877 %For instance, SHA512crypt, which is included in Mac OS X and most Unix-based operating systems, passes text through 5,000 iterations, a %hurdle that would have limited Gosney to slightly less than 2,600 guesses per second. The Bcrypt algorithm is even more computationally %expensive, in large part because it subjects text to multiple iterations of the Blowfish cipher that was deliberately modified to increase the %time required to generate a hash. PBKDF2, a function built into Microsoft's .Net software developer framework, offers similar benefits. |
