passwords

问题 I'm trying to replicate the Java code in JavaScript. below is my Java code: public static String encrypt(String input) final byte[] SALT= { (byte) 0x21, (byte) 0x21, (byte) 0xF0, (byte) 0x55, (byte) 0xC3, (byte) 0x9F, (byte) 0x5A, (byte) 0x75 }; final int ITERATION_COUNT = 31; { if (input == null) { throw new IllegalArgumentException(); } try { KeySpec keySpec = new PBEKeySpec(null, SALT, ITERATION_COUNT); AlgorithmParameterSpec paramSpec = new PBEParameterSpec(SALT, ITERATION_COUNT);

问题 I am new to web development. Am I allowed to store users' original passwords? I know good practice is to store the hashed password using a salt, but why don't we store the original password? Is it because the database is easily hacked, so hashing protects passwords? Are there any other reasons? If not, I would like to store the original password if it is legal to do so. 回答1: The legality depends on the country you live in. But there are best practices, too. And a best practice is to encrypt

问题 In a sentence, I want to configure JBoss 4.2.2 to use DatabaseServerLoginModule as the login-module for a Web application that is secured via Digest Authentication. The problem I am having is that the passwords fail to validate. I suspect the issue is either in how I've defined the application policy or in how the passwords are stored in the database. Below are all the relevant files. I have a MySQL database with users and roles defined using the following schema: CREATE TABLE SR_USER ( ID

问题 I have a list of passwords that I need to examine and determine if they meet the default 3 of 4 rule for AD. Rule is contain 3 of the 4 following requirements: lower case character (a-z) upper case character (A-Z) numeric (0-9) special character ( !@#$%^&*()_+= ) I am still learning Regex. I know how to select only those that meet any one character case, but I am not sure how to do 3 of 4. As a side note, the AD Complexity has two more subtleties that are important (but out of scope of the

问题 I have the following PowerShell script that creates a random string of 15 digits, for use as an Active Directory password. The trouble is, this works great most of the time, but on some occasions it doesn't use a number or symbol. I just get 15 letters. This is then not usable as an Active Directory password, as it must have at least one number or symbol in it. $punc = 46..46 $digits = 48..57 $letters = 65..90 + 97..122 $YouShallNotPass = get-random -count 15 ` -input ($punc + $digits +

问题 This is regarding the Java String Constant Pool. In one of my Programs i am decrypting the password for the database and storing it in a String. I heard that the Java Strings will be stored in a Constant pool and they won't be destroyed the VM restarts or the ClassLoader that loaded the String Quits. If it is the case my passwords will be stored in the String pool. I am Very concerned about this issue. Is there any other way to destroy these literals or anything else i can do. Please suggest

问题 I have a C# application that needs to connect to an SQL database to send some data from time to time. How can I safely store the username and password used for this job? 回答1: There is a nice MSDN article about how to secure connection strings in .Net. You might want to use protected configuration. 回答2: Use integrated Windows authentication whenever possible. It takes the onus off of your application and lets Windows handle it. Using Windows authentication instead of SQL authentication is

问题 This question already has answers here : Closed 6 years ago . Possible Duplicate: What algorithm should I use to hash passwords into my database? I am new to this hashing on password. I read the hashing + salt make passwords really safe. But still confused which hashing algorithm should I use as there are many like. MD5CryptoServiceProvider SHA1Managed SHA256Managed etc. How can I decide which one is good for me or all are equal. Can I pick up anyone blindly? 回答1: MD5: In 1996, a flaw was
