有史以来第一次，可免费下载的密码破解软件ocl-Hashcat-plus现在能破解最长55个字符的密码。Hashcat支持使用AMD或NVidia显卡同时破解大量加密哈希，它刚刚发布了v0.15，支持破解密码字符长度从15位增加到了55位。根据使用的破解技术和针对的哈希类型，软件支持最多64位字符和最少24位字符。流行的破解技术是暴力破解和字典搜索，而字典可以组合文学或维基百科条目中的短语增加成功率，例如一位研究人员成功破解了密码"Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn1"，这个虚构的神秘短语出自H.P. Lovecraft的短篇小说《克苏鲁的呼唤（The Call of Cthulhu）》，被包括在维基百科的"克苏鲁的呼唤"条目中。Hashcat的最新更新让普通用户拥有了原来只有密码破解者和安全研究人员才掌握的技术，能实现每秒猜测最多80亿个密码。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
