What is the password format in backup file

[whoo]

Hi,

I'm trying to find hash format of configfile.

[ul]AK1XXXXX >> FortiGate

SH2XXXXX >> FortiGate256[/ul]

But impossible to find format for password:

config user local
    edit "XXXX"
        set type password
        set passwd ENC 8bU{...}0AiaPwg==. 
    next
end

 Thanks

Regards,

W.
