Java加密的几种方式

阅读更多关于 Java加密的几种方式

Java常用的加密方式 1.BASE64 严格来说BASE64不算是加密，而是对其编码格式进行修改，使之变为不易被人识别的形式。在实际使用中，将密码加密并储存到数据库中，登录时取出存储的密码，进行解密 /** * @author Myriven * @date 2019/12/23 14:23 * @description */ /*BASE564加密*/ public class BASE64Demo { public static void main ( String [ ] args ) throws IOException { String broforePWD = "password" ; System . out . println ( "加密前:" + broforePWD ) ; String afterPWD = encryptBASE64 ( broforePWD . getBytes ( ) ) ; System . out . println ( "加密后:" + afterPWD ) ; byte [ ] bytes = decryptBASE64 ( afterPWD ) ; System . out . println ( "解密后:" + new String ( bytes ) ) ; } /*加密*/ public static String

password_verify() returns false using password_compat library

问题 <?php $hash = password_hash("rasmuslerdorf", PASSWORD_DEFAULT); echo $hash; if (password_verify('rasmuslerdorf', $hash)) { echo 'Password is valid!'; } else { echo 'Invalid password.'; } ?> Above is my code on hashing password using bcrypt. Everytime I refresh my browser, the $hash returns different results, which I think it's normal because crypt() function does that too. However, I don't understand why the result returns 'Invalid Password' when comparing using password_verify() function. I

Java: Is this good use of BCrypt?

阅读更多关于 Java: Is this good use of BCrypt?

问题 I would like to know if my current implementation of BCrypt is correct, I am aware that I am not using BCrypt.checkpw() which may lead to an issue so that is the main reason I verify it here. Hasher.java container class: abstract public class Hasher { public static String hash(final char[] input) { String output = Hasher.hash(new String(input)); for (int i = 0; i < input.length; i++) { input[i] = 0; } return output; } public static String hash(final String input) { return BCrypt.hashpw(input,

问题 This question already has answers here : How to include third party Python libraries in Google App Engine? (6 answers) Closed 5 years ago . I have found a bcrypt library for python that seems to be very easy to use: bcrypt 1.0.1 After installing it and testing the hello world example in my local machine all seems fine: >>> import bcrypt >>> password = b"super secret password" >>> # Hash a password for the first time, with a certain number of rounds >>> hashed = bcrypt.hashpw(password, bcrypt

Configuring Spring Boot Security to use BCrypt password encoding in Grails 3.0

阅读更多关于 Configuring Spring Boot Security to use BCrypt password encoding in Grails 3.0

问题 In Grails 3.0, how do you specify that Spring Boot Security should use BCrypt for password encoding? The following lines should provide a sense of what I think needs to be done (but I'm mostly just guessing): import org.springframework.security.crypto.password.PasswordEncoder import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder PasswordEncoder passwordEncoder passwordEncoder(BCryptPasswordEncoder) My application loads spring-boot-starter-security as a dependency: build

save password as salted hash in mongodb in users collection using python/bcrypt

阅读更多关于 save password as salted hash in mongodb in users collection using python/bcrypt

问题 I want to generate a salted password hash and store it in MongoDB collection called users, like this: users_doc = { "username": "James", "password": "<salted_hash_password>" } I'm not sure how to generate the hashed password using Bcrypt, then when I login in my flask app, be able to check if the hash matches with the hashed password stored in MongoDB. 回答1: I don't know how you use mongodb to bring the data, but if you want to hash the pass it's as easy as: from flask import Flask from flask

Why can bcrypt.hashpw be used both for hashing and verifying passwords?

阅读更多关于 Why can bcrypt.hashpw be used both for hashing and verifying passwords?

问题 Using bcrypt with Python 2.7, I can see that the example uses the bcrypt.hashpw to both hash a password for storage and verify that the given password matches a hashed one, like so: Hashing import bcrypt password = b"somepassword" hashed = bcrypt.hashpw(password, bcrypt.gensalt()) Ok, so far so good. The given password is now hashed using bcrypt, so it is a string of hashed bytes. Verifying Now, here's the part that confuses me: to check that a plaintext password matches a hashed password,

How is bcrypt more future proof than increasing the number of SHA iterations?

阅读更多关于 How is bcrypt more future proof than increasing the number of SHA iterations?

问题 I've been researching bcrypt hashing, and of course one of the large benefits of the scheme its "adaptiveness". However, how is it anymore adaptive than simply increasing the amount of iterations you make over a SHA-1 hash? Say, instead of SHA-1 hashing a value 1000 times, you increase it to 10,000 iterations. Isn't this achieving the same goal? What makes bcrypt more adaptive? 回答1: Making many iterations with a hash function has a few subtleties, because there must be some kind of "salting"
