bcrypt

问题 How is bcrypt stronger than, say, def md5lots(password, salt, rounds): if (rounds < 1) return password else newpass = md5(password + salt) return md5lots(newpass, salt, rounds-1) I get the feeling, given its hype, that more intelligent people than me have figured out that bcrypt is better than this. Could someone explain the difference in 'smart layman' terms? 回答1: There are three significant differences between bcrypt and hashing multiple times with MD5: The size of the output: 128-bit (16

问题 OK, I finally understand bcrypt, how it works, and how to store it in the DB, so I'm almost good to go. The problem now is picking which implementation of bcrypt to use with PHP 5.3 . I'm going crazy looking at all the different solutions, and I'm not sure which one is the most recommended and safest to use, so I'm once again turning to you guys. Here are the ones I've found: 1) https://gist.github.com/marcoarment/1053158 2) http://www.openwall.com/phpass/ 3) https://stackoverflow.com/a

问题 I have the following snippet of code: // bcrypt hash of 'password' $hash = '$2y$10$4u0cQ.WEnwHDo.C5Nl1vm.shKA0beQ32wqzphSfzklAq9OcDM2nLu'; if(password_verify('password', $hash)) { print_r('woohoo!'); } else { print_r('fubar'); } On one server it's working fine (woohoo!), on another it doesn't work. I've just put it up on codepad.org and it fails there too. The problem is (as can be see on that codepad page) that the hash computed by crypt is of length 13 instead of the required 60. I'm using

问题 In order to do some image processing using the Node library, Sharp, I had to upgrade my node executable on Azure App Service to 64-bits. I did this by downloading the executable manually and then setting its path in IISNode.yml . Unfortunately, when I start the app, it throws the following error: Application has thrown an uncaught exception and is terminated: Error: %1 is not a valid Win32 application. \\?\D:\home\site\wwwroot\node_modules\bcrypt\build\Release\bcrypt_lib.node at Error (native

问题 I'm currently trying to make authentication module for my project in node.js? I've already seen some examples of using bcrypt to generate hashes, i.e. https://github.com/bnoguchi/mongoose-auth/blob/master/lib/modules/password/plugin.js https://github.com/Turbo87/locomotive-passport-boilerplate/blob/master/app/models/account.js However, for some reason they are using bcrypt.hashSync() function. Since bcrypt is good because it's time-consuming, wouldn't it be wiser to use asynchronous function

问题 What is the difference between PASSWORD_DEFAULT and PASSWORD_BCRYPT? Do they both use Blowfish encryption algorithm? What is cost in an algorithm? How to set up password_hash in PHP produce a 255-hash length instead of 60? 回答1: Currently PASSWORD_BCRYPT is the only algorithm supported (using CRYPT_BLWFISH), therefore there is currently no difference between PASSWORD_DEFAULT and PASSWORD_BCRYPT . The purpose of PASSWORD_DEFAULT is to allow for the inclusion of additional algorithms in the

问题 I'm trying to store salt and hashed password before inserting each document into a collection. But on encoding the salt and password, it shows the following error: line 26, in before_insert document['salt'] = bcrypt.gensalt().encode('utf-8') AttributeError: 'bytes' object has no attribute 'encode' This is my code: def before_insert(documents): for document in documents: document['salt'] = bcrypt.gensalt().encode('utf-8') password = document['password'].encode('utf-8') document['password'] =
