Password hash retrieved from postgres table fails check on known password

Hello!

I've defined some user records:

(def fixtures
  {:accounts
   [{:email "admin@koi.com"
     :role "admin"
     :password (hashers/derive "secret")}
    {:email "modeller@koi.com"
     :role "modeller"
     :password (hashers/derive "secret")}
    {:email "user@koi.com"
     :role "user"
     :password (hashers/derive "secret")}]})

And created records for them in the DB:

              account_id              |         email         |                                              password                                              | account_role

However, when I try to (hashers/check "secret" (:password ..)) on any of the records, I get false back. This happens if I manually copy the password text into the check as well. Note that this only happens when I re-run the application. If I create a record, and check the hash in the same REPL session, then the check passes. I thought this may be due to the salt (I'm not specifying it, and therefore it's using the default (random-bytes 12)), but that's stored in the hash string, so that shouldn't be an issue.

Details: (1) algorithm: bcrypt+sha512 (I'm using defaults for both derive and check) (2) SQL type: varchar(98)

Have you encountered this in the past, or do you have an idea of what error I may be making on my end?
