sympa-upgrade-password(1)	 sympa 6.2.76	     sympa-upgrade-password(1)

NAME
       sympa-upgrade-password -	Upgrading password in database

SYNOPSIS
	 sympa upgrade password	[--dry_run|-n] [--debug|d] [--verbose|v] [--config file	] [--cache file] [--nosavecache] [--noupdateuser] [--limit|l number_of_users]

OPTIONS
       --dry_run|-n
	   Shows  what	will  be  done	but  won't  really perform the upgrade
	   process.

       --debug|-d
	   Print additional debugging information during the upgrade process.

       --verbose|-v
	   Print verbose logging messages during the upgrade process.

       --config	FILENAME
	   Specify the pathname	of the file to use as the Sympa	 configuration
	   file.   Otherwise  the  system  default Sympa configuration file is
	   used.

       --cache FILENAME
	   Specify the pathname	of a file to store  precalculated  hashes  for
	   reuse on subsequent runs of the script.

	   The file is created if it does not already exist.

	   This	option is useful for large sites using intentionally expensive
	   password hashes such	as bcrypt. In that case	this script can	be run
	   in  advance	to  precalculate  hashes  and reduce the time required
	   during the final upgrade process.

	   WARNING: since it  contains	sensitive  password  data,  this  file
	   should  be  protected as carefully as any other password file, or a
	   database dump of the	Sympa user_table.

       --nosavecache
	   Disables updates of the cache. The  cache  is  still	 consulted  if
	   specified with "--cache".

       --noupdateuser
	   Disables   updates	of   the   user_table.	 Mostly	  useful  when
	   precalculating user hashes in advance.

DESCRIPTION
       Versions	later  than  5.4  use  one-way	hashes	instead	 of  symmetric
       encryption  to  store  passwords.  This	script	upgrades any symmetric
       encrypted passwords it finds to one-way hashes.

       Versions	later than 6.2.26 support bcrypt.

       This upgrade  requires  to  rewriting  user  password  entries  in  the
       database.  This upgrade IS NOT REVERSIBLE.

HISTORY
   Password storage
       As  of  Sympa  3.1b.7,  passwords  may  be  stored into user table with
       encrypted form by reversible RC4.

       Sympa 5.4 or later uses	MD5  one-way  hash  function  to  encode  user
       passwords.

       Sympa 6.2.26 or later has optional support for bcrypt.

   Utilities for upgrading passwords
       "sympa.pl --md5_encode_password"	appeared on Sympa 6.0.

       It was obsoleted	by upgrade_sympa_password.pl on	Sympa 6.2.

       Its  function  was  moved  to  "sympa upgrade password" command line on
       Sympa 6.2.71b.

6.2.76				  2025-02-03	     sympa-upgrade-password(1)
