Based on the username global configuration mode command displayed in the exhibit. What does the option secret 5 indicate about the enable secret password?
It is encrypted using DH group 5.
B.
It is hashed using SHA.
C.
It is hashed using MD5.
D.
It is encrypted using a proprietary Cisco encryption algorithm.
Explanation:
When it comes to usernames, the options are plain-text, encrypted, or hashed. If the
command “username cisco password C1$C0” is used, the output will show the actual
plain-text password. The ability to encrypt this password requires the use of the “service
password-encryption” command. Now the same password will appear encrypted, with a
“7” in front of it to indicate cisco proprietary encryption. The “secret” is different…
secrets are hashed, and the hashing algorithm used by cisco is MD5.Incorrect :
A: DH is not used by cisco for encrypting or hashing passwords in the IOS.
B: SHA is not employed by cisco in it’s hashing functions
D: Cisco does not have a proprietary hashing algorithm… it uses MD5.
