> SHA2 + salt + pepper is sufficient Not even close. The attempts/sec you can run against SHA-2 vs. the attempts/sec you can run against bcrypt or scrypt are an order of magnitude apart. You should not use anything less than a proven KDF (scrypt, bcrypt, PBKDF2-HMAC-SHA2 with a lot of rounds) for password storage. Many of your posts conflate "cryptographic" with "password hashing", which is certainly not the case. Note that PBKDF2-HMAC-SHA2 does not (at all) mean that SHA-2 is useful for password hashing. As someone else pointed out, that's just an implementation detail.
