meteor-diceware 2.3.0

A low-resource, easy to use, low latency, customizable and cryptographically secure implementation of Diceware

Meteor Diceware

A low-resource, easy to use, low latency, customizable and cryptographically secure implementation of Diceware which uses a single database which can populate millions of entries for possible words and can easily generate cryptographically strong and secure passwords which one can easily remember.

Installation

python3 -m pip install meteor-diceware

Note: By default, when you run meteor-diceware for the first time, it will install the main wordlist, which is the original diceware wordlist. This is done to have at least one default wordlist to create passphrases from

Other wordlists can be inserted manually through files or via the command line(Check utils

Creating a simple password

Meteor Diceware has a single syntax to go from

python3 -m meteor_diceware -n <noofwords> -d <delimiter> -s <noofspecialcharacters> 

Ex:

$ python3 -m meteor_diceware -n 7 -d _ -s 4 
> D7eferred_Sp%ur_Unifier_Unstamped_Gamma_Episode_/Sp~oof

You can also specify the wordlist with the -w flag. By default, the main wordlist is used(original diceware wordlist). However, you can also create and use other wordlists for your own taste. Check meteor_diceware.utils for the same.

Use cases

It's always advised to use >= 5 words for the password as well as to use >=2 special characters. To establish the same, one can do the following:

Ex:

$ python3 -m meteor_diceware -n 5 -d "_" -s 2 
> For_2Says_For_Ch8aracters_Is  

NOTE :: Please do not use diceware and then make obvious substituions like changing SANA to $^N^. It has been proven time and again that addition, not substitution is what makes a password more cryptographically secure. As in MALO0NE is more secure than MAL0NE

Environment Variable [METEOR_DICEWARE_WORDSET_DEFAULT]

The environment variable METEOR_DICEWARE_WORDSET_DEFAULT can be used to specify the default wordlist to be used for diceware password generation. This can further be modified with the -w option in the CLI

Using utils

meteor_diceware.utils is a bundled accessory which helps generate, edit, delete, concatenate, backup and maintain wordlists.

The following actions can be performed via the utils command-line:

1. python3 -m meteor_diceware.utils create <wordlistname> -w <word1> <word2>... -f <text file to pull words from> : Generate a new wordlist by the name <wordlistname>
2. utils edit <wordlistname> -w <word1> <word2> ... -f <file> : It adds words to an existing database Note: Check more on using the snowflake flag in the file snowflake.pdf or snowflake.md *Note: You can use utils snowflake to print all information about the --snowflake flag on the terminal
3. utils show <wordlistname> : Shows summary and content information of the wordlist
4. utils freeze <wordlistname> -o <file> : Outputs all the words from the wordlist in the text file <file>
5. utils rm <wordlist1> <wordlist2> ... : Remove one or more wordlists from the database
6. utils ls : Lists all the existing wordlists from the database
7. utils cp <wordlist> -t <target> : Copies wordlist to target within the database. Can be used as a backup of some sort
8. utils cat <wordlist1> <wordlist2> .... -t <target> : Concatenates files from all the different wordlists to the target wordlist
9. utils recount <wordlist1> <wordlist2> ... : Rebases and reindexes the wordlists. This counter/index is used internally within the program and is not exposed to the user.
10. utils backup <wordlist1> <wordlist2> ... -o <file> : Creates a copy of the wordlists into a separate SQLite Database file <file>
11. utils restore <file> -W <wordlist1> <wordlist2> --replace : Restores wordlists from a separate file to the main database
12. utils histogram <wordlist> --graphic/--tabular/--output <file> : Creates a length histogram of the words in the wordlist and presents in both tabular and graphic form. Can also be exported to .csv format if -o flag is used.
13. utils scrape <wordlist> --links <link1> <link2> ... : Scrape the links and add the words to the wordlist. Use --responsive flag for responsive pages and use selenium.

Default Files

A text file actual_diceware.txt and an initialized database default.sqlite3 exist within the program. The actual_diceware.txt consists of words from the actual diceware program while the default.sqlite3 is a database which contains the default wordlist and the wordlists mechanism table.

Credits

The following Diceware Words List has been used as-is to create the main wordlist of the program.
