NAME

Authen::SASL::Perl::DIGEST_MD5 - Digest MD5 Authentication class

SYNOPSIS 

  use Authen::SASL qw(Perl);

  $sasl = Authen::SASL->new(
    mechanism => 'DIGEST-MD5',
    callback  => {
      user => $user, 
      pass => $pass,
      serv => $serv
    },
  );

DESCRIPTION

This method implements the client part of the DIGEST-MD5 SASL algorithm, as described in RFC 2831.

This module only implements the auth operation which offers authentication but neither integrity protection not encryption.

CALLBACK

The callbacks used are:

authname
The authorization id to use after successful authentication
user
The username to be used in the response
pass
The password to be used in the response
serv
The service name when authenticating to a replicated service
realm

The authentication realm when overriding the server-provided default. If not given the server-provided value is used.

The callback will be passed the list of realms that the server provided in the initial response.

PROPERTIES

The properties used are:

maxbuf
The maximum buffer size for receiving cipher text
minssf
The minimum SSF value that should be provided by the SASL security layer. The default is 0
maxssf
The maximum SSF value that should be provided by the SASL security layer. The default is 2**31
externalssf
The SSF value provided by an underlying external security layer. The default is 0
ssf
The actual SSF value provided by the SASL security layer after the SASL authentication phase has been completed. This value is read-only and set by the implementation after the SASL authentication phase has been completed.
maxout
The maximum plaintext buffer size for sending data to the peer. This value is set by the implementation after the SASL authentication phase has been completed and a SASL security layer is in effect.
