Takeshi: Do you still think that it's dubious to have password-based encryption algorithms in the specification? Everybody may wish to take note that PKCS#5 is currently being modified to include AES, RC6, SHA256, SHA384, and SHA512, but that the official standard does not yet include those algorithms.
