4.7.6 Managing user passwords

Older versions of GNATS, up to and including version 3.x, stored user passwords in plaintext in the ‘gnatsd.user_access’ files. Version 4 has the options of storing the password as MD5 or standard DES crypt() hashes (as most UNIX versions do in the system password files) as well as in plaintext. Since the password strings require a prefix to indicate how they are encrypted, one is forced to convert the old password files to a new format when upgrading to GNATS version 4. See section Upgrading from older versions.

The gnats-pwconv tool takes care of converting the old password files to the new format:

gnats-pwconv [ -c | --crypt ] [ -m | --md5 ] [ -p | --plaintext ]
         [ -h | --help] [ -V | --version ] INFILE [OUTFILE]

Unless the --version or --help options are given, exactly one encryption method must be specified, as well as an input file. The output file parameter is optional. If one is not specified, results will be printed on standard output.
