__construct (Constructor) [line 678]

void __construct(
[string
$username = null], [string
$challenge = null], [integer
$chapid = 1])

string	`$username`	—	Username
string	`$challenge`	—	8 Bytes Challenge (binary)
integer	`$chapid`	—	Requestnumber

close [line 714]

void close(
)

Frees resources.

Calling this method is always a good idea, because all security relevant attributes are filled with Nullbytes to leave nothing in the mem.

Access: public

Overridden in child classes as:

Auth_RADIUS_MSCHAPv2::close(): Frees resources.

Overrides Auth_RADIUS::close() (Frees resources.)

[ Top ]

putAuthAttributes [line 694]

void putAuthAttributes(
)

Put CHAP-MD5 specific attributes

For authenticating using CHAP-MD5 via RADIUS you have to put the challenge and the response. The chapid is inserted in the first byte of the response.

Overridden in child classes as:

Auth_RADIUS_MSCHAPv1::putAuthAttributes(): Put MS-CHAPv1 specific attributes

Auth_RADIUS_MSCHAPv2::putAuthAttributes(): Put MS-CHAPv2 specific attributes

Overrides Auth_RADIUS_PAP::putAuthAttributes() (Put authentication specific attributes)
