The MD5 password hash algorithm is "no longer considered safe" by the original software developer, a day after the leak of more than 6.4 million hashed LinkedIn passwords.

Oracle says that starting with April 18, 2017, Java (JRE) will treat all JAR files signed with the MD5 algorithm as unsigned, meaning they'll be considered insecure and blocked from running.

A hash rate is the measure of the computational power in a proof-of-work cryptocurrency miner, pool, or network. High hash rates equal better odds of winning.
