I'm using a different bcrypt module, Crypt::Eksblowfish::Bcrypt,

According to the documentation, [mod://Digest::Bcrypt] is mostly a wrapper around [mod://Crypt::Eksblowfish::Bcrypt].

.. it stores both the settings and the salt in the output hash

Does that mean you can deduce the <i>cost</i> from the output hash alone? In order to adjust the cost over time, one either need to store the cost or be able to compute it (e.g. from the output hash).
