Clojurians Log v2

Hello, general question about crypto, if I want to use a secure hash function like bcrypt but I want the output to not be linkable to the input salt. I.e. not to check that a password is correct but to generate a key that can be used for lookup. Do I just use bcrypt and cut off the part of the output value that is the salt (feels hacky), or do I use some other hash algorithm? I would like to not use the SHA family since they seem to be less secure than bcrypt and other “slower” algorithms.

And Clojure related, what is the best way to use the chosen hash algorithm, I saw there were multiple implementations in Java of Bcrypt for example.
