Spring Security 3 + Random Salt

由 孤街浪徒 提交于 2019-12-10 11:34:19
问题 So I understand that you can check a password in Spring Security with salt based on a userDetail property and then hash it to compare to a hash in the database, however what if the salt used when creating each user is random (and is stored in the DB), would I need to create my own userDetails class that contains a salt property and then set that as the field spring security uses to salt with in the securityApplicationContext? If so how would I go about writing my own userDetails class to

问题 I'm running a web service on Django. Users register to my system and provide me login details (username and password) for a 3rd party web service). My purpose is to store this details in the best and safest way. Unfortunately my service needs this data for some offline scripts that query the 3rd party service, so I cannot store the login/password encrypted with user password (and use it to a key do decipher them. I read lots of articles on stackoverflow, but most of them (like: What is the

问题 Fundamental difference between Hashing and Encryption algorithms Preferred Method of Storing Passwords In Database http://codahale.com/how-to-safely-store-a-password/ I am confused about two things. If PHP 7.0 bcrypt provides a randomized salt. How are we supposed to retrieve it for password verification? I understand there key stretching functions like PBKDF2 but can someone explain to me why a memory intensive hashing algorithm like scrypt is preferred over something like bcrypt? Besides

Multiple Encryption Technique in Java

由 半世苍凉 提交于 2019-12-08 22:41:34
Is it safe to encrypt an already encrypted data using another algorithm? For instance, I have encrypted a password using "PBKDF2WithHmacSHA1". Now I want to further encrypt it using "SHA512" (since it is considered better than "SHA1") Will that in any way weaken my encryption? Also, should I reverse the encrypted password to increase security? Even if "PBKDF2WithHmacSHA1" is enough, I would rather have extra layers of protection. That is why I have been thinking of multiple encryption. However, I am not intending to use third-party options such as BouncyCastle at present. It would be helpful

How to create a PBKDF2-SHA256 password hash in C# / Bouncy Castle

由 北慕城南 提交于 2019-12-07 00:10:49
问题 I need to create a PBKDF2-SHA256 password hash, but am having some trouble. I downloaded the Bouncy Castle repo, but got a bit stuck finding what I was looking for in the Unit Tests. Found some sample code here, but this only does SHA1. The key bit of code is: /// <summary> /// Computes the PBKDF2-SHA1 hash of a password. /// </summary> /// <param name="password">The password to hash.</param> /// <param name="salt">The salt.</param> /// <param name="iterations">The PBKDF2 iteration count.<
