This question already has an answer here: Is it useless to sign my Windows application with a self signed certificate? 2 answers I have a installer file created with Inno Setup of an application that I developed. So when I go to install the program, it shows me a window telling me that my application is not trusted. How can I sign my installer file to avoid that window when a user installs my program, or to make my installer a trusted installer? I have a .pfx file that I generated with OpenSSL and my SSL certificate. I tried signing it with the Inno Setup signing tool but without success. This

I am using iText 5.5.5 for Java and I would like to create signed PDF with external signature as follows: Take the PDF document that should be signed and create PDF with empty signature and provide BASE64 encoded bytes to be signed by external signature mechanism: PdfReader reader = new PdfReader(src); FileOutputStream os = new FileOutputStream(dest); PdfStamper stamper = PdfStamper.createSignature(reader, os, '\0'); PdfSignatureAppearance appearance = stamper.getSignatureAppearance(); appearance.setVisibleSignature(new Rectangle(36, 748, 144, 780), 1, "test"); appearance.setCertificate(chain

I need to sign a XML document using a PKCS12 certificate (.p12 file) in PHP, the standard must be XADES-BES. Is this possible? hakre It is most likely possible but equally likely has never been done with PHP code yet. XML validation with XMLDSIG using XadES-BES algorithm Existing PHP XML Digital Signature libraries for example are: xmlseclibs FraGoTe/xmldsig Maks3w/xmldsig It's probably a good bet to built on top of xmlseclibs . 来源： https://stackoverflow.com/questions/29173278/sign-xml-document-xades-bes-with-pkcs12-certificate-p12-in-php

目录 某住会sign与data算法 抓包分析 反编译 寻找data、sign处理逻辑 逆向libhzsign.so 还原算法 验证算法正确性 @(某住会sign与data算法) 某住会sign与data算法 经抓包分析得知，华住会app请求参数中有三个，分别是sign、data、time。time一眼可看出，就是当前时间，精确到秒。sign与data是经过一系列运算后 base64编码。 抓包分析 从图中可以看到，请求和响应均不是明文，响应报文从响应头中的content-type application/octet-stream 可以看到是字节流的形式，切换到十六进制模式。 反编译 这里我们用jeb打开，并导出源码，用idea打开 寻找data、sign处理逻辑 经过搜索和分析得知，计算data的代码在 public class NewGetString { static { System.loadLibrary("hzsign"); } public static String a(String arg2, String arg3) { Class v0 = NewGetString.class; __monitor_enter(v0); try { arg2 = NewGetString.getNewStr(arg2, arg3).replaceAll("\r\n", "");

I have a string.Format like this : string Test = string.Format("{0:#,0}", NegativeNumber); how can I change the negative sign position (Direction -> left or right)? James Manning The easiest route might be to just have a different format for negative numbers string Test = string.Format("{0:#,0;#,0-}", NegativeNumber); Results: PS C:\> '{0:#,0;#,0-}' -f -17.2 17- PS C:\> '{0:#,0;#,0-}' -f 17.2 17 Custom Numeric Format Strings The semicolon (;) is a conditional format specifier that applies different formatting to a number depending on whether its value is positive, negative, or zero.

At the beginning of every day, the first person who signs in the computer room will unlock the door, and the last one who signs out will lock the door. Given the records of signing in's and out's, you are supposed to find the ones who have unlocked and locked the door on that day. Input Specification: Each input file contains one test case. Each case contains the records for one day. The case starts with a positive integer M, which is the total number of records, followed by M lines, each in the format: ID_number Sign_in_time Sign_out_time where times are given in the format HH:MM:SS , and ID

I have a client that doesn't want my apple developer account to interfere with his application. So, can I use his developer account(without the credentials) to sign and test an application? I searched and I found myself lost with some questions over a possibility that I'm not sure it works. The thing I found was him exporting the developer profile via XCode, sending me the developer profile file and me importing that into my XCode. What I did not understand, however, was: will this thing work? will I need his account id and password for importing this, afterwards? (because this would be a
