When strength is used with key-derivation functions that support an
arbitrary number of iterations (such as PBKDF2), values of
strength >= 64 will be taken as an iteration count, while existing
behavior is retained for strength values in the range [1, 31].
Added support for non-password-based symmetric keys provided as raw
key material, either via a byte[] or a pair SecretKeySpec objects
(one for cipher and one for MAC).
Added new HMAC-SHA1 algs:

  BCRYPT_AES256_HMAC_SHA1
  PBKDF2_SHA1_AES256_HMAC_SHA1
  PBKDF2_SHA512_AES256_HMAC_SHA1
  SCRYPT_AES256_HMAC_SHA1
