In light of passwords from LinkedIn and eHarmony being cracked and leaked, it has been announced that md5crypt is no longer considered safe (http://phk.freebsd.dk/sagas/md5crypt_eol.html).
I noticed that the Moodle docs say that Moodle uses md5 to encrypt user passwords: http://docs.moodle.org/19/en/Password_salting
Is there any recommended action to take?
