Removing password from PDF files

Posted on by perlancar

Electronic billing statement is great. Paperless, easier to archive, and you don't need to care if you leave the house for a month or move addresses. But what's the most irritating thing about credit card e-statements? That the banks decide to encrypt the PDF with some easy-to-guess password like YYYYMMDD of your birth date, or FirstNameDDMMYY, or some other variation. But each bank picks a different password, naturally.

So the first thing I do after downloading an e-statement is to run them through my remove-pdf-password script. It's basically a wrapper for "qpdf" and will try a series of passwords, then decrypt the PDF in-place. You put the passwords in ~/.config/remove-pdf-password.conf, e.g.: 

passwords = PASS1  ; anz
passwords = PASS2  ; hsbc
passwords = PASS2  ; uob
...

The script is distributed with the App::PDFUtils distribution. There's the counterpart script in the distribution, add-pdf-password, in case you want to return the favor. The next time some bank staff requests your documents, you can send them in an email encrypted. In the email you write, "the password is the name of the bank followed by the phone number of the bank, but replace every f with f*ckyou …"

Quickly generate CSV or TSV from SQL query

Posted on by perlancar

Sometimes to produce CSV or TSV from information in a MySQL database, all you have to do is: 

echo 'some SELECT query ...' | mysql mydb >data.tsv

but for more complex things, you'll often need to use scripting like with Perl to do some munging first. When you're ready to output the data with: 

$sth->fetchrow_arrayref
$sth->fetchrow_hashref

the data is in a Perl data structure. How to quickly output CSV? I've looked at DBI::Format and DBIx::CSVDumper and they are cumbersome especially if you want something brief for one-liners: you need to instantiate a separate object with some parameters, then call an additional one or more methods. You might as well just do this with the standard Text::CSV (or Text::CSV_XS): 

use Text::CSV;
my $csv = Text::CSV->new;

...
$csv->print(\*STDOUT, $sth->{NAME});
while (my $row = $sth->fetchrow_arrayref) {
     $csv->print(\*STDOUT, $row);
}

For TSV it's even shorter (note: fail spectacularly when data contains Tab character, but that is relatively rare): 

say join("\t", @{$sth->{NAME}});
while (my $row = $sth->fetchrow_arrayref) {
     say join("\t", @$row);
}

My modules DBIx::CSV and DBIx::TSV attempt to offer something even briefer (for CSV, at least). Instead of fetchrow_arrayref or fetchall_arrayref (or selectrow_arrayref, selectall_arrayref), you use fetchrow_csv and friends: 

print $sth->fetchall_csv;

This automatically prints the header too, and if you don't want header: 

print $sth->fetchall_csv_noheader;

For even more text table formats, like ASCII table, Org table, Markdown table, and so on, I've also written DBIx::TextTableAny.

I've also just written DBIx::Conn::MySQL after being tired from writing the gazillionth one-liner to connect to MySQL database. Now, instead of: 

% perl -MDBI -E'my $dbh = DBI->connect("dbi:mysql:database=mydb", "username", "password"); $sth = $dbh->prepare(...)'

you can now write this: 

% perl -MDBI::Conn::MySQL=mydb -E'$sth = $dbh->prepare(...)'

Clumping

Posted on by perlancar

This post is a "thinking out loud" post, about an unimplemented feature I'm planning.

