make any différence because of spéed.
