HibpCheck

This ruby gem is used to check passwords against a list of previously compromised passwords that others have used. It is intended to be extremely light-weight, not depending on anything except Ruby's core libraries.

For more information about the api, see: https://www.troyhunt.com/ive-just-launched-pwned-passwords-version-2/

Add this line to your application's Gemfile:

gem 'hibp_check'

And then execute:

$ bundle

Or install it yourself as:

$ gem install hibp_check

Using this is real easy. Here's an example:

# Call directly with a raw password
HibpCheck.new.password_used 'sekrit1'
# Returns: 33

# Call with a sha1 hash (for 'HelloWorld1')
HibpCheck.new.sha1_used '1924db611f8ae26075212fc9a0d2802e2bf17d3b'
# Returns: 46

HibpCheck.new.password_used 'something.never.seen.before.123.abc.xyz.def.ghi'
# Returns: 0

Those methods will return one of:

• An integer, showing how many times that password has been compromised
• Zero, if not found to have been compromised
• nil or an error raised: if some problem occurred

You can pass a hash of Net::HTTP options when initializing the object that will be used in the http get request. For example:

# Call with timeouts
hc = HibpCheck.new(open_timeout: 1, read_timeout: 1, ssl_timeout: 1)
hc.password_used 'sekrit1'
# Be prepared to rescue timeout errors

You can also inspect the request, response and results of the API request with the following variables which are set on the object:

• params - The hash of params given when the object was initialized
• prefix - the first 5 characters of the SHA1 hash
• remainder - the remaining characters of the SHA1 hash
• request - the Net::HTTP::Get request that was sent
• response - the response, usually Net::HTTPOK
• hashes - the response of remainder hashes from the API, with counts

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.

To run tests, try this:

# After cloning the repo
./bin/setup

rspec spec
