Now that Scrypt has been used by cryptocurrency a new generation of
hardware optimized miner (that can be converted to password-cracking)
went out https://www.hashcoins.com/buy-scrypt-miners/ .
The questions are:
a) Is scrypt always safe enough?
b) Which scrypt parameters should be tweaked in order to make it *much
more* difficult to the hardware minire?
c) Is the approach of chaining multiple hashing systems (to require the
attacker to implement multiple hardware-specialized system) valuable
like done by some crypto-currency?
The assumption is that if i need to buy 10 different specialized-ASIC to
attack a specific crypto, it's obviously going to cost more.
