10 | * CMDHELP: Usage: challengeauth <username> <response> <hmac algorithm> |
11 | * CMDHELP: Authenticates using challenge response. | |
12 | * CMDHELP: To generate the response from the challenge, calculate the following: | |
13 | * CMDHELP: HMAC(challenge){k} | |
14 | * CMDHELP: where HMAC is the hash message authentication code as described in | |
15 | * CMDHELP: RFC 2104, k is HEXDIGEST(<lower case username>:HEXDIGEST(<password>)) | |
16 | * CMDHELP: and HEXDIGEST is the hash function used in the MAC construction. | |
