WEBrick::HTTPAuth::Htpasswd

Htpasswd accesses apache-compatible password files. Passwords are matched to a realm where they are valid. For security, the path for a password database should be stored outside of the paths available to the HTTP server.

Htpasswd is intended for use with WEBrick::HTTPAuth::BasicAuth.

To create an Htpasswd database with a single user:

htpasswd = WEBrick::HTTPAuth::Htpasswd.new 'my_password_file'
htpasswd.set_passwd 'my realm', 'username', 'password'
htpasswd.flush

Public Class Methods

new(path) click to toggle source

Open a password database at path

 
               # File webrick/httpauth/htpasswd.rb, line 37
def initialize(path)
  @path = path
  @mtime = Time.at(0)
  @passwd = Hash.new
  @auth_type = BasicAuth
  open(@path,"a").close unless File::exist?(@path)
  reload
end

Public Instance Methods

delete_passwd(realm, user) click to toggle source

Removes a password from the database for user in realm.

 
               # File webrick/httpauth/htpasswd.rb, line 107
def delete_passwd(realm, user)
  @passwd.delete(user)
end

each() click to toggle source

Iterate passwords in the database.

 
               # File webrick/httpauth/htpasswd.rb, line 114
def each # :yields: [user, password]
  @passwd.keys.sort.each{|user|
    yield([user, @passwd[user]])
  }
end

flush(output=nil) click to toggle source

Flush the password database. If output is given the database will be written there instead of to the original path.

 
               # File webrick/httpauth/htpasswd.rb, line 76
def flush(output=nil)
  output ||= @path
  tmp = Tempfile.new("htpasswd", File::dirname(output))
  begin
    each{|item| tmp.puts(item.join(":")) }
    tmp.close
    File::rename(tmp.path, output)
  rescue
    tmp.close(true)
  end
end

get_passwd(realm, user, reload_db) click to toggle source

Retrieves a password from the database for user in realm. If reload_db is true the database will be reloaded first.

 
               # File webrick/httpauth/htpasswd.rb, line 92
def get_passwd(realm, user, reload_db)
  reload() if reload_db
  @passwd[user]
end

reload() click to toggle source

Reload passwords from the database

 
               # File webrick/httpauth/htpasswd.rb, line 49
def reload
  mtime = File::mtime(@path)
  if mtime > @mtime
    @passwd.clear
    open(@path){|io|
      while line = io.gets
        line.chomp!
        case line
        when %r!\A[^:]+:[a-zA-Z0-9./]{13}\z!
          user, pass = line.split(":")
        when /:\$/, /:{SHA}/
          raise NotImplementedError,
                'MD5, SHA1 .htpasswd file not supported'
        else
          raise StandardError, 'bad .htpasswd file'
        end
        @passwd[user] = pass
      end
    }
    @mtime = mtime
  end
end

set_passwd(realm, user, pass) click to toggle source

Sets a password in the database for user in realm to pass.

 
               # File webrick/httpauth/htpasswd.rb, line 100
def set_passwd(realm, user, pass)
  @passwd[user] = make_passwd(realm, user, pass)
end
