## NAME
    [Authen::SASL::SASLprep](https://www.chedong.com/phpMan.php/perldoc/Authen%3A%3ASASL%3A%3ASASLprep/markdown) - A Stringprep Profile for User Names and Passwords (RFC 4013)

## SYNOPSIS
      use [Authen::SASL::SASLprep](https://www.chedong.com/phpMan.php/perldoc/Authen%3A%3ASASL%3A%3ASASLprep/markdown);
      $output_query = saslprep $input;
      $output_stored = saslprep $stored;

## DESCRIPTION
    This module implements the *SASLprep* specification, which describes how to prepare Unicode
    strings representing user names and passwords for comparison. SASLprep is a profile of the
    stringprep algorithm.

## FUNCTIONS
    This module implements a single function, "saslprep", which is exported by default.

### saslprep
        Processes $input according to the *SASLprep* specification and returns the result.

        If $input contains characters not allowed for *SASLprep*, it throws an exception (so use
        "eval" if necessary).

        If the boolean parameter $stored is true, an exception is also thrown when characters are
        not allowed for stored strings (i.e., when characters are unassigned in Unicode 3.2). The
        default is to prepare query strings, in which unassigned characters are allowed.