The problem

The most often complaint I get when I release a Perinci::CmdLine -based Perl application is the huge dependencies of Perinci::CmdLine (currently Perinci::CmdLine::Lite only has 24 direct non-core dependencies, but recursively it has 98 non-core dependencies in 92 unique distributions). By the way, you can produce these numbers "very easily" using lcpan and td: 

% lcpan mods -lx Perinci::CmdLine::Lite
+------------------------+---------+-------------------------------------------------------+----------------------+-----------+----------------------+---------+
| module                 | version | abstract                                              | dist                 | author    | rel_mtime            | is_core |
+------------------------+---------+-------------------------------------------------------+----------------------+-----------+----------------------+---------+
| Perinci::CmdLine::Lite | 1.812   | A Rinci/Riap-based command-line application framework | Perinci-CmdLine-Lite | PERLANCAR | 2018-05-01T08:42:19Z | 0       |
+------------------------+---------+-------------------------------------------------------+----------------------+-----------+----------------------+---------+

% lcpan deps Perinci::CmdLine::Lite --noinclude-core | wc -l
24
% lcpan deps Perinci::CmdLine::Lite --noinclude-core -R | wc -l
98
% lcpan deps Perinci::CmdLine::Lite --noinclude-core -R --flatten | \
    td select module | lcpan mod2dist | td select value | sort | uniq | wc -l
92

Sort of ironic because years ago I used to mock Moose 's high number of dependencies and avoid it like the plague, and then ending up creating the same situation with my own distribution. Correction: a much worse situation than the current Moose:

I arrange the modules into many distributions because I am trying to keep things modular. So when I only need a specific subset of functionality, I don't have to pull the whole thing (and along with it its large list of dependencies). Maybe I went overboard? Maybe. Nevertheless.

The high number of dependencies presents an inconvenience and annoyance when users want to install my application, especially since CPAN clients like cpan and cpanm default to testing distributions before installing them.

One solution: Perinci::CmdLine::Inline

One solution I created for this problem is Perinci::CmdLine::Inline (PC:Inline) which basically "pre-assembles" the application with sort of a "mini", "embedded" Perinci::CmdLine during distribution build time, so that when a user installs the application she doesn't need to get Perinci::CmdLine anymore. This also has another benefit of faster application startup time due to the "pre-assembling" thingy. But this pre-assembling has some downsides too. Whenever I create a new version of PC:Inline, I will have to rebuild all the applications again. PC:Inline also does not (read: will not, because of the lack of Riap layer) have all the features of a proper Perinci::CmdLine. I use PC:Inline only for simpler applications that need to be very light (has no non-core dependencies, or starts fast) like hr, wordlist, zodiac-of.

Another solution: fatpacking, datapacking

Another solution is fatpacking or datapacking. I've tried this in the past with the pause script, and it works rather well. Except that when it comes to packaging the CPAN distribution as a Debian package, the Debian policy forbids "convenience copies" of code.

Past solution: lumping

Yet another solution which I've tried in the past is what I call "lumping": in a lump distribution I include modules from other distributions (the dependencies) but leave them unindexed. For example, I created a distribution called Perinci-CmdLine-Any-Lumped that contains modules from Perinci-CmdLine-Any (Perinci::CmdLine::Any) as well as all its recursive pure-perl non-core dependencies, like Data::Sah, Data::Sah::Coerce, and so on. After installing just one lump distribution, a user will have perhaps 100+ extra (but "hidden") modules from various distributions on her system. The perl interpreter will see those extra modules fine. The modules are "hidden" only in the sense that the original distributions of those modules are not listed as installed (because they aren't).

I abandoned this solution because it feels really dirty. The extra modules lumped into the lump distribution are actually "orphan" modules because the lump distribution does not publicly confess that it includes the modules. And I'm pretty sure lump distributions are not good candidates for Debian perl packages, but it's okay.

Another proposed solution: clumping

This post will describe another solution which I'm thinking of (with an equally stupid name so if the idea ended up being really stupid, the name would have already fitted): clumping.

A clump distribution is named "Clump-SOMETHING" and will contain modules from several other distributions (called "source distributions"). The purpose of a clump distribution is to package several other distributions as a single distribution for the purpose of reducing the number of dependencies for the end-user.

For example, a clump distribution called "Clump-Data-Sah" will contain modules from Data-Sah as well as Data-Sah-Coerce, Data-Sah-Format, and so on.

