📘 NAME

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

🚀 Quick Reference

Use Case	Command	Description
🌐 Create a DIGEST-MD5 SASL client object	use Authen::SASL qw(Perl); $sasl = Authen::SASL->new(mechanism => 'DIGEST-MD5', callback => { user => $user, pass => $pass, serv => $serv });	Instantiate a SASL client for DIGEST-MD5 authentication with required callbacks
🔑 Set client callbacks	$sasl->callback(user => $user, pass => $pass, realm => $realm);	Assign or override authentication credentials and realm
🛡️ Configure security properties	$sasl->property(minssf => 128, maxbuf => 65536);	Set minimum SSF, buffer size, etc. for the SASL security layer
🔐 Server-side password lookup	getsecret($username, $realm, $authzid)	Callback that returns the password for a given username and realm

📝 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 and server parts of the DIGEST-MD5 SASL algorithm, as described in RFC 2831.

🔑 CALLBACK

The callbacks used are:

• client
  • authname — The authorization id to use after successful authentication
  • user — The username to be used in the response
  • pass — The password to be used to compute 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.
• server
  • realm — The default realm to provide to the client
  • getsecret(username, realm, authzid) — Returns the password associated with username and realm

⚙️ 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.
