.SH "NAME"
Authen::SASL::Perl::DIGEST_MD5 \- Digest MD5 Authentication class
.SH "SYNOPSIS"

\&  $sasl = Authen::SASL->new(
\&    mechanism => 'DIGEST-MD5',

.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This method implements the client part of the \s-1DIGEST\-MD5\s0 \s-1SASL\s0 algorithm,
as described in \s-1RFC\s0 2831.
.PP
This module only implements the \fIauth\fR operation which offers authentication
but neither integrity protection not encryption.
.Sh "\s-1CALLBACK\s0"
.IX Subsection "CALLBACK"
The callbacks used are:
.IP "authname" 4
.IX Item "authname"
The authorization id to use after successful authentication
.IP "user" 4
.IX Item "user"
The username to be used in the response
.IP "pass" 4
.IX Item "pass"
The password to be used in the response
.IP "serv" 4
.IX Item "serv"
The service name when authenticating to a replicated service
.IP "realm" 4
.IX Item "realm"
The authentication realm when overriding the server-provided default.
If not given the server-provided value is used.
.Sp
The callback will be passed the list of realms that the server provided
in the initial response.
.Sh "\s-1PROPERTIES\s0"
.IX Subsection "PROPERTIES"
The properties used are:
.IP "maxbuf" 4
.IX Item "maxbuf"
The maximum buffer size for receiving cipher text
.IP "minssf" 4
.IX Item "minssf"
The minimum \s-1SSF\s0 value that should be provided by the \s-1SASL\s0 security layer.
The default is 0
.IP "maxssf" 4
.IX Item "maxssf"
The maximum \s-1SSF\s0 value that should be provided by the \s-1SASL\s0 security layer.
The default is 2**31
.IP "externalssf" 4
.IX Item "externalssf"
The \s-1SSF\s0 value provided by an underlying external security layer.
The default is 0
.IP "ssf" 4
.IX Item "ssf"
The actual \s-1SSF\s0 value provided by the \s-1SASL\s0 security layer after the \s-1SASL\s0
authentication phase has been completed. This value is read-only and set
by the implementation after the \s-1SASL\s0 authentication phase has been completed.
.IP "maxout" 4
.IX Item "maxout"
The maximum plaintext buffer size for sending data to the peer.
This value is set by the implementation after the \s-1SASL\s0 authentication
phase has been completed and a \s-1SASL\s0 security layer is in effect.
