password-encryption

问题 I am working with Django users, and I've hashed the passwords when I create an user with Django REST Framework and I override the create and update methods on my serializer to hash my passwords users class UserSerializer(serializers.ModelSerializer): #username = models.CharField() def create(self, validated_data): password = validated_data.pop('password', None) instance = self.Meta.model(**validated_data) if password is not None: instance.set_password(password) instance.save() return instance

问题 I have developed a small project on Spring MVC. The project has account table and account has an encoded password with BCryptPasswordEncoder. I have used java config instead of XML config. @Configuration @EnableWebSecurity public class SecurityConfiguration extends WebSecurityConfigurerAdapter @Bean public PasswordEncoder passwordEncoder() { return new BCryptPasswordEncoder(); } } I get user information and encode the password. @Autowired private PasswordEncoder passwordEncoder; String pass

问题 Due to security requirements I need to store the Database password as a md5-hash in my hibernate.cfg.xml, but as far as I know Hibernate does not support hashed passwords. I am using hibernate 5.1.0. My hibernate.cfg.xml looks like this: <?xml version='1.0' encoding='UTF-8'?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name=

问题 I am new to the encryption process and have tried unsuccessfully to install an encrypted web.config file onto a hosting companies server. I am using Microsoft Visual Web Developer 2010 Express. I have followed the steps located in Walkthrough: Encrypting Configuration Information Using Protected several times. Please Note regarding the walkthrough, I do not have any machineKeys in my web.config file, so I skipped that encryption step. When I Ran the aspnet_regiis -pef connectionStrings "c:

问题 All the examples online show the use of crypt like this: $pass = crypt('something','$6$rounds=5000$anexamplestringforsalt$'); But everyone says that you are not supposed to define the rounds or the salt. So how should I use it? Also I am having a problem: when I run the code above, it only runs 50 rounds instead of 5000 rounds as if the system is stopping it. Any help will be greatly appreciated. //- Solution -// I have found some of these to be useful: For generating Salt: $salt = substr(str

问题 I am a beginner so if this question sounds stupid, please bear with me. I am wondering that when we write code for username/password check in python, if it is not compiled to exe ie script state , won't people will easily open the file and remove the code potion that is doing the password check? I am assuming that the whole program is entirely written in python , no C or C++ . Even if I use a program like py2exe it can be easily decompiled back to source code. So, does that mean it is useless

问题 I am using password_hash for password encryption. However there is a strange question, password_hash cost very long time. Here is a sample code. this code will cost more than 1 second. Is that normal? <?php $startTime = microtime(TRUE); $password='123456'; $cost=13; $hash=password_hash($password, PASSWORD_DEFAULT, ['cost' => $cost]); password_verify($password,$hash); $endTime = microtime(TRUE); $time = $endTime - $startTime; echo $time; ?> the result is :1.0858609676361 回答1: After running on

问题 I am writing a simple app to encrypt my message using AES / CBC (mode). As my understanding CBC mode requires IV parameter but I don't know why my code work without IV parameter used. Anyone can explain why? Thanks. The encrypted message printed: T9KdWxVZ5xStaisXn6llfg== without exception. public class TestAES { public static void main(String[] args) { try { byte[] salt = new byte[8]; new SecureRandom().nextBytes(salt); SecretKeyFactory keyFactory = SecretKeyFactory.getInstance(

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.
