sha256

I'm looking for a hash implementation that is; secure (practically impossible to invert) fast (few ms) light (few KB) runs in the browser Ideally a SHA-256 implementation, since it is widely used and therefore widely tested against. Doing some tests suggests that forge is the fastest SHA-256 JavaScript implementation. It is 284KB big but extracting the SHA-256 related code reduces the size to 4.5 KB, see https://github.com/brillout/forge-sha256 . 来源： https://stackoverflow.com/questions/31219009/fast-and-light-javascript-sha-256-secure-hash-implementation

I have encountered a blocker with the .NET Framework version 4.5 to do with signing of XML with digital signatures. My problem is based around the need to sign individual XML elements with X.509 certificate with the RSA SHA-256 algorithm. I have read many .NET posts on this topic and it appears that there is a solution originally developed in the CLR Security project RSAPKCS1SHA256SignatureDescription.cs class. RSAPKCS1SHA256SignatureDescription has of course since been incorporated into the .net runtime and as of .NET 4.5 is now available under the distributed binary System.Deployment.dll. I

I need to generate a SHA256 base 64 hash from a table in SQL server but I can't find that algorithm in the list HASHBYTES arguments. Is there a way to generate it directly in SQL Server? Duplicate disclamer: My question is not duplicate of SHA256 in T-sql stored procedure as I am looking for the SHA256 base 64 version of the algorithm which is not listed in the page. Numeric Example I have this query result in SQL Server Start date,End date,POD,Amount,Currency 2016-01-01,2016-12-31,1234567890,12000,EUR this give me the following string (using concatenate function) 2016-01-012016-12

in the specification of the "DFÜ agreement" is described to calculate the hashvalue for a SEPA container payment file by SHA256. The hash value is created using the entire contained document, including the opening and closing "document" tag. The document is canonised according to Canonical XML, version 1.0. ( http://www.w3.org/TR/2001/REC-xml-c14n-20010315 ). In the case of included documents, the canonisation has also to be executed according to the main document. SHA-256 is used as hash algorithm. The hash value is entered in hexadecimal form in the tag, capital characters are used for the

I have a simple question. I need to rewrite a sha256 checksum method from java to C# So I have this Java cod to work with : Canonicalizer c14Canonicalizer = Canonicalizer.getInstance(Canonicalizer.ALGO_ID_C14N_EXCL_WITH_COMMENTS); byte[] byteArray = c14Canonicalizer.canonicalizeSubtree(doc); // At this point, the byteArray in Java and the data in C# matches up. // That is, after the java bytes are converted to unsigned bytes using // java.lang.Byte.toUnsignedInt() MessageDigest md = MessageDigest.getInstance("SHA-256"); md.update(byteArray); byte byteData[] = md.digest(); (byteArray is, you

I have a java code base that generates an URL safe base64 encoded hash from a string, and wondering if / how this would be possible with linux command line tools. I'm guessing the problem with what I am doing here is with the character set / encoding or to do with converting the string to a byte array. Java code: MessageDigest md = MessageDigest.getInstance("SHA-256"); byte[] digest = md.digest("testString".getBytes()); // ^^ this is where the difference is? String b64url = Base64.encodeBase64URLSafeString(digest); // b64url: Ss8LOdnEdmcJo2ifVTrAGrVQVF_6RUTfwLLOqC-6AqM Command line: echo

一、简单介绍 　　前面已经介绍，可以使用Docker Hub公共仓库，但是大多数情况企业都需要创建一个本地仓库供自己使用。这里介绍几种搭建私库的方法 　　私库的好处有几点 　　　　1、节约带宽 　　　　2、可以自己定制系统 　　　　3、更加安全 二、我知道的几种方法 　　1、利用官方提供的工具docker-registry来配置私库 　　　　官方提供的镜像，注意这个工具是个镜像，直接下载并使用registry镜像启动docker实例就可以了 　　2、利用Harbor-Registry，来搭建私库 　　　　Harbor是一个用于存储Docker镜像的企业级Registry服务 　　　　 三、通过官方docker-registry来配置私库 　　1、环境 　　　　docker私库地址：192.168.216.51 web1 　　　　docker服务器地址：192.168.216.52 web2，此节点使用私库服务器来pull/push镜像 　　2、拓扑 　　　　 　　　　备注：这里docker hub 就是私库 　　　　　　　docker engine ：前面原理篇有介绍 ，是docker架构中的运行引擎，同时也Docker运行的核心模块。它扮演Docker container存储仓库的角色，并且通过执行job的方式来操纵管理这些容器。 　　3、安装docker私有仓库 　　　　1
