Description

Crypt::PBKDF2 versions before 0.261630 for Perl have a weak default algorithm and number of iterations. The default algorithm is HMAC-SHA1, which should only be used for legacy systems. These versions default to using 1000 iterations. Depending on the chosen algorithm, 220,000 to 1,400,000 iterations should be used.
