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 speci-
	 fied 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.
