WebNice tutorial, but why do you think encrypt() is any way better than hmac()? At a glance it's much worse: 1) it's (needlessly, after bcrypt) slower; 2) when attacker know pepper he can just decrypt() to get bcrypt's result and then bruteforce using just bcrypt, while with HMAC he will need to do bruteforce using hmac+bcrypt which complicate things a little for him; 3) … WebMar 14, 2024 · Verify the SPN you need is on the Active Directory account: setspn -L MyappEU.
