Soledad写道： 这可能是值得的试图花一些时间试图找到一套有限的密码，这些密码被保证成为所有可能的生成器 MD5哈希（或者至少可能发生的哈希） ，这样你就可以在有限的时间内完成计算。 ------------------ ---------（广播结束）--------------------------- 提示7：别忘了增加你的免费空间地图设置 good day!is there a way to retrieve a user''s decrypted password, just like when iissued a "SELECT * FROM pg_shadow;" in the earlier version of postgresql?thanks in advance!ü*(ˉ`·.,??.·′ˉ`·.??.-> don v. soledad? 解决方案If you find a way to break MD5, a lot of people will be very veryinterested.regards, tom lane---------------------------(end of broadcast)---------------------------TIP 7: don''t forget to increase your free space map settingsSure, here''s the simple method:1: Generate a list of all possible passwords.2: Generate an md5 sig for each one.3: Compare your infinite number of md5 sigs to the one stored for theuser. When they match, you''ve got the original password, or at least apassword that will work just like the original.I think the total computer time required to do this is something on theorder of a few thousand years, so it might take a rather large farm ofmachines in a cluster to do this.---------------------------(end of broadcast)---------------------------TIP 9: the planner will ignore your desire to choose an index scan if yourjoining column''s datatypes do not matchIt is probably worth trying to spend some time trying to find a finiteset of passwords that are guarenteed to be generators for all possibleMD5 hashes (or at least those than can possibly occur), so that you canfinish the computation in finite time.---------------------------(end of broadcast)---------------------------TIP 7: don''t forget to increase your free space map settings 这篇关于解密的密码的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
