Generating and verifying password hashes with flask-bcrypt

由 断了今生、忘了曾经 提交于 2019-12-07 14:35:28
问题 So I've recently learned how to store passwords in a DB, that is by adding a salt to the plaintext password, hashing it, and then storing the hash. I'm working on a really small Flask app to try all this out, but I'm having a problem with the password hashing and checking parts of the process. It seems that I"m ending up with two different hashes for the same input and I can't seem to figure out why. I ran a little experiment in the interpreter to test things out. >>> from os import urandom >

How to check Cookie Token against bcrypt-hashed Token in DB when using Persistent Login Cookies?

由 烂漫一生 提交于 2019-12-07 05:08:08
问题 In this popular solution for Persistent Login Cookies which involves generating a random 128-bit "token" to be saved in the user's Cookie, Jens Roland recommends: And DO NOT STORE THE PERSISTENT LOGIN COOKIE (TOKEN) IN YOUR DATABASE, ONLY A HASH OF IT! The login token is Password Equivalent, so if an attacker got his hands on your database, he/she could use the tokens to log in to any account, just as if they were cleartext login-password combinations. Therefore, use strong salted hashing

Variable and degrading performance when using jbcrypt

由 放肆的年华 提交于 2019-12-07 02:05:59
问题 I'm using jbcrypt to hash passwords in a project. Performance is about 500 ms when validating passwords on the hardware I am using (log_rounds set to 12). However, after a while with regular use the performance time suddenly drops to a whopping 15 seconds. The drop is very sudden with no buildup and stays constant until the process is restarted. Profiling shows that the extra time is used in the key(..) method. Source: http://jbcrypt.googlecode.com/svn/tags/jbcrypt-0.3m/src/main/java/org

Is Bcrypt used for Hashing or Encryption? A bit of confusion

由 ￡可爱￡侵袭症＋ 提交于 2019-12-06 16:58:51
问题 I have been reading about bcrypt (application perspective). Thinking of using it to store passwords on my site. Out of some stuff that I read it suggests either ways: e.g. 1: Bcrypt is a cross platform file encryption utility from bcrypt e.g. 2: bcrypt is an adaptive password hashing algorithm which uses the Blowfish keying schedule, not a symmetric encryption algorithm. from How To Safely Store A Password bcrypt is an adaptive cryptographic hash function for passwords designed by Niels

Using BCrypt password hashing with Spring Security Grails plugin

由 和自甴很熟 提交于 2019-12-06 10:32:53
问题 I'm trying to use the BCrypt password hashing in my Grails app that's using the Spring Security plugin. I've enabled BCrypt by adding the following to Config.groovy grails.plugins.springsecurity.password.algorithm = 'bcrypt' And I've defined the following codec to simplify using BCrypt to encode paswords: public class PasswordCodec { // it doesn't seem to be possible to dependency-inject codecs, so lookup the bean ourselves @Lazy private static PasswordEncoder passwordEncoder = Holders

Safely Storing sensitive data client side

Back Story I work at a small-mid size company and we are reworking our customer facing accounting portal and my manager wants to make single click payment option with the Credit Card info stored in cookies on the end users computer. I'm not in love this the idea.... at all (in fact I'm still trying to change his mind). That being said I am trying to make it as secure as I can, I think I've got a way to minimize the risk, here it is: using SSL for all exchanges encrypt the data in a number of cookies that are stored locally having the cipher as a confirm password that must be entered each time.
