[PATCH 0/2] Use external process to check for passphrase quality

[Damien Goutte-Gattat]

Hi GnuPG folks,

The following patch set provides a way to give the user a better
passphrase quality estimation, as discussed in ticket #2103 [1].

The first patch adds to gpg-agent a new option --passphrase-checker,
which may be set to the pathname of a program that the agent will
call to perform the passphrase quality estimation. The program
should read the passphrase on stdin and write a 0..100 quality
value on stdout. (Such a program is pwscore, from the libpwquality
project [2]).

The second patch changes the behavior of the agent to request a
quality bar from pinentry *only* if either --passphrase-checker
or --check-passphrase-pattern is set, as proposed by Werner.
