These iteration counts were considered appropriate a decade ago. <a href="http://security.stackexchange.com/questions/3959/recommended-of-iterations-when-using-pkbdf2-sha256">http://security.stackexchange.com/questions/3959/recommended-of-iterations-when-using-pkbdf2-sha256</a> We get similar numbers on SandyBridge-E desktop and Haswell i7-4600U laptop: * with 10k iterations ~20 msec per derivation * with 100k iterations ~195 msec per derivation * with 150k iterations ~290 msec per derivation We can't go too high though because in ODF every package stream gets its own derived key with a different salt, so a document with embedded images may need a lot of these.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
