# Fancy Logger An easily customizable logger with style. ## Install ### Bundler: `gem 'fancy_logger'` ### RubyGems: `gem install fancy_logger` ## Usage Simply use as if you were using the normal Ruby `Logger` class: ```ruby require 'fancy_logger' logger = FancyLogger.new(STDOUT) logger.info "Hello" ``` ### Config The `config` instance method allows you to modify the configuration of the Logger within a DSL. Continuing with our last example: ```ruby logger.config do timestamp_format "%c" styles do info do foreground :yellow blink true end end end logger.debug 'Look here!' logger.info 'Doing things...' logger.warn 'Watch out!' logger.error 'Bad' logger.fatal 'VERY bad' logger.unknown 'Weird unknown stuff' ``` #### Output ![][output_example] ### Config ```ruby # The format of the timestamp in the log. Follows the strftime standards. timestamp_format "%F %r" # On the first logged message, FancyLogger will prepend a help message # containing a list of all the severities (debug, info, warn, etc) styled # according to your config as reference. # You can disable this by setting the below option to false. show_help_message true # Under styles, you have a configuration for each severity. # Each severity has a configuration with the following valid options: # Key: foreground # Value: # :default, :black, :red, :green, :yellow, :blue, :magenta, :cyan, :white # # Key: background # Value: # :default, :black, :red, :green, :yellow, :blue, :magenta, :cyan, :white # # Key: reset # Value: true or false # # Key: bright # Value: true or false # # Key: italic # Value: true or false # # Key: underline # Value: true or false # # Key: # blink # Value: true or false # # Key: inverse # Value: true or false # # Key: hide # Value: true or false styles do debug do foreground :black background :cyan end info do foreground :default background :default end warn do foreground :yellow background :default blink true end error do foreground :red background :default end fatal do foreground :black background :red bold true underline true end unknown do foreground :black background :white underline true end end ``` ## Contributing * Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet * Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it * Fork the project * Start or switch to a testing/unstable/feature/bugfix branch * Commit and push until you are happy with your contribution * Make sure to add tests for it. This is important so I don't break it in a future version unintentionally. * Please try not to mess with the Rakefile, VERSION or gemspec. ## Copyright Copyright © 2012 Ryan Scott Lewis <ryan@rynet.us>.

# SshSig - SSH signature verification in pure ruby SshSig is a Ruby gem which can be used to verify signatures signed created by `ssh-keygen`. This capability was [first added](https://github.com/openssh/openssh-portable/commit/2a9c9f7272c1e8665155118fe6536bebdafb6166) in OpenSSH 8.0 allows SSH keys to be used for GPG-like signing capabilities, [including signing git commits](https://github.com/git/git/pull/1041). ## Installation Add this line to your application's Gemfile: ```ruby gem 'ssh_sig' ``` And then execute: $ bundle install Or install it yourself as: $ gem install ssh_sig ## Usage Version 1 of [the SSH signature format](https://github.com/openssh/openssh-portable/blob/b7ffbb17e37f59249c31f1ff59d6c5d80888f689/PROTOCOL.sshsig) supports `ed25519` and `rsa` keys. It is recommended that you use `ed25519` over `rsa` where possible (`ssh-keygen -t ed25519`). In order to verify a signature you need: 1. The public key of the sender 1. The signature file 1. The message to be verified. ```ruby require 'ssh_sig' armored_pubkey = "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAILXPkJPI4TMFWZP4xRBQjNeizUG99KuZCt9G23rX48kz" blob = ::SshSig::Blob.from_armor( <<~EOF -----BEGIN SSH SIGNATURE----- U1NIU0lHAAAAAQAAADMAAAALc3NoLWVkMjU1MTkAAAAgtc+Qk8jhMwVZk/jFEFCM16LNQb 30q5kK30bbetfjyTMAAAAEZmlsZQAAAAAAAAAGc2hhNTEyAAAAUwAAAAtzc2gtZWQyNTUx OQAAAECJITeYJIlEeydsCTh1DkfdhlDJFBa73ojfWe0MbrIzoJKd9THd9WeQrhygSRGsNG cU/stk3/919nykg67yG2gN -----END SSH SIGNATURE----- EOF ) message = "This message was definitely sent by Brian Williams" valid = ::SshSig::Verifier .from_armored_pubkey(armored_pubkey) .verify(blob, message) if valid puts 'Signature is valid' else puts 'Signature is not valid' end ``` Signatures can be created using `ssh-keygen -Y sign -n file -f ~/.ssh/ed_25519 message.txt` and will be outputted in `message.txt.sig`. Public keys can be found in a variety of places, including: - Your `~/.ssh/id_<alg>.pub` file - `authorized_keys` files on servers - `https://gitlab.com/<username>.keys` - `https://github.com/<username>.keys` The `SshSig::Verifier#from_gitlab` and `SshSig::Verifier#from_github` methods are provided to automatically load public keys from the respective `<username>.keys` urls. ```ruby require 'ssh_sig' blob = ::SshSig::Blob.from_armor( <<~EOF -----BEGIN SSH SIGNATURE----- U1NIU0lHAAAAAQAAADMAAAALc3NoLWVkMjU1MTkAAAAgtc+Qk8jhMwVZk/jFEFCM16LNQb 30q5kK30bbetfjyTMAAAAEZmlsZQAAAAAAAAAGc2hhNTEyAAAAUwAAAAtzc2gtZWQyNTUx OQAAAECJITeYJIlEeydsCTh1DkfdhlDJFBa73ojfWe0MbrIzoJKd9THd9WeQrhygSRGsNG cU/stk3/919nykg67yG2gN -----END SSH SIGNATURE----- EOF ) message = 'This message was definitely sent by Brian Williams' valid = ::SshSig::Verifier .from_gitlab('bwill') .verify(blob, message) if valid puts 'Signature is valid' else puts 'Signature is not valid' end ``` ## Is it safe to re-purpose SSH keys for signing? Yes. The [SSH signature protocol](https://github.com/openssh/openssh-portable/blob/d575cf44895104e0fcb0629920fb645207218129/PROTOCOL.sshsig) is designed to be resistant to cross-protocol attacks, where signatures created for one purpose (i.e. signing a git commit), may be re-used for another purpose (i.e. authenticating to a server). It does this using the magic pre-amble (to differentiate between messages signed by `ssh-keygen` and messages used for SSH authentication) and namespaces (to differentiate between messages signed by `ssh-keygen` but used for different purposes). This causes identical messages to produce different signatures for each different protocol. ## Development 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 the created tag, and push the `.gem` file to [rubygems.org](https://rubygems.org). ## Contributing Bug reports and pull requests are welcome on GitHub at https://github.com/[USERNAME]/ssh_sig. This project is intended to be a safe, welcoming space for collaboration, and contributors are expected to adhere to the [code of conduct](https://github.com/[USERNAME]/ssh_sig/blob/main/CODE_OF_CONDUCT.md). ## License The gem is available as open source under the terms of the [MIT License](https://opensource.org/licenses/MIT).
