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
Open a password database at path
# File webrick/httpauth/htpasswd.rb, line 38 def initialize(path, password_hash: nil) @path = path @mtime = Time.at(0) @passwd = Hash.new @auth_type = BasicAuth @password_hash = password_hash case @password_hash when nil # begin # require "string/crypt" # rescue LoadError # warn("Unable to load string/crypt, proceeding with deprecated use of String#crypt, consider using password_hash: :bcrypt") # end @password_hash = :crypt when :crypt # require "string/crypt" when :bcrypt require "bcrypt" else raise ArgumentError, "only :crypt and :bcrypt are supported for password_hash keyword argument" end File.open(@path,"a").close unless File.exist?(@path) reload end
Removes a password from the database for user
in realm
.
# File webrick/httpauth/htpasswd.rb, line 144 def delete_passwd(realm, user) @passwd.delete(user) end
Iterate passwords in the database.
# File webrick/httpauth/htpasswd.rb, line 151 def each # :yields: [user, password] @passwd.keys.sort.each{|user| yield([user, @passwd[user]]) } end
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 103 def flush(output=nil) output ||= @path tmp = Tempfile.create("htpasswd", File::dirname(output)) renamed = false begin each{|item| tmp.puts(item.join(":")) } tmp.close File::rename(tmp.path, output) renamed = true ensure tmp.close File.unlink(tmp.path) if !renamed end end
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 122 def get_passwd(realm, user, reload_db) reload() if reload_db @passwd[user] end
Reload passwords from the database
# File webrick/httpauth/htpasswd.rb, line 68 def reload mtime = File::mtime(@path) if mtime > @mtime @passwd.clear File.open(@path){|io| while line = io.gets line.chomp! case line when %r!\A[^:]+:[a-zA-Z0-9./]{13}\z! if @password_hash == :bcrypt raise StandardError, ".htpasswd file contains crypt password, only bcrypt passwords supported" end user, pass = line.split(":") when %r!\A[^:]+:\$2[aby]\$\d{2}\$.{53}\z! if @password_hash == :crypt raise StandardError, ".htpasswd file contains bcrypt password, only crypt passwords supported" end 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
Sets a password in the database for user
in realm
to pass
.
# File webrick/httpauth/htpasswd.rb, line 130 def set_passwd(realm, user, pass) if @password_hash == :bcrypt # Cost of 5 to match Apache default, and because the # bcrypt default of 10 will introduce significant delays # for every request. @passwd[user] = BCrypt::Password.create(pass, :cost=>5) else @passwd[user] = make_passwd(realm, user, pass) end end