Dist::Zilla::Plugin::Clump

To help build this distribution, a Dist::Zilla plugin will be created and used: DZP:Clump. To use this plugin, we list the source distributions that we want to include: 

[Clump]
include=Data-Sah
include=Data-Sah-Coerce
include=Data-Sah-Format
...

The plugin will gather module files from the source distributions as well as merge the dependencies from the source distributions into the dependencies for the clump distribution.

Dependencies that end up being in the clump distribution can be "netted out". For example, Data-Sah depends on Data::Sah::Coerce which is in the Data-Sah-Coerce distribution which is also another source distribution in the clump, so this dependency now does not need to be specified in Clump-Data-Sah.

Clumping and module versions

The version number of a module inside the clump distribution will be the original version joined by ".0". So for example, if the original version number of module M1 is "0.001" then M1's version number in the clump distribution is "0.001.0". If M2's original version is "0.1.2" then M2's version in the clump is "0.1.2.0" and so on. As far as perl concerns the two version numbers in each case are the same: 

version->parse("0.001") == version->parse("0.001.0")
version->parse("0.1.2") == version->parse("0.1.2.0")

The module version will have to be checked to satisfy the above relationship and if it does not, a new release will need to be made in the source distribution first to remedy this. For example, M3's original version is 0.02. If we append ".0" to it to become "0.02.0" then the new version will be less than the original version: 

version->parse("0.02") > version->parse("0.02.0")
# because 0.02   is 0.020
# and     0.02.0 is 0.002.0

To include M3 in the clump, we will need to make a new release of M3 in the original source distribution first, say of version 0.030. Then M3 version 0.030 can now be included in the clump, as version 0.030.0.

Yes, this means the clump distribution will contain different version numbers. Which is usually not recommended for a "normal" Perl distribution but is appropriate here.

Clumping and the PAUSE indexer

When the clump distribution is released, PAUSE will index the clump distribution and now modules included in the clump will be indexed as belonging to the clump distribution instead of their original distribution.

When user installs one of these modules, she will be getting it (and automatically a lot of other modules too) from the clump distribution, thus reducing the number of distributions she needs to install to satisfy all the dependencies of an application.

Developing modules that are included in clumps

Ideally, modules are still developed in its original source distribution, e.g. Data::Sah::Coerce in Data-Sah-Coerce. When I want to release a new version of Data::Sah::Coerce, I can just release a new version of Data-Sah-Coerce. Now the module will be indexed by PAUSE as belonging to the new Data-Sah-Coerce.

As more and more modules are being "unclumped" as new releases of the source distributions come along, the level of inconvenience to end-users will once again increase. To remedy this, from time to time I can release a new clump distribution again that contains newer "snapshots" of modules.

This is the reason why version of modules in the clump is being kept the same (albeit with extra ".0"): so version bump in the original source distribution will be able to "eclipse" the clumped version on CPAN later. Even when the original distribution bumps using an extra subversion, e.g. 0.001 to 0.001.1 it will still eclipse the clumped version. The next clumped version will be 0.001.1.0.

Clumping vs lumping

This clump solution is cleaner than the lumping solution because in the former case, no modules are "hidden". Basically clumping is lumping, but the included modules are "acknowledged" and properly indexed. The $orig_version . ".0" thing is really the only novel element here. Because the modules are now not hidden, their dependencies must now also be handled.

As to Debian packaging, the source distributions and not the clump distribution are the ones that will be packaged so there should not be an issue with "convenience copies" or "bundling".

Generating random passwords according to patterns with genpw

Posted on by perlancar

There are several modules on CPAN for generating random passwords, but last time I checked, none of them are flexible enough. Different websites or applications have different requirements (sometimes ridiculous ones) for passwords. True, most modules allow setting minimum/maximum length, and some of them allow customizing the number of special characters, or number of digits, but what I want is some sort of template/pattern that the generator would follow. So I created genpw.

