Class: Crypt_CHAP - X-Ref

class Crypt_CHAP

Abstract base class for CHAP

__construct() X-Ref

Constructor

Generates a random challenge
return: void

Crypt_CHAP() X-Ref

No description

generateChallenge($varname = 'challenge', $size = 8) X-Ref

Generates a random binary challenge

param: string $varname Name of the property
param: integer $size Size of the challenge in Bytes
return: void

challengeResponse() X-Ref

Generates the response. Overwrite this.

return: void

Class: Crypt_CHAP_MD5 - X-Ref

class Crypt_CHAP_MD5

Generate CHAP-MD5 Packets

challengeResponse() X-Ref

Generates the response.

CHAP-MD5 uses MD5-Hash for generating the response. The Hash consists
of the chapid, the plaintext password and the challenge.

return: string

Class: Crypt_CHAP_MSv1 - X-Ref

class Crypt_CHAP_MSv1

Generate MS-CHAPv1 Packets. MS-CHAP doesen't use the plaintext password, it uses the
NT-HASH wich is stored in the SAM-Database or in the smbpasswd, if you are using samba.
The NT-HASH is MD4(str2unicode(plaintextpass)).
You need the hash extension for this class.

__construct() X-Ref

Constructor

Loads the hash extension
return: void

Crypt_CHAP_MSv1() X-Ref

No description

ntPasswordHash($password = null) X-Ref

Generates the NT-HASH from the given plaintext password.

return: string

str2unicode($str) X-Ref

Converts ascii to unicode.

return: string

challengeResponse() X-Ref

Generates the NT-Response.

return: string

ntChallengeResponse() X-Ref

Generates the NT-Response.

return: string

lmChallengeResponse() X-Ref

Generates the LAN-Manager-Response.

return: string

_challengeResponse($lm = false) X-Ref

Generates the response.

Generates the response using DES.

param: bool $lm wether generating LAN-Manager-Response
return: string

lmPasswordHash($password = null) X-Ref

Generates the LAN-Manager-HASH from the given plaintext password.

return: string

_desHash($plain) X-Ref

Generates an irreversible HASH.

return: string

_desAddParity($key) X-Ref

Adds the parity bit to the given DES key.

param: string $key 7-Bytes Key without parity
return: string

response($lm = false) X-Ref

Generates the response-packet.

param: bool $lm wether including LAN-Manager-Response
return: string

Class: Crypt_CHAP_MSv2 - X-Ref

class Crypt_CHAP_MSv2

Generate MS-CHAPv2 Packets. This version of MS-CHAP uses a 16 Bytes authenticator
challenge and a 16 Bytes peer Challenge. LAN-Manager responses no longer exists
in this version. The challenge is already a SHA1 challenge hash of both challenges
and of the username.

__construct() X-Ref

Constructor

Generates the 16 Bytes peer and authentication challenge
return: void

ntPasswordHashHash($nthash) X-Ref

Generates a hash from the NT-HASH.

param: string $nthash The NT-HASH
return: string

challengeHash() X-Ref

Generates the challenge hash from the peer and the authenticator challenge and
the username. SHA1 is used for this, but only the first 8 Bytes are used.

return: string

challengeResponse() X-Ref

Generates the response.

return: string
