variance

What command would you use to enter the following information:

Secret: password123

Note: NO encryption (Unencrypted)

enable secret 0 password123

You enter the command:

"enable password 7 password123"

You get the error:

"Invalid encrypted password: password123"

Why did you receive this error?

7 specifies a "Hidden" password will follow. Must already be encrypted.

Ex. enable password 7 08314D5D1A0E0A05165A5E57

When would you enter the command then receive an error:

Command: "enable secret 5 password123"

ERROR: "The secret you entered is not a valid encrypted secret.

To enter an UNENCRYPTED secret, do not specify type 5 encryption.

When you properly enter an UNENCRYPTED secret, it will be encrypted.

Why did you receive this error?

Secret must be an MD5 hash.

Ex. $1$cf6N$Ugo.y0cxMLffTfQtyO/Xt.
