úÎ-x     0Encapsulates the three tuning parameters to the  function: N,  r and p (see above).  Constructor function for the  data type log_2(N). Scrypt's N* parameter must be a power of two greater  than one, thus it'3s logarithm to base two must be greater than zero.  128*r*N: must be smaller than the available memory address space. The parameter r, must be greater than zero. The parameter p, must be greater than zero. r and p  must satisfy r*p < 2^30. Returns + the parameter object for valid arguments,  otherwise . 7Default parameters as recommended in the scrypt paper:   N = 2^14, r = 8, p = 1 Equivalent to  (  14 8 1). JEncrypt the password with the given parameters and a random 32-byte salt.  The salt is read from /dev/urandom. Equivalent to encryptPass defaultParams.  Verify a   against an . The function also takes  9 meeting your current security requirements. In case the  7 was generated with different parameters, the function  returns an updated , generated with the given  . The  is kept from the given . #Parameters to use for updating the . The candidate  . The  to check against. Returns a pair of   - indicating verification success or failure.   a new  if the given  are / different from those encapsulated in the given ,  otherwise . Equivalent to verifyPass defaultParams. HCalculates a 64-byte hash from the given password, salt and parameters. Note the prime symbol (' ).
