NAME ^

Authen::Prot - Perl extension for accessing protected password database

SYNOPSIS ^

  use Authen::Prot;

  Authen::Prot::setprpwent();

  $pw = Authen::Prot->getprpwent();

  $pw = Authen::Prot->getprpwuid(0);

  $pw = Authen::Prot->getprpwnam('daemon');

  print "$pw->ufld_fd_name\n";

  $pw->ufld_fd_slogin(time);

  $pw->putprpwnam();

  $crypt = Authen::Prot::bigcrypt('test', 'test'); # not avail on DEC/OSF

  Authen::Prot::endprpwent();

DESCRIPTION ^

The Authen::Prot module provides access to the protected password database via the getprpwent, getprpwuid, getprpwnam, getprpwaid, setprpwent, endprpwent, and putprpwnam system calls available on those Unix systems using the Protected Password database written by SecureWare Inc. (c).

METHODS

The availability of some of the methods below will depend on how the Protected Password database has been implemented on your system.

$crypt = Authen::Prot::bigcrypt($key, $salt)

Encrypted $key using the bigcrypt(3) system call if available and returns the result. Not available on DEC/OSF, via this package yet.

$pw = Authen::Prot::getprpwent()

This method returns a reference to a blessed Authen::Prot object. You may then use this reference to retrieve values of fields in the protected password database. When this method is first called it returns the first entry in the database, on each subsequent call it returns the next entry. See getprpwent(3) for further information on which records are returned.

$pw = Authen::Prot::getprpwuid($uid)

This method returns a reference to a blessed Authen::Prot object if an entry with a uid of that passed is found, otherwise it will return undef. You may then use this reference to retrieve values of fields in the protected password database. See getprpwuid(3) for further information on how records are returned.

$pw = Authen::Prot::getprpwaid($aid)

This method returns a reference to a blessed Authen::Prot object if an entry with a aid of that passed is found, otherwise it will return undef. You may then use this reference to retrieve values of fields in the protected password database. See getprpwaid(3) for further information on how records are returned.

$pw = Authen::Prot::getprpwnam($name)

This method returns a reference to a blessed Authen::Prot object if an entry with a login name of that passed is found, otherwise it will return undef. You may then use this reference to retrieve values of fields in the protected password database. See getprpwnam(3) for further information on how records are returned.

Authen::Prot::setprpwent()

Calling setprpwent effectively rewinds the pointer into the protected password databases so that a subsequent call to getprpwent will return the first record. See setprpwent(3) for further information on the function of this method.

Authen::Prot::endprpwent()

Calling endprpwent effectively closes the protected password database. See endprpwent(3) for further information on the function of this method.

$pw->putprpwnam()

This method commits a Prot object to the protected password database. Setting $pw->uflg_fg_name to 0 will delete the corresponding entry. See putprpwnam(3) for further information on the function of this method.

$pw->pr_struct_field_name() / $pw->pr_struct_field_name($value)

The fields available from the methods described above, depend on the definition of the pr_struct structure in the /usr/include/prot.h on your system, and the information available I have to interpret them. This module will attempt to parse your prot.h file and generate a XS function for each field available on your system. The pr_struct typically consists of four structures given the name of ufld, sfld, uflg and sflg for User fields, System fields, User flags and System flags respectively.

To allow for the syntax differences between C and Perl the field names have been re-written replacing the struct . with a _ in Perl. For example the User field login name would be referenced

in C as:

        ufld.fd_name 

and in Perl as:

        $pw->ufld_fd_name

COPYRIGHT ^

The Protected Password database library by SecureWare Inc. (c) is classified as containing Confidential information so I am unable to include the field descriptions in this document. Please refer to the man pages referenced below and to the /usr/include/prot.h header file for further information.

EXAMPLES ^

The test.pl file provides examples of the methods available via this extension common to most platforms.
