# Rack::Auth::Digest::Nonce

Rack::Auth::Digest::Nonce is the default nonce generator for the Rack::Auth::Digest::MD5 authentication handler.

`private_key` needs to set to a constant string.

`time_limit` can be optionally set to an integer (number of seconds), to limit the validity of the generated nonces.

### Attributes

private_key[RW]
time_limit[RW]
