What is the different between those 2?
enable password and enable secret?

I often see that enable password 7 <password>
what is the number stand for? Based on my research 7 is a weak encryption algorithim? why they don't use the strongest one?
say enable password 5 <passsword>

Enable secret uses "5". You are correct in what those numbers mean in terms of the encryption level. Regular enable password is a reversible encryption, enable secret is not reversible. There are plenty of utilities out there to decrypt the former for you. this isn't always a bad thing- If you break into a router and need to get the password without changing it, it's helpful. But for best security, always use enable secret.

Might want "service password encryption" too

That is what activates that reversible encryption. Without it, everything but enable secret will be in clear text.

Is that possible to have enable password 5 <password>?
I don't understand whether "5" is always combine with "secret" ? or can it be combine with any other number? any references for this?

No, it isn't. IOS puts it in there as a reference when it reads the password so it knows how to interpret it.

Mike has it all, So just to add;

7 means MD7 and 5 means MD5

There are so many sites/programs out there which will decrypt an MD7 password in seconds.

Cheers,
Rajesh
