A password manager for paranoids.
Kyle differs from other password managers, since:
- It doesn't store any passwords so there is nothing to steal/crack for attackers.
- However, you can't store any given password, but must set one generated by Kyle.
Kyle differs from other password generators, since:
-
Generated passwords are not random, but a brute-force method can take thousands of years to crack one:
e.g. on the test vectors Bill Gates' password tooks 12.11 seconds on a MacBook Pro Early 2013 with 2,4 GHZ Intel Core i7. So even for a lazy master-key with 8 chars includes small-case-letters and numbers, there are
36^8+36^7+36^5+36^4+36^3+36^2+36 = 2901713047668combinations; with 12.11s per combination, it would take 1,114,274 years to try all combinations. -
It doesn't use any specific hash or encryption algorithm, using a mixture of several, chosen using the input info and key.
$ gem install kyleJust type kyle on the command line to run, and pick any password depending
on your favourite animal.

$ kyle abc.com superuser 80 jackal
Key:
+zhRwHPWCHknxlZpArguments must in this order, but any missing ones will be prompted for.
Adding the -c flag will prompt for the key twice, so you can be sure you
didn't make a typo.
Adding the -r flag saves the hostname/account/port combination in ~/.kyle.
Adding -a flag lets you choose from one of savedhost/account/port records saved with -r;
$ kyle -b path/to/file.kyle animal
Key:
hostname:account:port (animal) = password
hostname:account:port (animal) = passwordWhere file.kyle contains triples of hostname, account, port separated by
semi-colons (;), one per line. E.g.:
facebook.com;zuckerberg;80
amazon.com;bezos;443
-
Merge version with Isaac Seymour's efforts to unify multiple development lines that includes;
-
Refactored code to have proper Rspec tests, and respect Rubocop conventions
-
Added ability to specify hostname, account, port, and animal as args to the executable
-
- Added -a (Auto) flag
-
Added -b (BATCH) mode which help you generate bulk passwords;
-
Added -r option to add entered values to <USER_HOME>/.kyle file
