We hesitated between BCrypt and PBKDF2 for password hashing. In many forums and blogs people say something like "In their Special Publication SP 800-132 NIST basically recommends using PBKDF2 for password hashing."
This may be a very important argument for our client (they adore standards). But I still cannot read this recommendation in plain text... So I can't claim it comfortably. In short NIST more or less say:
The derived keying material is called a Master Key (MK), denoted as mk. The MK is used either 1) to generate one or more Data Protection Keys (DPKs) to protect data, or 2) to generate an intermediate key to protect one or more existing DPKs or generated from the MK using an approved Key Derivation Function (KDF) as defined in . The MK shall not be used for other purposes.
Is there such a recommendation or this is just a myth?
