I don't use Dancer, but I believe what you're looking for is


The important things to do (especially if you opt not to use a plugin) is
to ensure you are using distinct per-user salts and using a strong hashing
algorithm (e.g. bcrypt).  You'll store the salt and the bcrypt result in
two columns in your DB.  To validate an authentication request from a user
you will take their input, concatenate it with the same salt, bcrypt the
result, and then compare the output to what you have stored.  If they
match, the password was correctly entered.
