After consideration, the basic authentication implementation has been simplified to only support bcrypt entries in an htpasswd file. This greatly increases the security of the implementation by reducing the possibility of timing attacks and other problems trying to detect the password hash type. Also, the htpasswd file is only parsed at startup, ensuring that the file can be edited and not effect ongoing requests. Newly added passwords take effect on restart. Subsequently, password hash entries are now stored in a map. Test cases have been modified accordingly. Signed-off-by: Stephen J Day <stephen.day@docker.com>
