hash

问题 Is there a way to sign the hash of an xml file and then integrate this signed hash into the original file. For the PDF signature I use iText and it works very well. UPDATE 1 : Sign Original XML FILE public class SignXML { static String fileToSign = "B:/tmp/client/032936.xml"; static String signedFile = "B:/tmp/client/Signed-032936.xml"; static String certificate = "C:/lp7command/tools/certificate.p12"; static String password = "123456"; public static void main(String[] args) throws Exception{

问题 Angular production build is not generating unique hashes in my project. Below are the build logs screenshot Not able to reproduce this issue in new angular cli project, seems there is some issue in my project. I am using angular - 6.0.3 Below is the angular.json { "$schema": "./node_modules/@angular/cli/lib/config/schema.json", "version": 1, "newProjectRoot": "projects", "projects": { "exampleProject": { "root": "", "sourceRoot": "src", "projectType": "application", "prefix": "app",

问题 I have been through the Identity Server 4 QuickStart for using Entity Framework for persistent storage of configuration and operational data. In the QuickStart, the ApiResources are loaded into the database in code. The Api secret is set with new ApiResource("api1", "My API") { ApiSecrets = { new Secret("secret".Sha256())} } in the ApiResource constructor. When, in Startup.InitializeDatabase, that ApiResource is added to the ConfigurationDbContext.ApiResources DbSet, foreach(var resource in

问题 I currently have been given the following java code snippet as an example of how to calculate a hash based on a supplied 'in' and 'salt' variable. In these examples the variables are hardcoded for testing: package generatehash; import java.security.MessageDigest; import sun.misc.BASE64Encoder; public class GenerateHash { public static void main(String[] args) { String in = "abcdef12345"; String salt = "test1"; try { MessageDigest hash = MessageDigest.getInstance("SHA-256"); byte[] digest =

问题 We've to decrypt a ciphertext encrypted using RSA OAEP and we're trying to use RsaCng. The ciphertext was produced using Java, and the Java API allows you to specify a different hash function for the label and for the mask generation function (MGF1). In this specific case, SHA-256 was used in the first case and SHA-1 in the second (yes, not a good idea but we have no control over this). Now, from what I understand using RsaCng I can only specify one hash function (using RSAEncryptionPadding

问题 I have a multi-dimensional hash in perl and I would like to change the first key for a chosen value. For example, I have the hash my %Hash1; $Hash1{1}{12}=1; $Hash1{1}{10}=1; $Hash1{2}{31}=1; $Hash1{3}{52}=1; $Hash1{3}{58}=1; $Hash1{4}{82}=1; $Hash1{4}{154}=1; Now I want to replace the value 3 in the first key with the value 300. After this I would get: $Hash1{1}{12}=1; $Hash1{1}{10}=1; $Hash1{2}{31}=1; $Hash1{300}{52}=1; $Hash1{300}{58}=1; $Hash1{4}{82}=1; $Hash1{4}{154}=1; I know I could

问题 I have a website that uses javascript that uses angular to control what you see on the website. So http://somewebsite.com/#page1 is shown and when you click on a tab that location changes to http://somewebsite.com/#page2. There will be no actual reload on the website and therefor func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) will not get triggered. How can you catch these hash changes? Clearly Apple can, since the Safari webbrowser is able to show these changes in

问题 I know the difference between Hashtable and HashMap. However, both these classes seemingly are using a hash function to get the job done. Is there a difference between the hash function used in Hashtable, and the hash function used in HashMap? In particular, is there a difference between the hashing algorithm they use? What is the formula used to hash in these two classes? In other words, is the way for calculating index (hash value) different? 回答1: In particular, is there a difference
