In cryptography, a pepper is a secret added to an input such as a password during hashing with a cryptographic hash function. This value differs from a salt in that it is not stored alongside a password hash, but rather the pepper is kept separate in some other medium, such as a Hardware Security Module. Note that the … See more The idea of a site- or service-specific salt (in addition to a per-user salt) has a long history, with Steven M. Bellovin proposing a local parameter in a Bugtraq post in 1995. In 1996 Udi Manber also described the advantages of such … See more In the case of a pepper which is unique to each user, the tradeoff is gaining extra security at the cost of storing more information … See more • Salt (cryptography) • HMAC • passwd See more There are multiple different types of pepper: • A secret unique to each user. • A shared secret that is … See more In the case of a shared-secret pepper, a single compromised password (via password reuse or other attack) along with a user's salt can lead to an attack to discover the pepper, … See more WebAt 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) with wrong encryption algo or mode (CBC/EBC) it may ...