Basic functionality

genpw is your usual random password generator CLI. When run without any arguments, it returns a single random password (8-20 characters long, comprising letters/digits): 

% genpw
J9K3ZjBVR

To return several passwords: 

% genpw 5
wAYftKsS
knaY7MOBbcvFFS3L1wyW
oQGz62aF
sG1A9reVOe
Zo8GoFEq

To set exact length or minimum/maximum of length: 

% genpw -l 4
1CN4

% genpw --min-len 12 --max-len 14
nqBKX5lyyx7B

Patterns

In addition to the above basic customization, genpw allows you to specify a pattern (or several patterns to pick randomly, for that matter). A pattern is a string that is similar to a printf pattern where conversion sequences like %d will be replaced with actual random characters. Here are the available conversions: 

%l   Random Latin letter (A-Z, a-z)
%d   Random digit (0-9)
%h   Random hexdigit (0-9a-f)
%a   Random letter/digit (Alphanum) (A-Z, a-z, 0-9; combination of %l and %d)
%s   Random ASCII symbol, e.g. "-" (dash), "_" (underscore), etc.
%x   Random letter/digit/ASCII symbol (combination of %a and %s)
%m   Base64 character (A-Z, a-z, 0-9, +, /)
%b   Base58 character (A-Z, a-z, 0-9 minus IOl0)
%B   Base56 character (A-Z, a-z, 0-9 minus IOol01)
%%   A literal percent sign
%w   Random word

You can specify %NC (where N is a positive integer, and C is the conversion) to mean a sequence of random characters (or a random word) with the exact length of N. Or %N$MC (where N and M are positive integers) to mean random characters (or word) with length between N and M.

Unsupported conversion will be unchanged, like in printf.

Some examples:

Generate random digits between 10 and 12 characters long: 

% genpw -p '%10$12d'
55597085674

Generate a random UUID: 

% genpw -p '%8h-%4h-%4h-%4h-%12h'
ff26d142-37a8-ecdf-c7f6-8b6ae7b27695

Like the above, but in uppercase: 

% genpw -p '%8h-%4h-%4h-%4h-%12h' -U
22E13D9E-1187-CD95-1D05-2B92A09E740D

Words

The %w conversion in pattern mean to replace with a random word. Words are fetched from STDIN (and will be shuffled before use). For example, the command below will generate password in the form of a random word + 4 random digits: 

% genpw -p '%w%4d' < /usr/share/dict/words
shafted0412

Instead of from STDIN, you can also fetch words from the various WordList::* modules available on CPAN (and installed locally). A separate CLI provides this functionality: genpw-wordlist, which is basically just a wrapper to extract the words from the wordlist module(s) then feed it to App::genpw. By default, if you don't specify -w option(s) to select wordlist modules, the CLI will use WordList::EN::Enable: 

% genpw-wordlist -p '%w%4d'
sedimentologists8542

Generate 5 passwords comprising 8-character word followed by between four to six random digits: 

% genpw-wordlist 5 -p '%8w-%4$6d'
alcazars-218050
pathogen-4818
hogmanes-212244
pollened-3206
latinity-21053

Configuration file

To avoid you from having to type patterns again and again, you can use a configuration file. For example, put this in $HOME/genpw.conf: 

[profile=uuid]
patterns = %8h-%4h-%4h-%4h-%12h
case = upper

then you can just say: 

% genpw -P uuid
7B8FB8C6-0D40-47A3-78B7-848A114E5C6D

Speed

The speed is not great, around 2000 passwords/sec on my laptop, though I believe this should not matter for most use-cases.

Closing

genpw is a flexible random password generator where you can specify patterns or templates for the password. I'm still working on a few things, like how to enable secure random source in the most painless way. There are also various CLI variants to generate specific kinds of passwords as straightforward as possible: genpw-base56, genpw-base64, genpw-id, and the aforementioned genpw-wordlist.
