class RbNaCl::PasswordHash::Argon2

def initialize(opslimit, memlimit, digest_size = nil)

Returns:
  • (RbNaCl::PasswordHash::Argon2) - An Argon2 password hasher object

Parameters:
  • digest_size (Integer) -- the byte length of the resulting digest
  • memlimit (Integer) -- the memory cost (e.g. 2**24)
  • opslimit (Integer) -- the CPU cost (1..10)
